About Culltron

Software, intelligence and infrastructure — built local-first.

Culltron is a software ecosystem engineered in South Africa for the next economy: a free OS with useful apps, serious professional tools, and a flagship AI tier that you control — local, your own provider, or our cloud.

Free to enter

Culltron OS is a launch-candidate local-first workspace. Its five visible free utilities are the current free layer; per-app Lite bundles remain proposed and unshipped.

Local-first

Your files, your machine. Apps work offline; AI runs locally if you want it. Nothing is forced to the cloud.

AI on your terms

Flagship AI lives in Ultra X27 — powered by a local model, your own provider, or our optional cloud. Always your choice.

What we believe

Principles we build by.

Honest about what things are

Lite is free in the OS. Max is paid software. Ultra X27 is the flagship — not a bundle. We don’t blur the lines.

Privacy by architecture

Loopback-only runtimes, scoped access and signed leases. Security you can see in Sentinel — not a promise.

Open-source, credited

We build on open-source where it’s the right tool, publish attributions, and contribute back where we can.

Built for the next economy

Affordable, powerful software for creators, professionals and businesses — engineered in South Africa, for everyone.

Supported through startup grant programs.

Culltron has received grant credits through ElevenLabs, Microsoft Azure and MongoDB startup programs. These grants support product development and do not imply endorsement, partnership, sponsorship or investment.
