Kastra is the runtime authorization layer for AI agents. It decides what agents can and cannot do before actions execute, enforcing policies with sub-1 ms latency across tools, prompts, inputs, and outputs. Use one control plane to govern agents and policies across Claude Code, Cursor, Codex, OpenClaw, the Anthropic SDK, the OpenAI SDK, and more. Prevent unauthorized tool use, prompt injection, and exposure of sensitive data before they become incidents. Trust the rules, not the agents.













I use Kastra everyday to discover the risks while coding and it’s very useful.
Highly recommend 👍🏻

@carlos_campos93 This is great, thank you. We're happy we can bring value to you!
I have been testing kastra with my team and even though I’m not very technical it’s very simple to use and it has helped us a lot while building our product.

@paula_jimenez4 Kastra is great for new builders learning how to code; it teaches them the risks and helps them understand the agentic coding workloads better by being able to evaluate all the actions, risks, and decisions at runtime.

This is the kind of infrastructure that won't get the loudest headlines, but could become a core part of every serious AI stack. As agents gain more autonomy, authorization becomes just as important as intelligence. Congrats to the entire team and wishing you an amazing launch
