Get Koa error monitoring with complete stack traces


A minimalist illustration of a user interface that alludes to the Koa error tracking information features of Sentry.

See source code at each frame instead of settling for just line and column numbers.


Get proper asynchronous context tracking — like thread-local storage in a way that fits Koa’s concurrency model.


Filter and group Koa exceptions intuitively to eliminate noise.

Fill in the blanks about Koa errors


See what the app was doing when the Koa error occurred: HTTP requests, database queries, console log statements, etc.

See the full picture of any Koa exception


Aggregate errors by factors like request details, user ID, and event level to see what’s new, a priority, or a trend.

Assign custom tags to reproduce the error environment specific to your application, business, and users.

  • “How actionable is this error? Should I snooze the alert?”
  • “Did too many professional network matches cause the crash?”
  • “Has an error with the same stack occurred before?”
  • “In which app release did the Koa error happen?”
  • “Is Mercury in retrograde?”

Sentry also supports your frontend

Resolve Koa errors with max efficiency, not max effort

Learn in which version a bug first appeared, merge duplicates, and know if things regress in a future release.

Add commit data to automatically suggest an owner of each Koa error and instantly send deploy emails.
