This is a self-hosted Node.js bot that mirrors GitHub pull request activity into Slack—one channel per PR, showing reviews, comments, status changes, and review reminders—without writing anything back to GitHub except optionally a link comment. It's built on PostgreSQL for durability, uses a webhook-to-background-worker pattern to avoid timeout issues, and includes identity linking between GitHub and Slack accounts plus optional "quiet" channel archiving that doesn't spam notifications. The code is MIT licensed and appears production-ready with full docs, tests running offline against PGlite, health checks, and standard deployment patterns (environment vars, migrations). One open question: the source doesn't explain what problem this solves better than existing tools like Axolo or Pullfrog—it mentions taking design inspiration from Axolo but doesn't articulate a differentiation.
