What is OpenFGA?

OpenFGA is an open-source framework for authorization that enables developers to build intricate access control systems using a user-friendly modeling language and API endpoints. Influenced by the principles outlined in Google's Zanzibar paper, it supports multiple access control models, such as Relationship-Based Access Control (ReBAC), Role-Based Access Control (RBAC), and Attribute-Based Access Control (ABAC). The framework offers software development kits (SDKs) in various programming languages like Java, .NET, JavaScript, Go, and Python, enhancing its versatility for diverse applications. Engineered for high performance, OpenFGA can carry out authorization checks in just milliseconds, making it suitable for both new startups and established organizations. As a project under the Cloud Native Computing Foundation (CNCF), OpenFGA emphasizes transparency and community involvement, inviting developers to engage in its ongoing development and governance. This collaborative effort not only adds value to the project but also guarantees that it adapts to the evolving demands of its user base. By fostering a vibrant community, OpenFGA aims to continuously improve and innovate its features, ensuring relevance in a rapidly changing technological landscape.

What is Grengin?

Grengin is an open-source AI platform that lets businesses give their teams secure access to leading AI models — without sensitive company data ever leaving their own servers. Unlike SaaS-only AI tools, Grengin runs on your infrastructure, so you stay in control of data privacy, compliance, and costs. Setup takes minutes, not weeks: choose a ready-to-go cloud marketplace image with sign-in already configured, or follow a simple guided wizard to get up and running. Once deployed, business leaders and IT teams get complete visibility and control over how AI is used across the company — set spending limits by department, decide which AI providers and models employees can access, and assign permissions based on roles or teams. Grengin also includes built-in reporting on usage by team and model, audit trails for compliance needs, and single sign-on support through Google and Microsoft (Azure AD), making it easy to fit into existing company workflows.
