Welcome to the GitHub repository for crates.io, the official package registry for the Rust programming language.
crates.io serves as a central registry for sharing "crates", which are packages or libraries written in Rust that you can use to enhance your projects. This repository contains the source code and infrastructure for the crates.io website, including both frontend and backend components.
This service is maintained for you by the crates.io team, with support from the Rust Foundation. File hosting is donated by Amazon Web Services, with CDN services donated by Fastly.
We welcome contributions from the community! Whether you're fixing a bug, implementing a new feature, or improving documentation, your contributions help make crates.io better for everyone.
crates.io is built with Rust for the backend services. More specifically, the axum web framework and diesel for database access, with a custom-built background worker system. The frontend is a SvelteKit application written in TypeScript.
