Flox
United States
What it is
Flox provides reproducible software environments containing tools and frameworks developers need across the software lifecycle. Environments define project packages, variables, and shell hooks, and can be managed as code. Flox presents them 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 to view. GitHub Actions can install Flox and activate environments in CI workflows. A VS Code extension supports package management, environment activation, and running services, and is also compatible with Cursor. The free Personal plan includes three private FloxHub environments and five private packages. Team costs $20/user per month and adds unlimited team environments and package publishing. Enterprise pricing is custom. Flox says environments carry signed, hash-pinned software bills of materials and build provenance. The company says it was originally built to help D. E. Shaw group developers adopt Nix at scale.
