### What we like

Combines frontend and backend SDKs to provide end-to-end session replay and error tracing. Backend logging integrations link up to the relevant user session for easier debugging. Records network activity & console logs. Supports data masking for privacy. Open source so can be self-hosted, or use the cloud version.

### Tradeoffs

Can’t track WebSockets. Frontend session tracking has some client overhead (11kb bundle). The UI has no dark mode.
