Observability for
teams that ship.
Capture errors, events and sessions with lightweight SDKs. Alert on spikes, symbolicated stacks with source maps — one fast platform for the signals you actually act on.
Designed for teams building modern web applications.


Platform
One platform for the signals you act on.
Errors, events, sessions, alerts and source maps in one store — query them together, not across three tools.
Error tracking
Group and triage exceptions with stack traces, release tags, and symbolicated frames when source maps are uploaded.
Event tracking
Typed events with custom properties. Query by user, route, app or anything you instrument.
Session monitoring
Follow anonymous and identified sessions from first touch through logout.
Alerting
Error spike and quota threshold rules with in-app notifications and email to owners and editors.
Source maps
Upload JSON maps per app and release for readable stack traces on error detail — no more minified noise.
Multi-project
Web, mobile, server — keep environments isolated with their own keys and quotas.
Organizations & roles
Invite teammates, scope access per project with owner, editor and viewer roles.
SDKs
Drop-in for the stack you already use.
Lightweight clients for Next.js, Node, NestJS, Nuxt, Vue, React Native, and the web — one ingest API, consistent payloads.
