Overview
PropelAuth is hosted authentication aimed squarely at B2B products. Organizations are a first-class concept, with hosted org-management pages, invitation flows, membership rules, seat limits per org and RBAC with custom roles. It also covers passwords, magic links, social login, MFA, attack protection, API keys and M2M auth, and OAuth 2.1 auth for MCP servers.
The free plan allows 10,000 monthly active users with unlimited organizations, custom roles and a custom domain, but shows PropelAuth branding and has no enterprise SSO, impersonation or API keys.
Growth at $150 a month is where the product's pitch lands: unlimited SAML, OIDC and enterprise SSO connections, user impersonation, a separate staging environment, API keys and MCP authentication, then $0.05 per MAU above 10,000. Growth Plus at $500 adds per-org MFA enforcement, password complexity rules and SCIM at $100 per connection. For a B2B product with many small SSO customers, flat unlimited SSO can be much cheaper than per-connection pricing.
