SpiceDB is an open source, Google Zanzibar-inspired, database system for creating and managing security-critical application permissions.

Developers create a schema that models their permissions requirements and use any of the official or community maintained client libraries to apply the schema to the database, insert data into the database, and query the data to efficiently check permissions in their applications.

Features that distinguish SpiceDB from other systems include:

Getting Started

Installing the binary

Binary releases are available for Linux, macOS, and Windows on AMD64 and ARM64 architectures.

Homebrew users for both macOS and Linux can install the latest binary releases of SpiceDB and zed using the official tap:

brew install authzed/tap/spicedb authzed/tap/zed

Debian-based Linux users can install SpiceDB packages by adding a new APT source:

sudo echo "deb [trusted=yes] /" > /etc/apt/sources.list.d/authzed-fury.list
sudo apt update && apt install spicedb

RPM-based Linux users can install SpiceDB packages by adding a new YUM repository:

sudo cat << EOF >> /etc/yum.repos.d/Authzed-Fury.repo
name=AuthZed Fury Repository
sudo dnf install spicedb

Running a container

Container images are available for AMD64 and ARM64 architectures on the following registries:

Docker users can run the latest SpiceDB container with the following:

docker run --rm -p 50051:50051 authzed/spicedb serve --grpc-preshared-key "somerandomkeyhere"

SpiceDB containers use Chainguard Images to ship the bare minimum userspace which is a huge boon to security, but can complicate debugging. If you want to execute a user session into a running SpiceDB container and install packages, you can use one of our debug images.

Appending -debug to any tag will provide you an image that has a userspace with debug tooling:

docker run --rm -ti --entrypoint sh authzed/spicedb:latest-debug

Containers are also available for each git commit to the main branch under ${REGISTRY}/authzed/spicedb-git:${COMMIT}.

Deploying to Kubernetes

Production Kubernetes users should be relying on a stable release of the SpiceDB Operator. The Operator enforces not only best practices, but orchestrates SpiceDB updates without downtime.

If you're only experimenting, feel free to try out one of our community-maintained examples for testing SpiceDB on Kubernetes:

kubectl apply -f

Developing your own schema

You can try both SpiceDB and zed entirely in your browser on the Playground thanks to the power of WebAssembly.

If you don't want to start with the examples loadable from the Playground, you can follow a guide for developing a schema or review the the schema language design documentation.

To get a quick idea of schema development, you can watch the creators of SpiceDB writing a schema for GitHub:

Trying out the API

For debugging or getting started, we recommend installing zed, the official command-line client. The Playground also has a tab for experimenting with zed all from within your browser.

When it's time to write code, we recommend using one of the existing client libraries whether it's official or community-maintained.

Because every millisecond counts, we recommend using libraries that leverage the gRPC API for production workloads.

To get an understanding of integrating an application with SpiceDB, you can follow the Protecting Your First App guide or review API documentation on the Buf Registry or Postman.


SpiceDB is a community project fueled by contributions from both organizations and individuals. We appreciate all contributions, large and small, and would like to thank all those involved.
