Pricing
Hobby is $0, one instance each. Then $299/mo, flat.
Hobby is $0, one instance each, then $299/mo with unlimited users and unlimited SSO connections, and $999/mo when you want staging alongside production. Both paid rungs start with a 30-day trial. The bill does not move when you win a customer. Effective 2026-08-07. On your own metal, the same engine ships under a licence. Why we price it this way is a dated note you can read.
The numbersOn your metalWhat never appearsCompared
Signing up creates your account and provisions your instance automatically, in minutes, with nobody waiting on us. You get its URL and its own compatibility receipt when it is live.
Three numbers. None of them move.
This is the whole price list. Users, sessions, and enterprise SSO connections are included. The bill does not change when you win a customer. Team and Business both start with a 30-day trial; checkout asks for a card and does not charge it until the trial ends. Hosted is billed monthly. A Scale licence, to run Signet on your own hardware, is billed yearly. There is no annual hosted plan and no monthly/yearly toggle: one number per line.

Flat means flat. There is no per-user tier, no overage line, and no usage meter: your bill does not move when you win a customer. On your own metal, a licence: Scale at $15,000/yr on standard terms, or an enterprise licence quoted per deployment.
Support on any paid plan is support@signetauth.com. You get a reference number back and the request goes on a queue, not into one person’s inbox.

On your own metal.
Hosted is the only one with a price on a table. Three others are quoted per deal: a Scale licence to run Signet on your own hardware, fixed-price implementation from a migration sprint to an advisory retainer, and testing your agent setup against the identity provider your customer runs.
quoted per deploymentThe same certified build on your own hardware, watermarked to you and licence-enforced offline, sold as an annual licence per production deployment. Never a free download, and never metered. Two rungs: Scale at $15,000/yr on standard click-through terms when you just need the engine on your metal, and a quoted Enterprise licence when the deal needs air-gap delivery, source escrow, or named support with an SLA. What the licence covers →
from $15,000Named, fixed-price engagements: a $15,000 migration sprint, a $45,000 enterprise landing, or a $4,000/mo advisory retainer. Fixed scope, fixed price, no day rates. What each engagement covers →
Four lines that never appear on your invoice.
These four cannot appear. There is nothing in the engine that could produce them.
