# Sentry

> Error tracking + performance monitoring with rich context. The standard for production apps.

[Sentry](https://sentry.io) tracks uncaught errors, performance regressions, and unusual behavior. Stack traces, breadcrumbs, source maps — everything you need to debug production issues.

<Note>
  Full walkthrough being written.
</Note>

## What you get

* Error grouping and deduplication
* Stack traces with source maps
* User context (which user was affected)
* Performance traces (slow queries, slow renders)
* Release tracking (which deploy introduced the bug)

## Setup

`VITE_SENTRY_DSN` (client) and `SENTRY_DSN` (server) in vly env vars. Use `@sentry/react` on the client and `@sentry/node` in Convex actions.
