Rollbar actually wasn&#x27;t inspired by Sentry -- it was inspired by our founding team&#x27;s efforts to solve exception tracking internally at Lolapps.<p>Several of the new features in Sentry (like release management &#x2F; deploy tracking) actually look a lot like things that have been in Rollbar for a long while, though I expect that is the result of two smart teams attacking the same problem, rather than one inspiring the other.
