spicedb
An open-source, Google Zanzibar-inspired database for storing and querying fine-grained authorization data at scale.
What is spicedb?
SpiceDB is an open-source authorization database inspired by Google's Zanzibar system. It stores and evaluates fine-grained permissions, allowing applications to check whether a subject (like a user) can perform an action on a resource. It solves the problem of broken access control by providing a scalable, centralized service for managing authorization across complex architectures.
Platform and product teams building microservices or multi-tenant applications that require scalable, fine-grained authorization. It's also suitable for security engineers and developers implementing ReBAC (Relationship-Based Access Control) or ABAC (Attribute-Based Access Control) systems.
Developers choose SpiceDB for its production-proven scalability, faithful Zanzibar implementation, and multi-paradigm flexibility. Its ability to handle millions of queries per second with global consistency, combined with robust tooling for schema safety, makes it a reliable choice for critical authorization workloads.
