Case Study: How Rootly cut MTTR 50% with Sentry
Key results
The challenge
Rootly, an incident-response and reliability platform, needed rapid error detection across a globally dispersed engineering team deploying frequently to multiple cloud environments. It required full-stack visibility from its Ruby on Rails backend to web and mobile frontends to catch issues before user impact.
The solution
Rootly integrated Sentry from day one, adding tag-based categorization of business-critical versus informational issues, connecting alerts to its on-call platform, and enriching them with affected customer segments and deployment version data.
“We deploy 10-20 times a day—only possible with Sentry pinpointing issues down to the commit and broken line of code.”
