AI agent auth from day one; built specifically for agentic workflows including MCP server authorization
Rapid prototyping and Google-native stacks; low-friction auth for AI apps that don't need agent-specific authorization
Limitations
Newer product with smaller community and ecosystem compared to Auth0 or Clerk; enterprise support is still maturing
No token delegation, no FGA, no agent SDK; vendor lock-in to Google Cloud; limited authorization model
Supported Not supported Unverified
