The source code and infrastructure for crates.io, the official package registry for the Rust programming language. It includes a Rust backend built with axum and diesel, a SvelteKit/TypeScript frontend, and a custom background worker system.

Use cases

• search for Rust packages
• publish a crate to the Rust registry
• browse crate documentation and versions
• query the crates.io API for package metadata
• download Rust dependencies via cargo
• contribute to the Rust package registry website

When to choose

• you want to publish or discover Rust packages
• you need programmatic access to Rust package metadata via an API
• you want to contribute to or self-study the infrastructure behind a large package registry

When to avoid

• you need a package registry for languages other than Rust
• you want a lightweight self-hosted registry for private crates without significant infrastructure work
• you just need to install Rust packages - use cargo directly instead
