Real-Time Alerts

Get alerted as soon as errors happen.

When errors happen in your application, you need to know instantly. Receive alerts through the communication tool your team uses, whether that is email, Slack, Discord, or another messaging platform.

Detailed Error Reports

Find the root cause of any error.

We save error details and provide you with the information to drill down to the root cause. Look at other occurrences of the same error to discover patterns. Tag errors with user ID's or anything else to make debugging easier, and add links back to your CRM to follow-up on affected users.
