# bugsnag — Automatic error monitoring for django, flask, etc.

License: permissive · Maintenance: active · Downloads: 691.1K/mo

## What it is and what it does

Bugsnag is the official Python notifier for the Bugsnag error monitoring service. It integrates into your application to automatically catch unhandled exceptions and send them to Bugsnag's servers, where you can view, analyze, and track them. The package is designed primarily for Django but also supports Flask and other Python frameworks. It depends only on webob, making it lightweight to add to existing projects.

The notifier captures exception details, stack traces, and contextual information about your application state when errors occur. Once configured with your Bugsnag API key, it handles transmission to the service in the background. The package is production-stable, actively maintained, and supports a broad range of Python versions from 3.5 to 3.12.

Use it for:

- Monitor unhandled exceptions in production Django applications and receive alerts when errors occur.
- Track and group similar errors across your application to identify recurring bugs and prioritize fixes.
- Integrate error reporting into a centralized observability workflow alongside other monitoring tools.
- Debug production issues by reviewing captured stack traces and application state at the time of failure.
- Automatically capture and report errors in Flask or other Python web frameworks without manual logging.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Bugsnag is an error monitoring notifier that automatically captures and sends exceptions from Python applications (including Django and Flask) to the Bugsnag service for tracking and debugging.

Yes, if you use Bugsnag's error monitoring service and need Python integration. The package is production-stable, actively maintained, has low install friction, carries no security vulnerabilities, and uses a permissive license. Install it when you want automatic exception reporting to Bugsnag rather than manual error logging.

## Install

pip install bugsnag
uv add bugsnag
poetry add bugsnag

## Installing bugsnag

Before you install: Low install friction with a single runtime dependency (webob). Actively maintained with a recent release within the last two months, supporting Python versions from 3.5 through 3.12.

License in practice: MIT license is permissive and imposes no significant restrictions on use, modification, or distribution in your own projects.

Quickstart:

pip install bugsnag

import bugsnag
bugsnag.configure(api_key="your-api-key")
bugsnag.notify(Exception("Test error"))

Requires a Bugsnag account and API key to send errors to the service; without it, the notifier will not transmit data.

Verify before relying:

- Whether the package supports real-time alerting or only batch error collection and reporting.
- What specific Django versions are tested and officially supported beyond the Python version classifiers.
- Whether Flask and other framework integrations are equally mature or if Django is the primary target.
