authzed

authzed is an authorization infrastructure platform that provides centralized permission management for application ecosystems. It offers a unified system for defining and enforcing access control rules across all your services and applications, eliminating the need for custom authorization code. The platform uses a flexible configuration language that allows teams to adapt to changing business requirements without rewriting code, making it suitable for complex permission models and custom workflows.

The system is built on SpiceDB, an open-source database that implements Google Zanzibar's authorization model. This provides strong consistency guarantees, global scale capabilities, and enterprise-grade performance. authzed handles billions of objects and delivers lightning-fast permission checks, ensuring uniform access control across all systems while protecting sensitive data and preventing security breaches.

This platform benefits engineering teams at companies of all sizes, from startups to enterprises like OpenAI, Workday, and Turo. It's particularly valuable for organizations that need to manage complex permission structures across multiple products or services, allowing developers to focus on building core product features rather than authorization infrastructure. Teams can implement fine-grained access control, support custom business logic, and scale their authorization system alongside their user growth.
