Bridging the worlds: pixi reimplements pip and conda in Rust
summary
Pixi reimplements conda and pip ecosystems as a single Rust binary and claims a working, cross‑platform package manager and task runner. It integrates the new SAT solver resolvo, adopts the PyPI client uv, and supports reproducible lockfiles and project-scoped environments. Benchmarks show about 10× speed versus conda and ~3× versus mamba. Demos install mixed C++/Python projects, run Whisper and build with CMake, and the tool produces reproducible lockfiles and cached task runs that actually work as shown.
