Kellnr is a self-hosted, open-source registry for Rust crates, like a private crates.io you run on your own hardware. It supports cargo out of the box, hosts rustdocs, provides a web UI for crate management, and can act as a caching proxy for crates.io.

Use cases

• host private rust crates for my company
• self-hosted alternative to crates.io
• cache crates.io downloads behind a proxy
• host rust documentation for internal crates
• set up a private cargo registry with docker
• manage crate versions with a web ui
• offline crate registry for air-gapped environments

When to choose

• you need private Rust crates that cargo can consume without extra tooling
• you want to cache/proxy crates.io to speed up or control dependencies
• you want self-hosted docs.rs-style documentation for your crates
• you need an air-gapped or on-premises crate registry

When to avoid

• you only publish public open-source crates, where crates.io is the standard
• you need a multi-language package registry (npm, PyPI, etc.) rather than Rust-only
• you don't want to operate any server infrastructure
