Permit.io

In plain words

Permit.io is a permissions-as-a-service platform that handles access control for applications through role-based and relationship-based access control, policy-as-code, APIs, and a customer-facing interface. It is designed for developers who need to implement permissions management without building it from scratch. The service lets teams delegate permission handling so they can concentrate on their core product functionality.

From the sources

Every application requires managing permissions, and complexity is constantly on the rise. Permit.io provides permissions as a service (ReBAC, Policy as Code, APIs, and customer-facing UI), so developers can check this as done and focus on their core product.

Plug & Play App-Level Authorization. Enforce in Frontend or Backend Control via No-Code UI.

Implement secure, flexible, and reliable authorization out-of-the-box, and manage it with a no-code UI or API. Just add permit.check() to your code, middleware, mesh, or API gateway. Manage and audit who can grant, change and revoke permissions within your application's authorization system. Permit.io is a full-stack-authorization solution - covering all the layers required for building access-control for products and services - Infrastructure (e.g. Policy-engines, SDKS, APIs), Backoffice (the controls the team behind the product needs), and end-user interfaces (e.g. user management, audit logs, api-keys, and more). A key part of Permit.io’s infrastructure is the open-source combo of OPA /…from permit.io

  Hi HN, Gabriel, Co-Founder at Permit.io. We're releasing Permit MCP Gateway today, an authorization proxy for MCP servers. TL;DR - we built an MCP Gateway that developers love and CISOs trust. Watch more[0] Now, after your little hate on using fancy copy on HN, to the real thing: MCP is in a strange place. Developers are debating whether it's overcomplicated compared to CLIs or skills files. Meanwhile, enterprises are adopting it by default because every agentic system that acts on your behalf, Cursor, Claude, Copilot, internal agents, needs a stable infrastructure for connecting to tools.…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
