Pricing
The tools are free. Professional services and support are $3 a contracted hour per seat.
plumb and goldspec are Apache-2.0 and run on a laptop, in your CI or on-premise, with no call out to us and no credential. Nothing in them stops working if you never pay.
What is paid is what only a hosted service can do. The unit is a seat you already staff: $3 a contracted hour per seat, from one week at $120 — $6,000 for a full-time year, the form that fits a proposal line.

Subscribing asks you to sign in first. If you have no account, signing in opens one with your work address — there is nothing to install to buy, and the people who look after billing never need the tool.
