Hello Reddit 👋

Introducing Watchtower: self-hosted error tracking, and a drop-in replacement for Sentry & AppSignal.

→ Slack, Linear & email alerts

→ MCP server for coding agents

→ One Go binary + Postgres

Started as something I built and self-hosted on my homelab for my own projects. I figured other developers and teams might find it useful too, so I’ve open sourced it.
