Oso is the “easy” button for authorization
Loved by Platform Engineering Teams
What we hear from engineers
“My customers want complex authorization features”
Meet enterprise requirements for fine-grained access control with Polar, our purpose-built language for authorization
“My authorization code is gross, and mind-numbing”
Centralize your logic without having to duplicate your data, using Local Authorization
“Data synchronization across services is brittle”
Clean, readable authorization logic — decoupled from your app code — that you’d be proud to demo
“I don’t want to be the one to mess up the authorization code”
Get unit tests, logs, and debugging, so you can make changes without breaking things
“I want to build AI apps without leaking sensitive data”
Get permissions-aware LLM responses by filtering vector embeddings

“I'm sold on this way ahead for the known future. Oso has nailed the abstractions.That’s the hardest part to get right, and the hardest part to change later.”
“Oso is a compelling fit because of their singular focus on authz, plus the flexibility of their Polar rule definitions. Within twenty minutes we’d managed to define a custom Polar definition to handle our current use case."
“We needed to manage authorization across all of our new microservices. The answer was the Oso authorization framework."
“Oso is A+. As we moved upmarket, being able to implement authz consistently and accurately helped us move faster and resolved a never-ending source of bugs.”
“We reviewed multiple solutions – Oso came out on top for its devex, scalable and consistent performance, and the flexibility to match all our needs.”
“It used to take us months to add new roles. With Oso we cut that time 10x. The Oso team has also been very helpful, making our migration super smooth.”
“Oso has been huge for us. It has the most intuitive model. It’s the most mature, and has the best tooling and docs. And the support has been unreal.”
“Oso was the fastest path to building roles and has been incredible – easy to wrap our heads around, great docs, and makes life much simpler.”
"We were able to build and deploy a sample app with Oso in an afternoon versus several days for the others. It was significantly faster to get started out of the box."
Let's see some code.
