Detect exceptions in your Tornado applications

Automatically capture Tornado errors and detailed reports, so you can fix them for your users

Get Started

Automatic Tornado 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. View Tornado docs.

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.

Get alerted to errors affecting users

Bugsnag automatically captures errors and alerts you via email, Slack, PagerDuty, and more. You'll also see detailed error reports in your dashboard for faster debugging.

Integrate with your Laravel ecosystem

Bugsnag works well with your Laravel tooling — integrate with the application logger, or monitor your Lumen projects, too, with Bugsnag for Lumen.

Real-time alerts where you already work

Bugsnag automatically alerts you via Slack and PagerDuty when errors are detected. Select your alerting preferences to know when new errors, regressions, or spike in your error rate occur.

Proactively address software quality

Visibility into errors is only the first step. With two-way integrations and in-app workflow, you'll also make progress prioritizing bugs and moving them through your debugging process.

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.

Comprehensive Tornado 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.

Reproduce errors with environment data

Important diagnostic data is automatically collected on each error like the browser and version, OS, request, and React specific data. You can also send custom data if what we capture isn’t enough.

Automatically collected user activity

Efficiently reproduce errors with a timeline of user and system events leading up to each error, like clicks, console logs and errors, page load, and more.

Correlate errors with users

Looking at error counts alone won't give you a full understanding of an error's severity. Correlate errors with users to see how widespread an error really is.

Decrease noisy errors

Cross-browser error grouping, domain whitelisting, discarding errors from legacy browsers, and stripped out browser extension errors help to decrease noisy React errors and keep you focused on the ones that matter. Learn more JS monitoring best practices.
