## What it is
Read the Docs is the open-source platform that powers readthedocs.org, a documentation hosting service that automatically builds, versions, and hosts documentation from Git repositories. It supports Sphinx, MkDocs, and custom documentation tools with continuous builds, pull request previews, search, and access control.

## Use cases
- host documentation for an open source project for free
- automatically rebuild docs on every git push
- preview documentation changes on pull requests
- host versioned documentation from branches and tags
- build sphinx or mkdocs docs in ci
- self-host a documentation build and hosting platform
- add search to project documentation

## When to choose
- you want automated, versioned documentation hosting with minimal setup
- your project uses Sphinx, MkDocs, or another common docs generator
- you need free hosting for open source project docs
- you want docs previews and search without running your own infrastructure

## When to avoid
- you need a fully static single-page docs site you can deploy anywhere yourself
- you want a static site generator rather than a hosting/build platform
- you need offline or air-gapped documentation delivery

## Facets
- artifact type: service
- maturity: stable
- function: documentation, ci-cd, search-engine, http-server
- domain: documentation, developer-tools, web-development, self-hosted
- platform: python, cloud
- tags: docs-as-code, sphinx, mkdocs, documentation-hosting, continuous-documentation, versioned-docs, web-server, docker
