Qbaka - a service for tracking JS errors

Petersburg developers Andrei Mima ( amima - ex-Yandex, ex-VKontakte) and Daniil Gitelson ( meta4 ) launched Qbaka service, whose task is to help programmers of sites and applications in tracking errors in JavaScript code. The service is still in beta testing , but it is already open to all comers.

The service is extremely simple to use: the programmer adds a few lines of JS code to his web application — they asynchronously load the Kubaki kernel, which collects errors (listening to window.onerror ) and sends them to the server.

To simplify the search for errors, the following information about the user is collected: browser, operating system, time zone, IP address. It is also possible to explicitly specify the identifier of the current user.

There is also a simple API that allows you to log exceptions manually:

  try { /* do something */ } catch (e) { qbaka.reportException(e); } 

')
The service provides an opportunity to share the project between several users, which can be useful if one service is developed by a group of developers.

At the moment, Qbaka is free and will remain so until mid-July, each account is limited to 30,000 errors per day. In the future we plan to introduce several different paid tariffs and limited free accounts.
