Squash is an open source exception reporting and bug analysis tool. It is a collection of client libraries that records exceptions in your code, and gives you the tools you need to analyze and fix the bugs that caused those exceptions. The main emphasis is finding someone who can take responsibility for the bug and notifying that user, keeping the signal-to-noise ratio very high.
For more difficult bugs, Squash has a suite of collaboration tools, like commenting, assigning, and resolving bugs. There are lots of other features: Squash can symbolicate iOS stack traces, de-obfuscate Java traces, and source-map JavaScript call stacks.
