Overview

Scalekit offers authentication and authorization for B2B SaaS apps (SSO, SCIM, RBAC, passwordless), free for up to 25,000 monthly active users with 1 SSO and 1 SCIM connection.

Good fit

Use Scalekit to add SSO, SCIM provisioning, or passwordless login to a B2B SaaS app without building identity infrastructure from scratch.

  • B2B SaaS startups
  • indie developers
  • small teams needing SSO

Not a fit

Avoid if you need more than 1 SSO/SCIM connection or more than 25,000 MAUs without upgrading to a paid plan.

  • need multiple SSO connections free
  • need unbranded auth on the free plan
