Nice! Not sure if you knew about it, but sentry does javascript, python, php, golang, and several other languages all with one super nice user interface. It was originally developed by disqus, but now spun off into a hosted version as well. The code is 100% open source and I suggest it to anyone with a serious production webapp.<p><a href="https://github.com/getsentry/sentry" rel="nofollow">https://github.com/getsentry/sentry</a><p><a href="http://getsentry.com" rel="nofollow">http://getsentry.com</a>
