Sentry

Sentry provides open source error tracking that gives you insight into every crash in your stack as it happens, with the details needed to prioritize, identify, reproduce, and fix each issue. Sentry offers a perspective that enables you to see which errors are doing the most harm to your business and help you understand how issues affect your bottom line. Sentry was conceived in 2010 with a simple aim of illuminating production application issues. It started as a tiny bit of Open Source code, and has since expanded to an incredible team and hundreds of contributors, and now support all popular languages and platforms. Each month we process billions of exceptions from the most popular products on the internet. Users and logs provide clues. Sentry provides answers.
