Permit.io
Full-stack authorization infrastructure that empowers developers to build permissions in minutes.
What it does
Provides a visual dashboard for non-technical team members to manage user roles and permissions. Offers an SDK and sidecar (PDP) for real-time authorization enforcement in apps. Maintains an open policy administration layer (OPAL) for policy-as-code management. Supports fine-grained access control models including RBAC, ABAC, and ReBAC (Google Zanzibar style). Includes 'Permit Elements'—embeddable UI components for user-facing permission settings.
Why it works
Efficiency: Removes the repetitive task of building custom IAM mechanisms, saving months of engineering time. Empowerment: Low-code interfaces allow Product and Support teams to adjust access without opening a Jira ticket. Scalability: Built on top of OPA (Open Policy Agent), ensuring enterprise-grade stability and performance. Visibility: Provides a single source of truth for all authorization logic across microservices.

Founder story
Founded in 2020 by Or Weis and Asaf Cohen in Tel Aviv, Israel. Or, an experienced software leader, was tired of building the same authorization logic at every company he joined. They built Permit.io to turn 'Authorization' into a solved infrastructure problem, similar to how Stripe solved payments.
