Choose Better Auth if
TypeScript developers who want complete ownership and flexibility without paying per user.
- Free and MIT licensed; you own user data
- Comprehensive plugin set rivals hosted providers
- Excellent TypeScript DX
Look elsewhere if: Teams that want hosted UI and zero maintenance (Clerk) or heavy enterprise SSO today (Auth0).
Choose Scalekit if
Engineering teams that ship AI agents acting on users' behalf, or B2B SaaS products that need enterprise SSO and SCIM quickly.
- Agents act as the requesting user within the scopes that user granted
- One vendor for app SSO/SCIM and agent tool authorization
- Free tiers on both AgentKit and SaaSKit, with free dev and staging environments
Look elsewhere if: Consumer apps that only need simple social login, or teams that want a no-code automation tool (Clerk, Zapier).
