Flox uses Nix to give teams reproducible, shareable development environments, dependency management, and SBOM tracking, from free CLI to $20/seat team plans.
Flox is a developer environment management platform built on top of Nix, the functional package manager known for byte-for-byte reproducible builds. Rather than asking developers to hand-maintain Dockerfiles or fight version mismatches between machines, Flox lets a team define an environment once and reproduce it identically on macOS, Linux, and inside containers or CI pipelines.
The company, FloxDev Inc, spun its technology out of quantitative finance firm D.E. Shaw and has since raised outside venture funding, including a 25 million dollar round reported in 2025. Flox environments can be activated with a single command and shared through FloxHub, the platform's cloud component for publishing and version-controlling environments the way a team would share code on GitHub.
Beyond reproducible environments, Flox layers in software supply chain visibility: teams get dependency tracking, software bill of materials (SBOM) generation, and provenance data so security and platform teams can see exactly what is installed where and push fast, traceable updates when a vulnerability surfaces.
Flox also targets AI-assisted development directly, with native support for the Model Context Protocol so AI coding agents can build and deploy inside a Flox environment, plus GPU-accelerated setups for CUDA and PyTorch workloads. Environments can deploy straight to Kubernetes without building a separate container image, and CI/CD integrations keep automated pipelines using the same environment definitions as local development.
Flox's Personal plan is free and includes the CLI environment manager, access to the public Flox Catalog, unlimited public FloxHub environments, three private environments, five private packages, and community support through Slack or Discourse.
The Team plan costs 20 dollars per user per month and adds a shared team catalog, unlimited private FloxHub environments, unlimited package publishing, platform-level support, and paid consulting from Flox's Nix packaging engineers. Enterprise pricing is custom and adds on-premises deployment options, a curated base catalog, a software policy engine, and more comprehensive packaging support.

Yes, Flox has native support for the Model Context Protocol, letting AI coding agents build and deploy inside a Flox-managed environment.
Flox can replace Docker for many development and deployment use cases, including deploying directly to Kubernetes without building a container image, though teams can also use Flox environments alongside existing container workflows.
