Docusaurus

What it is for

Docusaurus is a local docs-site generator: you open a generated docs page with a sidebar and a named article, and the MIT app is $0. Use it when the job is a docs page you start at a public $, not when you need a $20 chat seat.

What makes it unique: the cover is Docusaurus’s official generated docs page (Profilo Docs / GitHub, sidebar Introduction / Getting Started / Architecture / Trace Processing, Getting Started, Use a prebuilt .aar with Gradle, numbered steps 1. / 1.1 / 1.2 / 2. / 3., implementation fileTree(dir: 'libs', include: ['*.jar', '*.aar'])) from the Profilo docs still on facebook/docusaurus — not a pricing card. The Gradle steps themselves are ops of the docs page.

Key features

• Generated docs page — sidebar + article + code on the published site (cover still; docs). One desk. Cover Getting Started / .aar sit here. Docs / GitHub in the header sit here as CTAs, not a sixth desk.
• Sidebar / navbar — the tree you move between pages from (cover Introduction / Architecture). A nav, not a Gradle cell.
• Versioning — shipped version dropdowns (docs). A version, not a step number.
• Search — local or Algolia DocSearch (docs). A search, not an article heading.
• MDX / Markdown — the files you write that become the page (docs). A source file, not the published H1.
• Blog / i18n — optional blog plugin and locales (docs; i18n). A plugin, not a sidebar row.

Docs / GitHub on the cover are CTAs (not desks). App $0 is the meter. There is no hosted Docusaurus Cloud $ on docusaurus.io — do not invent one.

Who it's for

Best fit: docs teams who will stay on the MIT generator at $0 while they open a first docs page, then add their own host (GitHub Pages / Netlify / any static host) — not a paid docs SaaS unless they want hosted auth / seats.

Pricing

Verified 2026-10-23 (Asia/Shanghai). Docusaurus is MIT on facebook/docusaurus. docusaurus.io does not print a Cloud seat $. Do not invent a hosted $.

• Docusaurus — $0. npm @docusaurus/core. Generate a static site from Markdown / MDX. Host it yourself.
• Algolia DocSearch — optional search. The Docusaurus docs describe the integration; they do not print an Algolia $. Confirm Algolia’s own cards if you buy search.
• Hosting — GitHub Pages / Netlify / any static host you choose. Those bills are not Docusaurus Cloud.

Confirm your host’s checkout. There is no Docusaurus Pro tile.

Limitations / costs

• You host the build. A $0 generator is not a $0 SLA.
• No official Cloud seat. For a hosted docs desk see Mintlify or GitBook.
• A generated docs page, not Mintlify’s API playground. For that playground see Mintlify.

Alternatives

• Mintlify — a hosted API playground when you want Starter $0 / 5 seats, not Docusaurus’s Profilo Getting Started.
• GitBook — a hosted docs site when you want GitBook Free $0, not a local static build.
• ReadMe — a developer hub when you want ReadMe Starter $0, not Gradle-on-the-page.

Official tutorial

Intro chrome on the video is ops of the generated docs page, not generate-on-the-article. @docusaurus exists as a handle; the film we oEmbedded is the Meta Open Source upload.
