About

What is Unfork?

We're a collective of engineers who got tired of building on top of fragile, closed-source AI infrastructure. So we started building our own — and open-sourcing everything.

Developer-First

CLI tools, not dashboards. Config files, not drag-and-drop. We build for engineers who ship from the terminal.

Local-First

Your data stays on your machine. Zero telemetry. Zero cloud dependencies. Run air-gapped if you want.

Truly Open

Apache 2.0 licensed. No “open core” bait-and-switch. The full product is the open-source product.

Built in Public

Every commit, every decision, every architecture doc is public. We don't hide behind private repos.
