We build tools for the conda ecosystem. We've build a new package manager (pixi), a website that indexes conda packages (https://prefix.dev), a tool to build conda packages from source (rattler-build) and much more. All of these tools are powered by Rattler, a complete reimplementation of the conda ecosystem in Rust. In this talk we will walk you through some of the technical feats that went into the library like a completely Rust based SAT solver, the different components of the library and how the library might also benefit you!
