Honeybadger vs. Opbeat vs. Errorception

Honeybadger does more than report errors, it helps you work with your team to fix them. Errors can be assigned. You can comment via email. And a fine-grained permissions system means you control who has access to each specific project.

Opbeat is application monitoring for developers, and gives you performance metrics, error logging, release tracking and workflow in one smart product.

Errorception is a simple and painless way to find out about JavaScript errors, as they occur in your users' browsers. All you need to do is insert a script tag on your page, and you will start recording errors as they happen in real-time.
