# Free tools

Try KYE Protocol™ hands-on, free, in your browser — no install and no signup. Every tool below runs in minutes: build an authorize call in the sandbox, score where authority for an AI action ends, map your agents and the actions they carry, or verify a signed Evidence Pack™ from public keys alone.

Each tool runs against the real rail or a deterministic preview of it, so you can evaluate the governance model before you commit a single day of integration. This page is a derived projection of the free tier of the KYE Protocol™ [offering inventory](https://kyeprotocol.com/inventory/), so it never drifts from what is actually free.
