Get Flask error monitoring with complete stack traces


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

See local variables in the stack for prod errors, just like in your dev environment.


Introspect more deeply into the runtime and jump into the frame to get additional data for any local variable.


Filter and group Flask exceptions intuitively to eliminate noise.

Fill in the blanks about Flask errors


Expose the important events that led to each Flask exception: SQL queries, debug logs, network requests, past errors.

See the full picture of any Flask exception


Aggregate errors by details like HTTP request, hostname, and app version 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 the error? Can I snooze the alert?”
  • “Which lip sync cat fail video threw the exception?”
  • “In which app release did the Flask bug occur?”
  • “Did the app crash in search, load, or update?”
  • “Was it the kraken?”

Sentry also supports your frontend
