# docs generators i'd actually choose in 2026

> 50+ docs tools exist. most don't matter. here's the short list of documentation generators worth your time, with honest picks for each use case.

there are 50+ tools for building documentation sites. i've extracted docs from most of them. here's the truth: most don't matter.

this is the short list. the ones that are actually good. organized by what you should use, not alphabetically.

## tier 1: just use these

if you're starting a docs site today, pick one of these. they all expose markdown natively, work with agents, and won't waste your time.

**mintlify**: saas docs platform. connect your github repo, get a beautiful site, ai search, automatic `llms.txt`, and `.md` endpoints. if you want zero ops and maximum polish, this is it. the yc-backed default for startups in 2026.

**fumadocs**: next.js docs framework. open source, free, absurdly fast. if your project is already next.js, this is the obvious choice. exposes raw markdown endpoints. agent-ready by default.

**starlight**: astro's official docs framework. zero client-side javascript. the fastest docs site possible. built-in i18n, search, accessible navigation. if performance matters more than flashy features, pick this.

**vitepress**: vue-based, evan you's successor to vuepress. clean, fast, minimal. great for vue projects and anything that doesn't need react overhead.

## tier 2: solid, with tradeoffs

these are good. they have larger ecosystems or specific strengths. but they're not as effortless as tier 1.

**docusaurus**: meta's docs framework. huge ecosystem. powers react, redux, jest docs. mature, stable, deeply customizable. but no automatic `.md` endpoints. no auto `llms.txt`. extraction requires going to github or parsing html. good for large open-source projects with complex needs.

**nextra**: next.js + mdx from vercel. simple and effective. raw files in your repo. works well for next.js projects. less feature-rich than fumadocs but simpler to set up.

**gitbook**: from cli tool to venture-backed cloud. real-time editing, github sync, polished output. but custom extraction is harder. content is somewhat locked into their platform.

## tier 3: right tool for the job

these aren't general-purpose docs frameworks. they excel in specific contexts.

**mkdocs**: python docs standard. material for mkdocs theme is everywhere in data science and python projects. if you're python-first, this is your tool.

**sphinx**: the original python documentation engine. powers python's own docs. restructuredtext-based. verbose but thorough. if you need cross-references, api docs, and manuals, sphinx does it. if you just want a quick readme site, it's overkill.

**mdbook**: rust-based. zero dependencies. the tool that builds "the rust programming language" book. if you need a book, not a website, use this.

**11ty**: javascript ssg with zero client-side js. maximum flexibility. can be docs, blogs, anything. requires more configuration than dedicated docs tools.

## tier 4: avoid for new projects

**docsify**: renders markdown in the browser. sounds convenient. no build step. but the content isn't in the html, so extraction is painful. agents can't read it without headless browsers. new projects should use static generators instead.

**honkit**: community fork of the old gitbook cli. backward compatibility is its only reason to exist. don't start new projects with this.

**vuepress**: replaced by vitepress. still maintained but vitepress is the future.

## 50+ tools, grouped by what they build

for the obsessives, here's every tool i know about. most of these have specific niches or are legacy. the tiers above cover what you actually need.

**pure docs ssgs:** docusaurus, mintlify, fumadocs, nextra, starlight, vitepress, vuepress, docus, mkdocs, sphinx, mdbook, 11ty, hugo + docsy/hextra, zola, retype, doctave, honkit, docsify

**api docs renderers:** scalar, redocly, stoplight elements, rapidoc, swagger ui, postman, bump.sh, zuplo, aglio, widdershins, spectacle, dapperdox

**graphql docs:** magidoc, spectaql, graphdoc

**other spec tools:** asyncapi generator, protoc-gen-doc, typespec

**knowledge base / support platforms:** document360, zendesk guide, intercom, help scout, crisp, helpjuice, stonly, freshdesk, hubspot, tidio

**ai-native docs:** documentation.ai, docsalot, hyperdocs, docsio, docuwriter.ai, jamdesk

**developer portals / hosted:** gitbook, readme, fern, developerhub.io, papervine, slite, unmint

## how to choose

**just want docs, zero setup:** mintlify

**next.js project:** fumadocs

**vue project:** vitepress

**python project:** mkdocs (material) or sphinx

**rust project:** mdbook

**maximum performance (zero js):** starlight

**massive open source project with complex needs:** docusaurus

**api docs from openapi spec:** scalar (modern) or redocly (enterprise)

**book-style documentation:** mdbook

## prefer a generator that exposes its markdown

most docs tools are fine. a few are great. the difference between "fine" and "great" is whether your docs are readable by machines as easily as humans.

tier 1 tools understand this. they expose markdown natively. they generate `llms.txt`. they don't hide content behind javascript.

the rest make you work for it. and in 2026, that's increasingly a liability.
