AI increases the speed and volume of change across your entire software lifecycle—but your accountability stays the same. Flox provides deterministic foundations for autonomous workflows / probabilistic workloads, so velocity doesn't come at the cost of reliability, security, or compliance.
Trusted by teams building the future
Pin every dependency and define environments as declarative manifests. Upgrade or patch production by switching a single immutable reference; roll back by switching it back. Keep systems available and resilient as models and dependency matrices multiply.
Know exactly what's running in training -> evaluation -> prod. Hash-pinned, immutable Flox environments enable traceable releases with audit-ready provenance, actionable CVEs, and SBOMS by default.
Faster iterations, fewer regressions = quicker releases. Dev, CI, and prod run the same hash-pinned environments, agents and humans spend less time debugging setup, more time shipping validated releases. Deploy natively or as slim OCI images: either way, the hash is the unit of promotion.
Reduce rebuild churn, eliminate oversized images. Run the same deterministic, hash-pinned environments across dev, CI, staging, and prod—natively or exported to slim OCI images. Reproducible behavior at build time and runtime = fewer failed builds, fewer reruns, fewer rollbacks.
“Flox removes the risk of environment drift by letting you replicate your exact production environment during development, regardless of architecture differences between OS'es.”

Principal Software Engineer at Microsoft
“Flox takes the friction out of onboarding PostHog team members and contributors. Before, our local dev guide comprised 16 steps with 14 caveats. Now, it’s just a universal flox activate.”
Michael Matloka
Senior Product Engineer at PostHog
“When you ask me to build something, I don't just write code—I create the entire environment. With Flox, I can search packages, install dependencies, and build and run your app.”
