Jekyll vs Next.js：2026年應該選擇哪一個？
靜態簡潔性與全棧React功能之爭
Choose Jekyll if you need a dead-simple static blog or docs site hosted on GitHub Pages with zero JavaScript and minimal configuration. Choose Next.js if you need dynamic features like authentication, API routes, server-side rendering, or a full-stack React application. If you're a Jekyll user who just wants faster modern static sites without full-stack complexity, consider Astro instead of Next.js.

What is Jekyll?
Jekyll is a Ruby-based static site generator that transforms Markdown and Liquid templates into plain HTML. It pioneered the modern static site movement and remains the default generator for GitHub Pages. It does one thing — build static sites from flat files — and does it with minimal configuration.
What is Next.js?
Next.js is a full-stack React framework that supports static generation, server-side rendering, incremental regeneration, API routes, and edge functions. It's the dominant React meta-framework in 2026, used for everything from marketing sites to complex SaaS applications. It provides a complete application platform, not just a static site generator.
Key Differences
Architecture: Static Generator vs Full-Stack Framework
Jekyll is a pure static site generator — it reads Markdown files, applies Liquid templates, and outputs flat HTML. There's no server, no runtime, no JavaScript. Next.js is a full-stack React framework with SSG, SSR, ISR, API routes, middleware, and edge functions. They're fundamentally different tools that happen to overlap only in the ability to produce static HTML.
JavaScript and Interactivity
Jekyll ships zero JavaScript by default. If you want interactivity, you manually add script tags. Next.js ships the entire React runtime (~85-100KB) on every page, enabling rich client-side interactivity, state management, and component-driven UI. For content-only sites, Jekyll's zero-JS approach delivers better raw performance. For interactive applications, Next.js is the clear winner.
Dynamic Capabilities
Jekyll has none. No server-side rendering, no API routes, no database connections, no authentication. Every page is pre-built HTML. Next.js can do everything — fetch data at request time with SSR, expose API endpoints, connect to databases via Server Actions, handle auth with middleware, and run code at the edge. If your project needs any dynamic behavior, Jekyll simply can't do it.
Build Performance and Scalability
Jekyll's Ruby-based build process slows down noticeably past a few thousand pages. Next.js with Turbopack handles large sites more efficiently, and ISR means you don't need to rebuild the entire site for content changes. For small sites, Jekyll builds are fast and simple. For large content libraries with frequent updates, Next.js scales better.
Developer Experience and Ecosystem
Jekyll requires Ruby and offers a straightforward Markdown-to-HTML workflow that anyone can learn in a day. Next.js requires Node.js, React knowledge, and understanding of modern JavaScript tooling — but gives you access to npm's massive ecosystem, TypeScript, component libraries, and headless CMS integrations. The trade-off is simplicity versus capability.
Performance Comparison
| Metric | Jekyll | Next.js |
|---|---|---|
| TTFB | Excellent — pure static HTML served from CDN | Varies — excellent with SSG/ISR, slower with heavy SSR |
| Build tool | Ruby / Kramdown | Turbopack / SWC |
| Base JS bundle | 0KB (no JavaScript by default) | ~85-100KB (React runtime) |
| Lighthouse range | 95-100 | 70-100 |
SEO Comparison

Jekyll
- Zero JavaScript output by default means blazing fast page loads and perfect Lighthouse scores.
- Extremely low learning curve — Markdown files, Liquid templates, done.
- Native GitHub Pages integration with free hosting and automatic builds.
- Stable, battle-tested tool that's been around since 2008 with predictable behavior.
- No dynamic capabilities whatsoever — no SSR, no API routes, no database access.
- Ruby dependency can be painful to set up, especially on Windows.
- Build times degrade significantly on sites with thousands of pages.
- Plugin ecosystem is aging and many plugins are no longer actively maintained.
Next.js
- True full-stack capability — SSG, SSR, ISR, API routes, Server Actions, middleware all in one framework.
- Massive ecosystem with React's component library access and extensive third-party integrations.
- Incremental Static Regeneration lets you update static pages without full rebuilds.
- Built-in image optimization, font loading, and script handling boost Core Web Vitals.
- Vercel deployment provides zero-config scaling with edge functions and global CDN.
- Significant learning curve — React, App Router, server components, and data fetching patterns take time to master.
- Ships ~85-100KB of JavaScript minimum due to the React runtime, even for static pages.
- Vercel-centric ecosystem means some features work best (or only) on Vercel's platform.
- Overkill for simple content sites — you're paying a complexity tax for capabilities you may not need.
When to Choose Jekyll
- You need a simple blog or documentation site hosted on GitHub Pages for free.
- Your content is purely static Markdown and you don't need any dynamic features.
- You want the simplest possible static site setup with minimal tooling.
When to Choose Next.js
- You're building a web application with authentication, database access, and dynamic user experiences.
- You need a mix of static marketing pages and server-rendered dynamic content in one project.
- Your team already knows React and wants one framework for everything from blog to dashboard.
- You need ISR to update content frequently without triggering full site rebuilds.

Frequently Asked Questions
Next.js對於簡單部落格來說是否過度設計？
可能是的。Next.js帶來了完整的React運行時、伺服器端渲染和API路由——這些簡單部落格其實都不需要。如果你只是在寫Markdown文章並想要快速的靜態輸出，Jekyll或Astro會用更少的開銷完成工作。Next.js適合在需要身份驗證、動態內容或應用功能與部落格共存時使用。否則，你會背負很多不必要的重量。
Jekyll能否處理搜尋或評論等動態功能？
不能原生支援。Jekyll產生純靜態HTML——沒有伺服器運行時。你可以使用Algolia進行搜尋或Disqus進行評論等第三方服務，但處理表單提交、身份驗證或資料庫查詢不是Jekyll開箱即用的功能。如果你需要這些功能，你要麼堆疊多個外部服務，要麼就改用Next.js這樣的框架。
我應該從Jekyll遷移到Next.js或Astro嗎？
這取決於你實際需要什麼。動態功能——使用者身份驗證、API路由、伺服器端渲染、個性化——這是Next.js的領域。但如果你想要更快的靜態建置和現代工具，又不需要完整的應用框架，Astro是更好的遷移目標。它原生處理Markdown內容，這使得從Jekyll遷移變得不那麼痛苦。
Jekyll在2026年仍在維護中嗎？
Jekyll仍在維護中，但開發速度已大幅放緩。現有網站和GitHub Pages部署保持穩定，所以如果你運行著一個Jekyll網站不必驚慌。不過，Ruby靜態網站生態已被JavaScript工具所超越。如果你開始新專案，值得思考Jekyll有限的功能集和老化的外掛生態是否真的是正確的權衡。
Jekyll和Next.js的SEO表現如何比較？
兩者都能產生可靠的SEO結果——它們都輸出搜尋引擎可以無問題爬取的HTML。Jekyll的靜態HTML既快速又簡潔。Next.js提供更多功能杆桿：動態頁面的SSR、自動圖片最佳化、內建元資料API、ISR保持內容新鮮。對於純靜態內容，它們大致相當。一旦SEO需求變成動態，Next.js就有優勢。
Jekyll和Next.js的學習曲線差異是什麼？
Jekyll學習起來簡單得多。寫Markdown、使用Liquid樣板、執行build命令——基本上就這樣。Next.js需要理解React、JSX、伺服器元件、資料獲取模式、檔案型路由和App Router。如果你還不是JavaScript開發者，上手會很陡峭。Jekyll可以讓你在一個下午就有生產力。
