UMB is free for noncommercial use under the PolyForm Noncommercial 1.0.0 license, with the full source code on GitHub. A commercial license is a legal right, not a software unlock — there is no key to install, no activation, and no feature gate anywhere in the binary.
Personal projects, research, evaluation, anything non-commercial. Every feature, no limits, forever.
Commercial use at a small or growing company. Priced per developer up to 10, then a flat unlimited rate.

Prefer to pay by invoice or PO (NET-30)? That’s available on Enterprise — just mention it when you reach out.
Contact salesThe binary never phones home and enforces nothing. There is no license server, no machine fingerprint, no online check. A commercial license is paperwork — a certificate and agreement — not a code that flips features on.
Noncommercial use is free under the license, forever. Commercial use requires a paid license because PolyForm Noncommercial says so. Companies comply the same way they comply with any software agreement: because legal and procurement require it.
No tiers buried in the binary, no surprise metering, no audit telemetry. You can read every line. That openness is exactly what makes UMB easy to approve — and why we'd rather earn the commercial license than enforce it.
If you're using UMB at work to build or run something commercial, you need a commercial license. Tell us your setup and we'll point you to the right tier.
