## What it is
Docs.rs is the official documentation hosting service for crates published on crates.io, automatically building rustdoc documentation in sandboxed nightly Rust containers. The repository contains the Rust web server, build infrastructure, and tooling that power docs.rs.

## Use cases
- host documentation for my rust crate automatically
- build rustdoc docs for every crates.io release
- download rustdoc  for a crate programmatically
- configure custom docs.rs build features and targets
- run a local docs.rs instance for development
- get offline rustdoc archives for dash or zeal

## When to choose
- you publish Rust crates and want automatic documentation hosting
- you need programmatic access to rustdoc JSON or documentation archives
- you want to contribute to or self-host the docs.rs infrastructure

## When to avoid
- you need documentation hosting for non-Rust languages
- you just want to read Rust docs rather than build or host them
- you need a lightweight static site generator for docs

## Facets
- artifact type: service
- maturity: active
- function: documentation, build-tool, http-server
- domain: documentation, developer-tools, apis
- platform: rust, self-hosted
- tags: rustdoc, crates-io, docs-hosting, sandboxed-builds, rustdoc-, rust, docker, web-server
