Be alerted to bugs immediately

Receive Slack notifications about problems immediately upon new release. Kuoll smartly merges JavaScript errors by stack traces.

Triage bugs in minutes

Kuoll dashboard shows how many users are affected by specific bugs. Understand the impact of each bug within minutes of new release.

Debug-friendly user sessions

Each Slack bug notification includes a link to a replayable user session. The session shows the record of 1) how user interacted with the web page, and 2) how the code was running on the end user machine. This is the same information which is available in the web browser developer's tools. Kuoll is like a time machine which allows the developer to see and investigate what went wrong on the user machine at the moment when a problem occured.

Kuoll crushes costs of bug fixing at all stages
