As you deploy code more frequently and ship features faster, you still have the risk of a release going wrong that could turn your evening into an all-nighter. We’ve got you. We’ve built Feature Monitoring to detect issues in your release caused by a recent change, determine which feature caused the fault, alert the team responsible, and allow you to switch off the feature instantly. This is powered by new integrations with Sentry error tracking and a javascript performance monitoring agent. Page load times getting worse? Error rates rising? We’ll identify the change that caused it within 30 minutes. Tune in to hear how you can start monitoring your next release!
