The honest comparison
AuthZed (the company behind SpiceDB) and OpenFGA are the two leading open implementations of Google Zanzibar-style relationship-based access control (ReBAC). Both let you model fine-grained, relationship-driven permissions ("user X is editor of document Y") and check them at scale. SpiceDB/AuthZed emphasizes a production-hardened engine with commercial support and a managed offering; OpenFGA is a CNCF sandbox project originating from Auth0/Okta with a fast-growing community.
When AuthZed wins
- You want a commercially supported, production-proven Zanzibar implementation
- A managed service (AuthZed Cloud) or enterprise support is important
- Advanced features like consistency controls and large-scale performance are priorities
- You are standardizing fine-grained authorization across many services and want vendor backing
When OpenFGA wins
- You prefer a vendor-neutral, CNCF-governed open-source project
- Tight fit with the Okta/Auth0 ecosystem and its tooling is useful
- A straightforward developer experience and strong docs accelerate adoption
- You want to self-host without a commercial relationship
Pricing
Both have free open-source cores (SpiceDB and OpenFGA). AuthZed adds paid managed and enterprise tiers; OpenFGA is community-driven with managed options available through partners and the broader Okta ecosystem.
Verdict
Choose AuthZed when you want commercial support and a battle-tested Zanzibar engine behind your authorization layer. Choose OpenFGA for a CNCF-governed, community-first project, especially within the Okta ecosystem. For policy-as-code engines rather than ReBAC, compare OpenFGA vs Cerbos and see the authorization guide and category.
