An open-source, self-hosted approval inbox and tamper-evident audit trail for AI agents proposing consequential actions.

Landing page captured for the 2026-09-24 issue.
For
Teams governing AI agents that can move money or change production systems
Worth noticing
The homepage’s audit demo invites visitors to rewrite a refund amount in an exported bundle and recompute its hash chain.

Field notes

The workflow is shown as five steps: propose, pause, decide, resume, and prove. The example integrations include framework-specific packages and an MCP gateway, while the sample API uses separate requests to submit an approval and poll for a decision. A downloadable audit bundle is used in the browser demo; the page describes offline verification, but the extracted evidence does not establish production performance.
