SingleSign pricing
SingleSign pricing is simple: adding sign-in to your application is free, with no monthly-active-user meter and no per-application charge. SingleSign Business — company mail on a free name.singlesign.com address or your own domain — is priced per user.

Billing opens with the Business plan launch

Fair‑use rate limits
To keep the platform reliable for everyone, SingleSign applies rate limits to API endpoints and authentication flows. These limits are generous for normal usage patterns. If your application needs higher thresholds, contact us to discuss custom arrangements.
