I built Sentry at Dropbox because I was tired of finding out about bugs from angry customer support tickets. By the time a user complains, 1,000 other users already hit the same error and left silently.
We changed our license from BSD to BSL and the open-source purists lost their minds. But the alternative was watching AWS offer Sentry as a service and collect the revenue. Pragmatism beats ideology.
Sentry catches over a billion errors per day. A billion. Every single one of those is a moment where someone's code broke and they need to know about it before their users do.
Our SDK takes 2 minutes to install. Your first error notification arrives 5 minutes later. If enterprise software took this long to show value, every SaaS company would be profitable.
Datadog added error tracking. New Relic added error tracking. Dynatrace added error tracking. We are not worried. When error tracking is your one thing versus their fifteenth feature, you win on depth every time.
The best developer tools spread the same way — one engineer adds it to a project on a Friday afternoon, the team sees value on Monday morning, and the company is on a paid plan by the end of the quarter.
