Kastra
Runtime authorization for Claude, Cursor, Codex and OpenClaw
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.
Kastra is a Developer Tools company. It launched on Product Hunt on Jul 22, 2026, with 322 upvotes. Adamlead has 1 person on file at Kastra.
