Open Source

Free tools, built by DEC-LLC, for everyone.

We believe infrastructure software that only the well-funded can access is infrastructure software that fails the community. These projects are open source (Apache 2.0 licensed), available on GitHub, and maintained by the same team that builds our commercial products.

Why we open source

"Open Ideas" isn't just a slogan. We release tools as open source because the infrastructure community gave us the foundation we build on — Linux, Rocky, PostgreSQL, Python, Ollama, and hundreds of other projects. Giving back isn't charity. It's how the ecosystem stays healthy.

Our commercial products are built on top of this same open foundation. The community editions of NIVMIA, IVMIA, OpenUTM, and VaultSync are free with registration — same security hardening as enterprise, same updates, limited to smaller fleets. If you outgrow the community tier, we're here. If you don't, keep using it.

Open Ideas. Real Tools. No Strings.

Every project above is available on GitHub.
Fork them. Use them. Contribute to them. Build on them.
