One environment.
Every developer.
Every agent.
One reproducible, governed stack from laptop to CI to production, so teams ship faster, eliminate drift, and know exactly what ran and where it came from.
Remove drift and brittle steps with certainty.
If your machines are inconsistent, it results in an ongoing troubleshooting tax. Your Platform Teams can offer a confident baseline to standardize on.
One setup, three machines
The same SETUP.md resolves to different versions on a laptop, in CI, and on an agent.
Pinning it by hand
Reproducing that stack in Docker means a multi-stage build, gigabytes of images, and a daemon.
Flox gives us a reproducible foundation we can trust, which matters more and more as our team grows. It also gives us a much more controlled path for shipping software fast and reliably.
Amin KarbasTechnical Staff, Resolve AIOne manifest, every target
Resolve once. Run identically everywhere.
One manifest resolves to one lock, and every target below runs that exact software. Go from mostly the same to exactly the same.
How the manifest workssource of truth
Change the manifest, and every target moves with it.
One declaration, every stage.
Declare it once, and the same locked environment carries all the way through, from development to production. No re-describing your stack at every stage.

Imageless Kubernetes
Or skip the image: a pod references the environment directly, so there are no multi-GB images to build or pull.
Reproducible builds and imageless Kubernetes, powered by Nix under the hood. You never write a line of it.
A supply chain you can defend.
Every environment carries a signed, hash-pinned software bill of materials. The security work most teams postpone is built into the workflow.
See CVE remediation in depthA deterministic SBOM
A hash-pinned bill of materials, read straight from the dependency graph. Not inferred after the fact.
CVE remediation in one bump
Know which environments a CVE hits. Bump one pin, rebuild, and roll back in one step.
Audit-ready provenance
Prove what shipped and how it was built. Evidence is a byproduct of the build, not a separate scan.
Enterprise platform
Standardize every environment your Platform Team supports.
Give every developer and agent the same ground truth, and give platform and security the controls to govern it across the org.
Identity and access
Bring your identity provider. SSO plus role-based control over who can publish, pull, and promote environments across the org.
Private distribution
Ship environments and packages from your own registry, on your network, air-gapped, with no dependency on the public internet.
Audit and provenance
Every environment carries a signed bill of materials and a full lineage, so compliance falls out of the lock instead of being bolted on.
Support with an SLA
A named team, response-time commitments, and a roadmap you can influence. The people who build Flox, on call for yours.
Bringing Nix to work, at enterprise scale.
Standardize every environment your platform, security, and ML teams run, on your own infrastructure.
Teams standardize on Flox.
From Fortune 20 platform teams to fast-moving startups, one declared environment stays identical everywhere it runs.
Before, our local dev guide comprised 16 steps with 14 caveats. Now, it’s just a universal flox activate.
Flox gives us a dependable foundation so we can move fast with tight feedback loops.
Flox helps bring simplicity to this space, making it approachable, while not hiding the opportunities and power in the tools.
Flox gives us a lean and secure alternative, plus makes it easy - an excellent double win.
Flox is a ground up new approach that will undoubtedly become a key part of future toolchains.
Flox successfully marries the simplicity of traditional package managers with the reproducible, hermetic foundation of Nix.
Every developer has their own long-lived VM and because of that, people have made minor modifications here and there to the system.
Flox is all I can expect from a package manager: simple, reliable, efficient, flexible.
