In their own words
Pixi
Pixi is a package management tool for developers building reproducible project environments. It creates isolated environments that can be recreated from built-in lock files, and includes a task runner for project tasks and pipelines. Pixi supports Python and other languages, plus pyproject.toml and PyPI through uv. It can install global tools into isolated environments. For robotics workflows, it offers ROS 2 support through RoboStack for cross-platform development. Documented integrations cover VS Code, JetBrains, Zed, RStudio, JupyterLab, GitHub Actions, and Direnv. The VS Code Python extension can detect Pixi environments; a community-maintained Pixi extension adds task exploration and dependency management. Pixi runs on Linux, macOS, and Windows, with installation options including Homebrew, Windows Installer, Winget, Scoop, GitHub releases, and source installation. The software is free. Separate prefix.dev package-hosting plans include a free option and Pro at €42 a month, billed €500 annually; Enterprise hosting is available by quote. Enterprise builds can restrict allowed channels, proxy settings, certificates, and other policy-sensitive configuration.
