## Registries

A registry allows you to publish your Rust libraries as crate packages, to share them with others publicly and privately.

* [Crates](https://crates.io) - The official public registry for Rust/Cargo.
* [Cloudsmith :heavy_dollar_sign:](https://cloudsmith.io/l/cargo-registry/) - A fully managed package management SaaS, with first-class support for public and private Cargo/Rust registries (plus many others). Has a generous free-tier and is also completely free for open-source.
