RunVouch watches cron jobs and unattended AI agents and tells you whether they did the work, not just whether they pinged. It alerts on a run that never started, stalled, exited non-zero, looped into a retry storm, went over its cost cap, or reported ok while the output file was never written. Free for 20 agents, no card.
Every finished run is hashed into a leaf, every day of leaves into a Merkle root, chained to the day before and stamped into Bitcoin with OpenTimestamps, so a run report cannot be edited afterwards, not even by us. Anyone can recompute those hashes in a browser without an account.
The client is a single Python file with no dependencies that wraps any command and fails open, so monitoring can never break the job it watches. Integrations for Claude Code, OpenClaw, n8n, GitHub Actions, cron, systemd, Slack, Telegram, PagerDuty and a remote MCP server. MIT licensed and self-hostable.
