Error Tracking
Catch errors and don’t let them happen twice.
Exception tracking is essential to every app. AppSignal provides all the alerts and insights you need to get errors under control. Stop playing whack-a-mole, start using AppSignal.

Real-time alerts
Get real-time alerts where your team works. Fix issues before your customers even notice them.
Deep debugging data
No more guesswork: AppSignal automatically collects all the data you need to debug errors.
Simple workflow
Leave comments in the logbook, send issues to GitHub, set severity levels, track progress, and more.
Real-Time Alerts
Get alerted as soon as errors happen.
When errors happen in your application, you need to know instantly. Receive alerts through the communication tool your team uses, whether that is email, Slack, Discord, or another messaging platform.

Detailed Error Reports
Find the root cause of any error.
We save error details and provide you with the information to drill down to the root cause. Look at other occurrences of the same error to discover patterns. Tag errors with user IDs or anything else to make debugging easier, and add links back to your CRM to follow up on affected users.

What our customers think
1500+ development teams rely on AppSignal to ship code with confidence. We are sharing a few of their stories with you.
Previously, we were using Honeybadger, Skylight, and Datadog, but now we have all those apps in one: AppSignal, and that is awesome!
Oleg, Developer at Benuevo
Hey y’all, we’re back. Sentry was just chaos.
Matt, Developer at Supertape
The biggest benefit of using AppSignal is the native Elixir support. … AppSignal just knows how an Elixir app is structured and builds error tracking and performance monitoring around it.

We looked at Sentry, Datadog, and Honeybadger. AppSignal gave us everything in one tool for a fraction of the price.
Thilo Rusche, Developer at SportsKey
In New Relic, if you want more features, you have to upgrade… AppSignal’s pricing was easier to understand, and you get all the features for one price.
Devan Sabaratnam, Co-founder & CTO at HR Partner
Second to none support. It’s their developers themselves who are quickly and clearly answering any questions. It’s hard to overstate how nice this is.

Rule Out Other Causes
Is your host causing errors?
Sometimes issues are caused by your hosts running amok. That’s why we keep track of host metrics for each error sample. Discover when to optimize your infrastructure before blaming lines of code.

Jam-packed
Everything you need to resolve errors.
AppSignal is jam-packed with features that give you deep insights into your application’s errors. And we’re adding new ones all the time!
Background jobs
AppSignal tracks errors in all major background processors for Ruby such as Delayed job, Resque, Sidekiq. Plus your custom background job processors.
Link templates
Link directly from issues in AppSignal to your own systems by creating custom URLs (i.e. link to your admin panel based on a user ID).
Parameter filtering
Your data is safe in our European data centers. But, we’d still rather not receive any private data. We offer extensive options to filter sensitive data from ever being sent from your app.
Tag errors
Tag your errors with additional information to get deeper and more detailed insights in what’s causing them.
Ignore actions
Want to prevent noise and exclude specific endpoints and jobs from being reported to AppSignal? Ignoring actions you care less about is easy.
