Mintlify
Replaceable in one session with an AI coding agent.
Documentation sites generated from Markdown with an interactive API playground, search and analytics, aimed at developer products that want docs to look designed.
Build a documentation site with a playground. STACK - Astro Starlight, or Docusaurus, over Markdown in your repository THE CONTENT - Markdown with front matter, in the same repository as the code it documents - A pull request that changes behaviour and not the docs should be visible in review THE API REFERENCE - Generated from one OpenAPI file, never written twice - A build step turning each operation into a page: parameters, responses, and an example request THE PLAYGROUND - A form generated from the operation schema, posting to a sandbox environment - The token is entered by the reader and kept only in memory — never in localStorage, never in a URL SEARCH - Pagefind builds a static index at compile time and needs no service WHAT PEOPLE COULD NOT FIND - Log searches with no clicked result; that list is the best documentation backlog you will get Include the OpenAPI build, the playground form and the search setup.
What you lose
- An interactive request playground generated from an OpenAPI file, with authentication handled
- Search tuned for documentation, and analytics on what people looked for and did not find
- A design system for docs that stays consistent as the site grows
If you would rather not build
- Docusaurus, with a large plugin ecosystem
- Docsify, for the very simplest case

73/100
Verdict yes at 73. Starlight plus Pagefind gets you most of it free; the playground is the piece worth building, and the failed-search log is the piece worth keeping.
