rust-lang/rust is the main source code repository for the Rust programming language, according to its own README: it holds the compiler, the standard library, and the project's documentation together in one place. The README frames Rust around three points: performance suited to critical services and embedded devices, reliability from a type system and ownership model that catch memory and thread-safety bugs at compile time, and productivity through tooling like Cargo, rustfmt, Clippy, and rust-analyzer. It's licensed under a dual MIT/Apache-2.0 scheme with some BSD-like licensed portions, and its Rust and Cargo trademarks are owned by the Rust Foundation.

Tauri is an open-source framework at tauri-apps/tauri for building desktop and mobile apps by pairing a Rust backend with a web frontend of the developer's choice. The README describes small, fast binaries rendered through the operating system's own webview via WRY, with a built-in bundler, self-updater, system tray, and native notifications, released under Apache-2.0.

Vaultwarden is a Rust reimplementation of the Bitwarden Client API for people who want a self-hosted, Bitwarden-compatible vault without running Bitwarden's own resource-heavy server.

Public APIs is a community-curated GitHub repository listing free, publicly accessible APIs across a wide range of categories, with auth type, HTTPS, and CORS noted for each entry. It's a browsable reference, not a library to install.
