authgraph

The client SDKs and CLI make setup incredibly convenient for rapid development cycles.

Authgraph has completely transformed how we handle permissions! The ability to define schemas in YAML and version them is a game changer for our team. I love that we can write relationship tuples directly and get answers in under ten milliseconds. The agent-first features with temporal grants and delegation chains are exactly what we needed for our AI integration. Having the MCP server and GitHub Copilot extension means our AI assistants can query permissions seamlessly. The audit logs capture every check and grant, giving us full visibility into compliance. It is amazing to have hierarchical permissions that cascade naturally through the graph traversal. We went from zero to production permissions in just minutes using the CLI. The fact that there is no latency overhead compared to competitors who vary between twenty and fifty milliseconds is incredibly impressive. This is truly production-grade access control that scales effortlessly.

The free tier offering of ten thousand checks per month without requiring a credit card is a very attractive entry point for small development teams looking to implement Zanzibar-grade access control without immediate financial commitment. The schema-driven approach using YAML allows for clear versioning and review in pull requests, which fits well into existing Git workflows. Having native hierarchical access through graph traversal rather than expensive recursive queries is a significant technical advantage. It remains unclear exactly how the agent-first temporal grants perform in complex delegation chains during peak usage, but the audit logging for every check appears comprehensive. For those needing MCP server integration, this solution seems ready to ship with minimal configuration overhead compared to rolling your own authorization layer.

The global distribution seems promising for low latency, though I am cautious about real-world edge performance under heavy concurrent load compared to the advertised metrics.

Authgraph provides a robust permission system with excellent sub-10ms latency and strong agent support features.
