Flox v1.16 is out. Run a package on demand, without creating an environment or installing anything. Plus: new plugins for 1Password, Vault, OpenBao, and Infisical. Secrets stay with the provider and become available when you activate. More: buff.ly/XAEDEq8

The faster agents build, the less tolerance there is for inconsistency in the environments where they work. Reproducibility is what ensures that AI agents always build, test, and debug in exactly the same environment. Captured at PlanetNix 2026.

Signing a person in and authenticating a pipeline are two different jobs. FloxHub now treats them that way. Today, we are announcing two new credential types for FloxHub: Service Account Tokens for automation, Personal Access Tokens for people. Full writeup: buff.ly/Qdhjrk9

Auto-activation is here for Flox environments. Walk into a directory with a .flox folder and the environment turns itself on. Nested environments and services come along too. Your environments become one less thing to think about. Read the full post here: buff.ly/8CYRuSbhttps...

One tool. Every language. Declare Python, Node, Go, Rust, or whatever your project needs in a single Flox environment. Flox activate, and the exact versions you pinned land first on PATH. Same on macOS and Linux, no containers. Change a version? That's a reviewable diff. buff.ly/de8Wb25

People keep asking how to set up their AI stack as code. So here's the pattern: one Flox file — packages, versions, services — that your whole team activates. Same stack on macOS, Linux, WSL2, CUDA or Metal. Link here: buff.ly/PVaRl8m

Getting the same environment twice was never easy. Now a coding agent installs dependencies and changes your system while you're not looking causing your laptop to drift further from prod. Flox CPO James Bayer gets into it on Temporal's Vibe Check: buff.ly/HWaXb38

Shai-Hulud doesn't break in. It gets installed, then reads whatever credentials are lying around and ships them off. A hermetic build keeps nothing lying around: no ambient creds, no network. It can't steal what it can't see. Link to full blog: buff.ly/Xw2Jie6

It trains on your MacBook then it hits Slurm and dies: wrong CUDA, missing libs, broken paths. Not another container. One Nix-pinned environment, identical from laptop to cluster to prod. We trained nanoGPT on Slurm to prove it: buff.ly/JJJd5yP

Dev containers or Nix-style environments? False choice. Declare your runtime — language, libraries, build tools, CLIs — natively on the host with Flox, Nix, or Guix. Keep backing services in containers. The same split runs local → CI → prod. buff.ly/Y27BWgA

Happy to say that I've been using Flox for a couple of weeks and so far (after some initial networking weirdness that wasn't Flox's fault) it's Just Worked. The rest of my team is still getting used to it, so it's possible we'll encounter new pain points in the future, but so far it's been great!

Fellow.ai hit a familiar scaling problem: “works on my machine” in local dev, CI/prod bugs, costly rework. With Flox, Fellow.ai got reproducible dev environments that work across laptops, CI, and prod—reducing onboarding friction, environment drift, and downstream risk. Full blog in the comments!

“Works on my machine” isn’t a joke. It means local dev has become shared infrastructure without being managed that way. Strict isolation is one path to reproducibility. Declared, locked environments are another: portable, verifiable, and better suited to local autonomy. full blog in the comments!

Found a new use for @flox.dev today - was able to reproduce a bug involving communication between Ceph clients of two different versions. Before flox I probably would have set up 2 VMs with different versions of the packages installed but instead I was able to just run my tests from 2 flox envs

Security teams are often asked to certify where they can only infer. Scans, SBOMs, attestations, tickets, approvals; no confident answer to: do we know what’s running and how it got there? Secure software by construction starts with versioned, auditable runtimes. buff.ly/YxdymBY

CVE remediation is a dependency-graph problem. Scanning attempts to infer from built artifacts. Flox/Nix derive artifacts + runtimes from the causal dependency graph. Remediation = dbms lookup + declarative edit: identify artifacts/envs, pin a replacement ref, promote. Read more in the comments!

We talk a lot about #AI right now, but this keeps coming up in conversations: determinism and reproducibility. If code is being generated by agents, and systems are getting more complex, you need to be able to answer a pretty simple question: what actually ran? Ron on this at PlanetNix 2026 👇
