bug tracking


Crash detection and reporting are tough but important problems to solve, as companies look to increase the stability and reliability of their online and mobile applications. One newer startup taking on this challenge, Bugsnag, has already found traction in this space, having signed up a number of notable customers, including LinkedIn, Svbtle, and Kiipt, among others. Today, the company is announcing $1.4 million in seed funding in a round led by Matrix Partners.



Sentry is the most comprehensive parental control app. Mobile tracking, text and image analysis, usage monitoring and much more!
Open-source error tracking that helps developers monitor and fix crashes in real time. Iterate continuously. Boost efficiency. Improve user experience.


Rollbar is a full-stack error monitoring platform. Developers use it to find, reproduce, and fix bugs many times faster than legacy solutions (like digging through log files or responding to customer support issues).

It works by integrating into each part of the application: client (iOS, Android, JS) and server (Ruby, Python, Node, PHP, many others). This gives us code-level visibility on errors that happen in production. When an error is detected, our libraries collect a wealth of data about the error (e.g. which lines of code) and its context (e.g. which user was affected), and report it to our API. Then we analyze, de-dupe, send alerts, and prepare the data for further analysis by the developer.
