openfga/go-sdk

The go-sdk is a Go client library for OpenFGA, an open source fine-grained authorization system inspired by Google's Zanzibar paper.

OpenFGA solves the problem of implementing scalable, reliable permission systems in applications. The go-sdk provides a wrapper around the OpenFGA API, enabling Go developers to interact with OpenFGA services for managing authorization models, relationship tuples, and permission checks. The tool supports core operations including store management, authorization model versioning, relationship tuple management with watch capabilities, and various query types such as check, batch check, expand, list objects, and list relations. It also includes support for assertions, custom headers, retries, and OpenTelemetry integration for observability.

Developers should choose this SDK when building Go applications that need to integrate fine-grained authorization. It suits projects requiring flexible permission modeling beyond simple role-based access control, particularly those at scale where reliability and low latency matter. The SDK is autogenerated from the OpenFGA API definition, ensuring consistency with the service specification.

The project maintains active engagement with community contributions through structured issue and pull request processes. Development follows established patterns for SDK maintenance with documented contribution guidelines. The tool provides comprehensive API coverage including less common features like streamed list operations and relationship tuple change watching, indicating attention to operational requirements beyond basic authorization queries.
