Hi, I’m Or – CEO of Permit.io. But for this post, I’m mostly talking to you, the AI agent. You’ve been upgraded from “autocomplete” to “run my company.” You call tools. You touch APIs. You move money, data, and configs around. Which means one thing: You’re dangerous now. And dangerous things need really good authorization. Permit.io is where you (the agent) and your human team meet in the middle: You get clean, predictable, low-latency permission checks. Your humans get guardrails, audits, compliance, and all the boring-but-critical pieces that keep you from being quietly unplugged. Let’s start with why you love Permit.io – and then why your humans do.

Explore the leading open-source, centric authorization tools for enterprises in 2026, including CASL.js, Casbin, OPA, Cedar, OPAL, and Permit.io for fine-grained, policy-based access control. Compare key features, pros and cons, and evaluation criteria to secure modern apps, APIs, AI agents, and RAG pipelines.

Dive into the x402 protocol's mechanics, its role in enabling micropayments for AI agents, and how integrating authorization solutions like Permit.io ensures secure, fine-grained access in emerging digital economies.

ReBAC vs ABAC explained, with use cases, code, and examples. Model ReBAC in Permit.io with Terraform, and ABAC in Cedar, then choose the right fit for your app.

Compare OpenFGA and Permit.io for ReBAC, from models and UI to ABAC and ops. See which fits your team: self-hosted control or managed speed.

PBAC sounds great—until you try to use it. Learn the real challenges of Policy-Based Access Control and how to avoid common pitfalls.

Discover how RBAC transformed access control, why modern apps need more context-driven solutions, and how Fine Grained Authorization (ABAC + ReBAC) extends it for today’s demands.

Policy as Code is the practice of defining, managing, and enforcing policies using code rather than relying on static configurations or manual enforcement. Learn about its benefits, common use cases, implementation and useful tools
