Product Idea from this Signal

A sandbox environment that tests OpenClaw upgrades against your agents before they break production

3.2k ▲

Every OpenClaw release breaks something. v2026.3.22 broke the Dashboard and WhatsApp. v2026.3.2 silently disabled all agent tools. v2026.3.8 killed cron jobs and compaction. v2026.3.28 permanently broke the exec tool in a way that downgrading could not fix. Users discover these regressions after upgrading their production instance. There is no pre-upgrade testing, no rollback plan, and no way to know if a new version will break your specific configuration. This tool creates a sandboxed replica of your OpenClaw setup, runs the upgrade there first, executes your critical workflows against it, and gives you a pass/fail verdict before touching production.
