Reproducible dev environments.

For you, your teams, and your agents.

Get Started

Devtools as dependencies


Each project gets its own tool versions, switched automatically as you change directories — kubectl, terraform, go, or anything else. One nem.toml covers tools that would otherwise each bring their own version manager.

Same environment everywhere


Commit nem.lock and pipelines, containers, and AI coding agents install exactly the same tools — same versions, same digests. Rootless container images drop nem into CI jobs and dev containers cleanly.

Works behind firewall


Host catalogs and packages with your own OCI registry, and audit them like any other artifact. Installs are checksum-verified and never need root — fit for regulated and air-gapped networks.
