Overview
Sentry is an application monitoring platform focused on developers. SDKs for most languages and frameworks capture exceptions with stack traces, context and the release that introduced them.
Teams use it to triage production errors, monitor performance with tracing, and watch session replays to see what users experienced. It is available as a hosted service, and a self-hosted version is also offered.
Key features
- Error trackingGroups exceptions into issues with stack traces, breadcrumbs and affected users.
- TracingFollows requests across services to identify slow transactions.
- Session ReplayReconstructs user sessions in web and mobile apps around an error.
- Release trackingLinks issues to commits and releases to find suspect changes.
- Alerts and integrationsRoutes alerts to Slack, issue trackers and on-call tools.
Best for

- Frontend and mobile teams that benefit from session replay
- Organizations that want an open, self-hostable option
