How ContractSpec pricing works now and next

We charge based on how much of your stack we help you maintain, not how many people click around in the UI.

Generous free tier

One serious project, small spec, and enough monthly regenerations to ship something real.

Usage-based beyond free

You pay for regenerations and AI agent actions, not per-seat. The more your system evolves via ContractSpec, the more you pay.

No lock-in

Generated code is standard, readable, and exportable. If you leave, your app keeps running.
