Open Source Authorization & Permissions Software

Authorization & Permissions software manages how users authenticate their identities and which resources they can access across a network. These tools implement single sign-on and role-based access control to prevent unauthorized entry into databases, servers, and internal web applications. This type of software serves developers and system administrators who need to centralize login credentials and session management. By hosting these apps on private infrastructure, you keep user identity records and access logs on your own hardware instead of relying on external identity providers.

This page lists 13 open source tools in the Authorization & Permissions category. The most popular are Keycloak, Hasura and Netbird. Most use the Apache-2.0 or AGPL-3.0 license, and 13 offer an official Docker image.
