Flox gives developers reproducible software environments for the tools and frameworks used across a project’s lifecycle. Environments specify packages, variables, and shell hooks, with configuration managed as code, and are presented as working across macOS, Linux, and WSL2. Its Nixpkgs-powered catalog contains more than 190,000 packages. FloxHub supports syncing and sharing environments, with package lists, prior versions, and change logs available for review. GitHub Actions can install Flox and activate environments in CI workflows. A VS Code extension supports package management, environment activation, and running services; it is also compatible with Cursor. Flox Skills are described as helping Claude Code, Codex, and skills.sh agents create environments, services, and builds and onboard repositories. Flox says environments carry signed, hash-pinned software bills of materials and build provenance. Personal is free and includes three private FloxHub environments and five private packages. Team costs $20/seat/month and adds unlimited team environments and package publishing. Enterprise pricing is custom.
