Best For
Multi-tenant SaaS, token delegation for agents, fine-grained authorization at scale
AI agent auth from day one; built specifically for agentic workflows including MCP server authorization
Limitations
Vendor lock-in on cloud plan; self-hosted (Private Cloud) is enterprise-tier only; dynamic client registration for MCP requires Enterprise plan to secure against abuse
Newer product with smaller community and ecosystem compared to Auth0 or Clerk; enterprise support is still maturing
