## Summary

Our system has strong **system monitoring** (Beszel heritage) and good **domain monitoring** (Domain Locker inspired). The gaps are primarily in:

1. **Public-facing features** (Status pages)
2. **Enterprise integrations** (SSO, 2FA, Teams)
3. **Advanced monitoring** (Real browser, gRPC)
4. **API access** for external integrations

The chart library is now exportable and can be used in other projects.
