Developer-first error tracking and performance monitoring
What it does
Sentry is a monitoring platform that automatically catches errors and performance problems in software applications the moment they happen, giving development teams a detailed picture of exactly what went wrong and why. It works across virtually every major programming language and platform, from mobile apps to websites, so teams can find and fix issues before customers are significantly impacted.
Why it matters for PMs
With over 43,000 stars and broad adoption, Sentry has become a go-to standard for software reliability, meaning teams using it can dramatically reduce the time it takes to diagnose and resolve outages — directly protecting user experience and revenue. For PMs and founders, this represents the growing market expectation that products must be proactively monitored rather than waiting for customers to report bugs, making tools like Sentry essential infrastructure for any serious software business.
