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.
Benchmark releases to improve app health
Use the Releases dashboard to decide if a release is successful or needs to be rolled back. The crash rate indicator shows the percentage of sessions in a release that end in a crash, allowing you to compare release health and track improvements over time.
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.
