Free to 50,000 MAU. Then $19/mo.
Signet is Free to 50,000 MAU — then $19/mo plus $0.01/MAU over 50k, ratified 2026-07-21 as a decision of record, not a placeholder. That is $19 where Clerk starts at $25 and $0.01 where Clerk meters $0.02. Founding terms and enterprise conversations start below.

On honesty about price. Signet’s pricing is a ratified decision, recorded 2026-07-21 — not a placeholder, and not a number that moves next week. $19/mo is the hosted service; taking the engine on-prem is an enterprise licence, quoted separately. What is not metered either way is your data: users, sessions, and secrets sit in your own PostgreSQL from the first sign-in, so the exit is an export you already control, not a rebuild.
