Automatic Python error reporting
Get visibility into application errors and take a proactive approach to code quality
Get started with just a few lines of code
pip install bugsnag and configure your API key. Once you’ve integrated, the notifier library will begin detecting errors and notify you automatically.

Receive real-time alerts on errors
Send notifications to Slack, email, PagerDuty, and more. You can customize your alerting rules to make sure you’re only alerted to important errors.
Prioritize errors and improve your debugging workflow
Bugsnag’s integrations and workflow tools allow you to effectively prioritize harmful exceptions and move them through a debugging process to get them resolved for your customers.
Comprehensive Python exception reports
Get to the root cause of exceptions faster with detailed exception reports
Stacktrace with code snippet
See the line of code that crashed including a code snippet for every error to make it easier to understand where in your code an error happened.
User and environment data
Bugsnag automatically captures diagnostic data like request information, session data, and more. It also captures user information in order to correlate errors with customers.
Customize your error reports
Bugsnag automatically captures as much information as possible, but since all apps are unique, you can easily customize your report and send the data you need to assess and reproduce every error.
