Need recommendations of an exception tracking system : <p>We need a recommendation for tracking exceptions in our web app. Our front-end is using Angular 1 or 2, back-end is using ColdFusion. We found <a href="https://bugsnag.com/" rel="nofollow">BugSnag</a>, but this company cannot do annual billing. </p>

<p>Does anyone know any other similar product?</p>

<p>Thanks a lot!</p>
