GitBook

YES

Replaceable in one session with an AI coding agent.

Documentation hosting with an editor anyone can use. Pages are written in the browser or synced from a repository, and readers get navigation, search, versions and a published site under your own domain.

Promptfree, for everyone, and the only version there is

Build me a documentation site that is fast, searchable and readable with scripting off.

STACK
- Astro in static output, Markdown and MDX content collections
- Deployed as static files, no server

CONTENT
- Docs as files in a directory tree; front matter for title, description, order and an optional redirect-from list
- The sidebar is generated from the tree and never hand-maintained

SEARCH
- A build-time JSON index and a small hand-written scorer
- Title matches weighted above headings, headings above body
- Keyboard navigation, and no external search service

READING
- Table of contents per page from the headings, with a scroll-spy highlight
- Syntax-highlighted code with a copy button and per-language tabs
- Callout components for note, warning and danger

VERSIONS
- A directory per version and a version picker
- A canonical link from an old version to the current page, so search engines are not confused

THE SMALL THINGS THAT MATTER
- An "edit this page" link to the repository on every page
- Open Graph images generated at build time, plus a sitemap
- A 404 that suggests the nearest pages using the same search score

BUDGET
- Under 15KB of JavaScript, and every page readable with scripting disabled

Include a README on the index format, the scorer weights and how to cut a version.

Why this verdict

our own opinion · changed only by a person

78/100

Verdict yes at 78: static documentation is one of the best-solved problems there is, and at $65 per site per month the arithmetic is not close. The genuine loss is a WYSIWYG editor for non-technical colleagues, which is why this is not in the nineties.
