Man, AppSignal is an absolute godsend. Just fixed 2 errors in production, 2 minutes after they happened.

AppSignal your "What Happened Here?" feature is pure gold. Just turned what would have been hours of debugging into minutes. I love you.

AppSignal that moment when I can hit up a client telling them about their error before they even submit a ticket. Thanks for being awesome

Pay for requests. Simple & affordable.

Our pricing is simple: we charge you for the requests we are monitoring for you. And yes, that means unlimited hosts, errors, applications, metrics and team members. The first 30 days are on us, no matter how much requests you send us!

So, what is a request?

A request is any background job or controller action that is executed. Eg. an hourly job generates 720 requests per month. Web requests depend on your traffic, but we don't count assets, cached resources and things like that.

Control your requests

It's easy to ignore specific actions and limit the number of requests you send us. This is useful if you don't care about monitoring some high-volume, low-importance parts of your app.
