Rich Text Editor Bundle Size Comparison 2026: 12 Editors Measured

Rich Text Editor Bundle Size Comparison 2026: 12 Editors Measured

Bundle size has become one of the most consequential decisions when picking a rich text editor for a modern React or Next.js app in 2026. Core Web Vitals directly affect SEO rankings. Lighthouse scores gate mobile-first indexing. Users on 4G connections abandon pages that take longer than 3 seconds to interact with. A single 500 KB editor bundle can push your Time to Interactive above the threshold where Google measurably ranks your pages lower.

Most editor comparison content treats bundle size as a single number reported by vendors. Reality is more complex. The "bundle size" that matters is the actual measured JavaScript delivered to browsers after tree-shaking, gzip compression, and production build optimization — not the marketing-page number that assumes ideal conditions.

This guide measures 12 rich text editors as they actually ship to production in 2026 — bundled with esbuild + gzip, tree-shaken aggressively, and tested with the same React 19 baseline app. Every measurement includes both the core editor bundle and the minimum realistic feature set (toolbar, tables, image handling) most production apps require. Real numbers, real methodology, honest carve-outs.

The short answer: For teams optimizing Core Web Vitals in 2026, Quill (~45 KB) and Lexical (~90 KB) are the lightest options but require substantial additional engineering for production readiness. Eddyter at ~140 KB provides the best balance — complete production-ready editor with AI, tables, and 7-framework support at a bundle size similar to lightweight framework alternatives. CKEditor 5 (~500 KB) and TinyMCE (~500 KB) hurt Lighthouse scores measurably and should be avoided for consumer-facing SEO-sensitive pages.

TL;DR — Bundle Size Rankings in 30 Seconds

• 🥇 Lightest overall: Quill (~45 KB) — but stalled development, no AI, no advanced features
• 🥈 Lightest framework: Lexical (~90 KB) — free MIT, but 4-6 weeks to production
• 🥉 Best complete editor: Eddyter (~140 KB) — full features + AI, 10-min setup, 7 frameworks
• ⚠️ Avoid for SEO-sensitive apps: CKEditor 5 (~500 KB), TinyMCE (~500 KB), Froala (~350 KB)
• 📊 Lighthouse impact: Every 100 KB above baseline costs 0.5-1.2 seconds on 4G
• 💰 SEO cost of heavy editors: Measurable ranking drops on mobile-first indexed pages

Why Bundle Size Matters More Than Ever in 2026

Bundle size affects three specific product outcomes in 2026 that directly translate to revenue and growth metrics.

1. Core Web Vitals Directly Affect SEO Rankings

Google's Core Web Vitals — LCP (Largest Contentful Paint), INP (Interaction to Next Paint), and CLS (Cumulative Layout Shift) — are confirmed ranking factors as of 2021 and increasingly weighted through 2026. Heavy editor bundles push LCP above the 2.5-second "Good" threshold and INP above the 200ms threshold on mobile devices. Pages failing Core Web Vitals rank measurably lower than competitors' pages that pass.

For content-heavy apps where editor pages are indexed by Google (documentation platforms, blog CMSs, help centers, knowledge bases), a 500 KB editor bundle can cost 15-30% of organic traffic compared to the same content shipped with a lightweight editor.

2. Mobile Users Abandon Slow Pages

Mobile users on 4G connections (the majority of global mobile traffic in 2026) experience roughly 5-10x slower JavaScript parsing than desktop users. A 500 KB editor bundle that takes 200ms to parse on desktop takes 1-2 seconds on mid-tier mobile devices. During that parsing time, the page appears frozen — users abandon.

Google's own research shows 53% of mobile users abandon pages that take longer than 3 seconds to load. Editor bundle size directly contributes to that abandonment threshold.

3. Bundle Size Compounds With Every Feature

Modern web apps ship many features simultaneously — routing, state management, analytics, monitoring, authentication, and rich text editing all compete for the same JavaScript budget. A 500 KB editor eats 25% of a typical 2 MB total JavaScript budget for a single feature. That leaves less room for the features that differentiate your product.

Lightweight editors (Eddyter at ~140 KB, Lexical at ~90 KB, Quill at ~45 KB) preserve JavaScript budget for actual product features. Heavy editors force feature trade-offs.

Measurement Methodology

Bundle size numbers vary widely based on measurement methodology. Here's exactly how these numbers were measured for 2026 accuracy.

Test Environment

• Framework: Next.js 15.1 with React 19.0
• Bundler: esbuild via Next.js production build
• Compression: gzip level 6 (standard CDN default)
• Tree-shaking: Aggressive with sideEffects: false where supported
• Baseline app: Vanilla Next.js starter with only the editor added
• Measurement tool: @next/bundle-analyzer for per-package accounting

What "Measured" Bundle Size Includes

Two numbers matter for realistic comparison:

Core editor bundle — the JavaScript required to render a basic editor with typing, formatting (bold, italic), and paragraph support. This is the number vendors typically publish.

Production-realistic bundle — the JavaScript required for a production app: core editor + toolbar + tables + image handling + heading formatting + list support. This is what actually ships to your users.

The gap between "core" and "production-realistic" is often 2-3x for framework-based editors (Lexical, TipTap, Slate) where you pay separately for each extension. Complete editors (Eddyter, CKEditor 5, TinyMCE, Froala) have smaller gaps because features come bundled.

What's Excluded

• Editor server infrastructure (only client-side JavaScript measured)
• Y.js and other collaboration libraries (measured separately in the RTC comparison)
• AI provider SDKs (OpenAI, Anthropic, Google — separate from editor bundle)
• CSS bundle size (typically 5-30 KB, not the primary optimization target)
• CDN-loaded fonts (asynchronous, don't block initial render)

The 12 Rich Text Editor Bundle Size Rankings (2026)

Here's how the 12 leading rich text editors compare on measured production-realistic bundle size:

Key patterns:

• Under 200 KB: Quill, Lexical, Slate, Eddyter, BlockNote, TipTap, ProseMirror, Draft.js
• 200-400 KB: MDXEditor, Froala
• Over 400 KB: CKEditor 5, TinyMCE

For Core Web Vitals optimization, target under 200 KB total editor bundle. Above 400 KB, Lighthouse scores measurably degrade on mid-tier mobile devices.

1. Quill — Lightest Editor for Simple Use Cases

Core bundle: ~45 KB | Production bundle: ~52 KB | License: BSD-3 | Best for: Prototypes, basic formatting, MVPs

Quill has the smallest bundle in the ecosystem — approximately 10x lighter than CKEditor 5 or TinyMCE. Its BSD-3 license permits unlimited commercial use across any number of domains without cost.

Where Quill wins on bundle size:

• Smallest core bundle among all evaluated editors
• Minimal production bundle bloat (Quill doesn't need many extensions for basic formatting)
• Simple mental model — no plugin registry to import

Where Quill loses despite bundle advantage:

• Development has stalled since 2022 (no active maintenance)
• Known React 19 compatibility issues in community react-quill wrapper
• No AI features and no roadmap
• No advanced tables or slash commands
• Known paste-handling bugs

For teams optimizing purely for bundle size on simple use cases, Quill remains competitive. For any product needing modern features, the bundle advantage doesn't offset the feature gap. See Quill Alternative 2026 for migration paths.

2. Lexical — Smallest Framework With Modern Architecture

Core bundle: ~90 KB | Production bundle: ~130 KB | License: MIT | Best for: Custom editor builds with 4-6 weeks of engineering runway

Lexical is Meta's editor framework — the same foundation Eddyter is built on. Its bundle size is the smallest among modern editor frameworks, and Meta's active maintenance makes it a strong foundation for custom builds.

Where Lexical wins on bundle size:

• Smallest core bundle among modern editor frameworks
• Excellent tree-shaking with sideEffects: false
• Production bundle stays under 150 KB with typical feature set
• Free MIT license across unlimited domains

Where Lexical loses despite bundle advantage:

• Framework only — 4-6 weeks minimum to production
• You build toolbar, tables, AI features, mobile UX
• Custom plugin engineering ($40,000-$60,000+ development cost)
• No collaborative features out of box

Teams wanting Lexical's bundle advantages without the 4-6 week build often adopt Eddyter (built on Lexical) instead. See Best Lexical Alternative 2026 and Lexical vs TipTap 2026.

3. Slate — Lightweight React-Native Custom Framework

Core bundle: ~120 KB | Production bundle: ~180 KB | License: MIT | Best for: Custom React document models

Slate provides comprehensive document model flexibility with a bundle size competitive with Lexical. Best when your product requires unique content structures — legal contracts with clause-level annotations, medical records with regulated fields, structured AI reasoning traces with metadata.

Where Slate wins on bundle size:

• Competitive core bundle with Lexical
• React-native from initial design (no wrapper overhead)
• Free MIT license
• Total document model flexibility

Where Slate loses:

• Historical breaking changes between versions
• React-only (no Vue, Angular support)
• 4-6 weeks minimum engineering investment
• Documentation less comprehensive than Lexical

For analysis, see Eddyter vs Slate 2026 and TipTap vs Slate 2026.

4. Eddyter — Best Complete Editor at Lightweight Bundle Size

Core bundle: ~140 KB | Production bundle: ~140 KB | License: Proprietary + free tier | Best for: Modern React/Next.js apps needing complete editor with AI

Eddyter's bundle size advantage is architectural. Because it's a complete editor (not a framework requiring add-ons), the core bundle equals the production bundle — no plugin bloat, no extension coordination overhead. Everything ships together in ~140 KB gzipped.

Where Eddyter wins on bundle size:

• Complete editor at framework-size bundle — full features at 140 KB is architecturally unique
• No add-on bloat — toolbar, tables, images, AI all included in base bundle
• Aggressive tree-shaking with sideEffects: false
• Lightweight compared to complete editors (3.6x lighter than CKEditor 5, 3.6x lighter than TinyMCE)
• 7-framework support — same bundle works across React, Next.js, Vue 3, Angular 17-20, Svelte 4/5, Laravel, Vanilla JS

Where Eddyter loses:

• Slightly larger than pure frameworks (Lexical, Quill) that ship without UI
• API-key subscription required for production (free tier available)

5. BlockNote — Notion-Style at Mid-Range Bundle

Core bundle: ~180 KB | Production bundle: ~220 KB | License: MPL 2.0 | Best for: Notion-clone products with block-based UX

BlockNote provides Notion-style block editing at a mid-range bundle size. Complete UI ships built in — you get slash commands, blocks, and drag-and-drop without custom engineering.

Where BlockNote wins on bundle size:

• Reasonable bundle for a complete block-based editor
• Slash commands and block UX built in
• React-native architecture

Where BlockNote loses:

• React-only (no Vue, Angular, Svelte)
• MPL 2.0 has copyleft implications for some enterprise legal reviews
• AI features require paid plan
• Larger than Eddyter despite simpler feature set

For comparisons, see BlockNote vs TipTap 2026 and How to Build a Notion-Style Block Editor in React 2026.

6. TipTap — Bundle Grows With Extensions

Core bundle: ~165 KB | Production bundle: ~245 KB | License: MIT core + Cloud | Best for: Custom headless React UIs

TipTap's bundle demonstrates the framework-extension trade-off clearly. Core bundle is competitive (~165 KB), but production bundle grows quickly as you add the 15-30 extensions typical apps require for parity with complete editors.

Where TipTap wins on bundle:

• Reasonable core bundle
• Modular architecture allows removing unused features
• MIT core covers unlimited domains

Where TipTap loses on bundle:

• Extensions add up quickly (each @tiptap/extension-* adds 5-30 KB)
• Production apps typically ship 200-300 KB after realistic feature set
• AI Toolkit adds another 50-100 KB when integrated
• Cloud collaboration adds Y.js overhead

For deeper analysis, see TipTap Pricing Explained 2026 and Best TipTap Alternatives 2026.

7. ProseMirror — TipTap Foundation, Direct Usage Larger

Core bundle: ~180 KB | Production bundle: ~280 KB | License: MIT | Best for: Legal, technical, or scientific editors requiring precise document control

ProseMirror is the framework TipTap is built on. Using it directly gives complete control but requires more code than TipTap for equivalent functionality — the production bundle typically exceeds TipTap's for identical feature sets.

Where ProseMirror loses on bundle:

• Larger production bundle than TipTap for equivalent features
• Framework only — no UI, no toolbar
• Steepest learning curve in the ecosystem
• 6-8 weeks minimum engineering investment

Best for: teams with existing ProseMirror expertise or unique requirements that TipTap's abstractions don't accommodate. For most teams, TipTap or Lexical are the better ProseMirror-family choice.

8. MDXEditor — MDX Support at Bundle Cost

Core bundle: ~250 KB | Production bundle: ~290 KB | License: MIT | Best for: MDX-formatted content rendering

MDXEditor uniquely supports MDX (markdown + JSX components) natively. The MDX processing adds bundle overhead but enables use cases no other editor supports cleanly.

Where MDXEditor wins on bundle:

• Only editor with native MDX handling at this bundle size
• Built on Lexical foundation (modern architecture)
• Free MIT license

Where MDXEditor loses on bundle:

• Larger than base Lexical due to MDX processing
• Streaming AI support partial (flickering during token bursts)
• No native mid-generation edit handling

For markdown-specific analysis, see Best Markdown Editor Components for React 2026.

9. Froala — Commercial Editor at High Bundle Cost

Core bundle: ~350 KB | Production bundle: ~380 KB | License: Per-domain paid | Best for: Existing Froala installations

Froala's bundle size approaches CKEditor 5 territory without the collaborative features that justify CKEditor's larger footprint. Combined with per-domain licensing complexity, Froala is a difficult recommendation for new 2026 projects.

Where Froala loses on bundle:

• 2.7x heavier than Eddyter with fewer features
• Per-domain licensing scales badly for SaaS products
• AI features cost extra
• No Svelte or Laravel support

For migration analysis, see Eddyter vs Froala 2026 and Best Froala Alternatives 2026.

10. CKEditor 5 — Heavy Bundle for Complete Enterprise Features

Core bundle: ~430 KB | Production bundle: ~500 KB | License: GPL + commercial | Best for: Enterprise deployments requiring compliance today

CKEditor 5's bundle size reflects its comprehensive feature set — real-time collaboration, track changes, revision history, and SOC 2 Type II certification all ship together. For enterprise deployments where these features are required, the bundle cost is justified. For consumer-facing SEO-sensitive apps, it's a liability.

Where CKEditor 5 wins despite bundle:

• Complete enterprise feature set in one package
• SOC 2 Type II certified today
• Real-time collaboration built in
• Track changes and inline comments included

Where CKEditor 5 loses on bundle:

• 3.6x heavier than Eddyter
• Measurably degrades Core Web Vitals on mid-tier mobile
• 6-8x heavier than Lexical
• Cloud pricing ($144-$864/mo) adds cost to bundle problem

For migration analysis, see Best CKEditor Alternative 2026 and Eddyter vs CKEditor 2026.

11. TinyMCE — Legacy Bundle Architecture

Core bundle: ~450 KB | Production bundle: ~500 KB | License: LGPL + Cloud | Best for: WordPress ecosystem, Microsoft Word paste workflows

TinyMCE's bundle reflects its 22-year architectural evolution — legacy patterns predating modern tree-shaking, plugin coordination that adds overhead, and Word paste handling that ships with substantial supporting code.

Where TinyMCE wins despite bundle:

• Best-in-class Microsoft Word paste handling (PowerPaste)
• 22 years of stability
• Best WordPress ecosystem support

Where TinyMCE loses on bundle:

• 3.6x heavier than Eddyter
• Architecture predates modern React patterns
• AI Assistant is separate paid add-on (~$120+/mo)
• Editor-load pricing ($40 per 1,000 additional loads) creates cost multiplier on top of bundle problem

For migration paths, see TinyMCE Alternative and Eddyter vs TinyMCE 2026.

12. Draft.js — Deprecated, Bundle Irrelevant

Core bundle: ~180 KB | Production bundle: ~240 KB | License: MIT | Best for: Not recommended (Meta deprecated in 2022)

Draft.js is included in this comparison only for teams still running legacy Draft.js installations. Meta deprecated Draft.js in 2022 and migrated Facebook and Instagram to Lexical. New projects should never adopt Draft.js regardless of bundle size.

For migration paths, see Draft.js Is Dead: Best Draft.js Alternatives in 2026.

Bundle Size Impact on Core Web Vitals

Understanding how bundle size translates to Lighthouse scores clarifies the real cost of heavy editors.

LCP (Largest Contentful Paint) Impact

Bundle size directly affects how quickly JavaScript parses and executes. On mid-tier mobile devices (Moto G Power, Pixel 6a — representative of 60%+ of global mobile traffic in 2026):

Editor bundles above 400 KB routinely push LCP above the 2.5-second "Good" threshold on mobile, causing measurable ranking penalties.

INP (Interaction to Next Paint) Impact

Heavy JavaScript bundles slow initial page interactivity. INP measures how quickly the page responds to first user interaction. Editor bundles above 400 KB routinely push INP above the 200ms "Good" threshold on mid-tier mobile devices.

CLS (Cumulative Layout Shift) Impact

Bundle size doesn't directly affect CLS, but slow-loading editors that render synchronously can cause layout shifts if styles load after DOM. All measured editors handle this correctly when integrated properly.

Real-World SEO Impact

For content-heavy apps where editor pages are indexed by Google:

• Under 200 KB editor bundle: Passes Core Web Vitals reliably, no ranking penalty
• 200-400 KB editor bundle: Passes on desktop, borderline on mobile
• Over 400 KB editor bundle: Fails Core Web Vitals on mid-tier mobile, measurable ranking drops

For deeper analysis, see Best Rich Text Editor for Next.js App Router 2026 which covers Core Web Vitals optimization specifically for Next.js apps.

Bundle Size vs Features: The Trade-Off Matrix

Bundle size alone doesn't determine the right editor — features matter equally. Here's the trade-off framework:

Under 100 KB Bundle (Quill, Lexical)

Trade-off: Simplicity vs feature completeness

Pick if: You're building a prototype, MVP, or have engineering runway to build features. Quill for prototypes, Lexical for custom builds.

100-200 KB Bundle (Eddyter, Slate, TipTap core, BlockNote)

Trade-off: Balance point — complete features at reasonable bundle cost

Pick if: You need production-ready features without bundle-size penalty. Eddyter for complete editor, TipTap for headless flexibility, BlockNote for Notion-style UX.

200-400 KB Bundle (TipTap production, ProseMirror, MDXEditor, Froala)

Trade-off: Feature richness at moderate bundle cost

Pick if: You need specific features (MDX, custom document models) worth the bundle cost. Test Core Web Vitals impact before shipping.

Over 400 KB Bundle (CKEditor 5, TinyMCE)

Trade-off: Enterprise features and compliance vs measurable SEO impact

Pick if: You need enterprise compliance (SOC 2 Type II today) or Microsoft Word paste handling. Never for consumer-facing SEO-sensitive apps.

For most React/Next.js apps in 2026 balancing features with bundle size, the 100-200 KB tier is optimal — Eddyter, Slate, TipTap, or BlockNote depending on specific requirements.

Bundle Size Optimization Tips (Regardless of Editor Choice)

Whatever editor you pick, these techniques minimize bundle impact:

1. Code-Split the Editor Route

Load the editor JavaScript only on pages that need it:

jsx

1
2
3
4
5
import dynamic from 'next/dynamic';
const Editor = dynamic(() => import('@/components/Editor'), {
  ssr: false,
  loading: () => <div>Loading editor...</div>,
});

This keeps editor JavaScript out of your main bundle for pages that don't need it.

2. Tree-Shake Aggressively

For framework editors (TipTap, Lexical), import only the extensions you actually use:

jsx

1
2
3
4
5
6
// BAD — imports entire extension set
import StarterKit from '@tiptap/starter-kit';
// GOOD — imports only what you need
import Bold from '@tiptap/extension-bold';
import Italic from '@tiptap/extension-italic';
import Heading from '@tiptap/extension-heading';

3. Lazy-Load Advanced Features

Load AI, tables, and image handling only when users need them:

jsx

1
const AIPanel = dynamic(() => import('./AIPanel'), { ssr: false });

4. Use Production Builds

Always measure bundle size with production builds (next build) — development builds include debugging code that dramatically inflates bundle size.

5. Enable Compression

Ensure your CDN serves gzip or Brotli compression. Brotli typically provides 15-20% smaller bundles than gzip.

6. Choose Complete Editors When Feature Sets Match

Complete editors (Eddyter, CKEditor 5) often have smaller total bundles than framework editors (TipTap, Lexical) with extensive extensions loaded. The framework advantage requires disciplined extension management.

Best Editor by Bundle Size Requirement

Different products have different bundle-size tolerances. Here's the framework.

For Consumer-Facing SEO-Sensitive Apps

Pick Eddyter (~140 KB). Complete editor at framework-level bundle size. Passes Core Web Vitals reliably on mid-tier mobile.

For Enterprise B2B Apps (Bundle Size Less Critical)

Pick CKEditor 5 (~500 KB) if compliance requires SOC 2 Type II today. Bundle size less critical for internal enterprise tools.

For Notion-Clone Products

Pick BlockNote (~220 KB) or Eddyter (~140 KB). Both provide block-based UX. Eddyter smaller if you don't need block-specific features.

For Prototypes and MVPs

Pick Quill (~52 KB). Smallest possible bundle for basic formatting. Migrate to Eddyter or Lexical when scaling.

For AI-First Products

Pick Eddyter (~140 KB). Only editor combining AI (GPT-5, Claude Sonnet 5, Haiku 4.5, Gemini 3) with lightweight bundle. See Best Rich Text Editors for AI Apps 2026: Rendering LLM Output.

For Custom Editor Products (Editor IS Your Product)

Pick Lexical (~130 KB) or Slate (~180 KB). Framework flexibility justifies engineering investment.

For WordPress Ecosystem

Pick TinyMCE (~500 KB) despite bundle cost. WordPress compatibility outweighs bundle concerns for WordPress-specific deployments.

For framework-specific guidance, see Best Rich Text Editor for React 2026, Best Rich Text Editor for Vue 2026, and Best Rich Text Editor for B2B SaaS Apps 2026.

Frequently Asked Questions

1. What is the smallest rich text editor for React in 2026?

Quill has the smallest measured bundle at approximately 45 KB gzipped for the core editor. Lexical is second at approximately 90 KB. For production apps requiring modern features (advanced tables, AI, mobile UX), Eddyter provides the best balance at approximately 140 KB — complete editor with everything included, roughly 3.6x lighter than CKEditor 5 or TinyMCE. For prototypes needing minimal features, Quill wins on bundle size but lacks active development.

2. Does rich text editor bundle size affect SEO?

Yes, measurably. Rich text editor bundle size directly affects Core Web Vitals (LCP, INP, CLS), which are confirmed Google ranking factors as of 2021 and increasingly weighted through 2026. Editor bundles above 400 KB routinely push LCP above the 2.5-second "Good" threshold on mid-tier mobile devices, causing measurable ranking penalties on mobile-first indexed pages. For content-heavy apps where editor pages are indexed by Google, a 500 KB editor bundle can cost 15-30% of organic traffic compared to the same content shipped with a lightweight editor under 200 KB.

3. How can I reduce my rich text editor bundle size?

Six techniques minimize editor bundle impact: (1) Code-split the editor route using next/dynamic to load editor JavaScript only on pages needing it, (2) Tree-shake aggressively by importing individual extensions rather than starter kits for framework editors like TipTap and Lexical, (3) Lazy-load advanced features (AI, tables, image handling) only when users interact with them, (4) Use production builds (next build) for accurate bundle measurement, (5) Enable Brotli compression on your CDN for 15-20% smaller bundles than gzip, (6) Choose complete editors like Eddyter when feature sets match your requirements — complete editors often have smaller total bundles than framework editors with extensive extensions.

4. Why is CKEditor 5 so much larger than modern alternatives?

CKEditor 5's bundle size (~500 KB gzipped) reflects its comprehensive feature set — real-time collaboration, track changes, revision history, SOC 2 Type II compliance code, and 22 years of architectural evolution all ship together. Modern alternatives (Eddyter at ~140 KB, Lexical at ~130 KB) achieve smaller bundles through modern architecture, aggressive tree-shaking, and feature scope discipline. For enterprise deployments where CKEditor 5's compliance features are required, the bundle cost is justified. For consumer-facing SEO-sensitive apps, the bundle cost is a measurable liability that hurts Core Web Vitals scores and mobile-first indexing.

5. Which rich text editor has the best bundle size to features ratio?

Eddyter provides the best bundle-size-to-features ratio in 2026 — approximately 140 KB gzipped for a complete editor including AI features (GPT-5, Claude Sonnet 5, Haiku 4.5, Gemini 3 support), advanced tables with cell merging, slash commands, drag-and-drop image handling, mobile-responsive UX, semantic HTML output, and 7-framework support (React, Next.js, Vue 3, Angular 17-20, Svelte 4/5, Laravel, Vanilla JS). Lexical is smaller (~130 KB production) but requires 4-6 weeks engineering to build equivalent features. Quill is smallest (~52 KB) but lacks modern features entirely. For production apps needing complete functionality at lightweight bundle size, Eddyter is architecturally unique.

6. Should I choose a lightweight editor or a full-featured one for my Next.js app?

Depends on three factors: (1) SEO sensitivity of the pages containing the editor, (2) feature requirements for your product, (3) available engineering runway. For consumer-facing SEO-sensitive pages, choose editors under 200 KB — Eddyter for complete features, Lexical or Quill for custom builds. For internal enterprise tools where Core Web Vitals matter less, heavier editors like CKEditor 5 or TinyMCE can be acceptable if compliance features are required. For most modern Next.js apps balancing features with bundle size, the sweet spot is 100-200 KB — Eddyter provides the best complete-editor option in this tier, with Lexical or Slate as free framework alternatives requiring engineering investment.
