Powerful Rails Error Monitoring
Built to monitor and track Rails errors on apps of all sizes, Bugsnag surfaces valuable information that helps you deliver high quality products to your users.
Get started with ease
Setting up error monitoring with Bugsnag is as easy as installing the Bugsnag's Ruby gem. It takes less than a minute to integrate into your Rails application.

Rails error report
Understand the root cause of errors
When errors occur, Bugsnag gives you a range of context about the event, like where and when the error happened and details about your affected users, helping you reproduce errors and pinpoint the source of the issue faster.
Keep track of all your Rails tools
Bugsnag ships with integrations already included for Rake, Rack, Resque, Sidekiq, and DelayedJob, giving you extra context about jobs that fail and where your errors were generated.
Rails errors grouped by root cause
Insights you can act on
Keep your team focused on fixing the issues that matter most with powerful workflow and prioritization tools.
Filter out the noise
Focus on errors that matter with full-text error search and precise error grouping. Sort your errors to find the ones that occur most frequently or that have the greatest impact on your users.
Error workflow status
Error alerts in Slack
Notify your team instantly
Keep a close watch on your Rails app from places like Slack, HipChat, and Gitter, or with email and SMS notifications. Automatically create tickets in JIRA, GitHub Issues, Pivotal Tracker, and more when a new error is found.
Get down to work
Code included with the full stacktrace helps your team diagnose errors quickly from within your Bugsnag dashboard. Assign errors to the right people on your team, discuss what's happening, and stay informed of how errors are progressing from new to resolved.
Rails stack trace
Level up your error handling
Powerful features like releases, sessions support, and full-stack monitoring mean you can rely on Bugsnag for all your unhandled exceptions
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.
Track errors by deployment
Bugsnag tracks deploys of your Rails apps on Heroku, Capistrano, and more. By sending the source revision or application version, you'll be able to see which release introduced an error and the diff where there's bad code.

JavaScript install with script tag
Go full-stack
With Bugsnag, you can also monitor Javascript errors alongside your Rails app. Get set up with a single script tag that enables cross-browser error grouping, browser and OS breakdowns, code snippets, and source map support, all to help you make sense of crashes. Learn more about our product.
