Launch HN: Meticulous (YC S21) – Catch JavaScript errors before they hit prod

Hey HN, I'm Gabriel, founder of Meticulous ( https://www.meticulous.ai ). We're building an API for replay testing. That is, we enable developers to record sessions in their web apps, then replay those sessions against new frontend code, in order to catch regressions before the code is released. I was inspired to start Meticulous from my time at Dropbox, where we had regular 'bug bashes' for our UX. Five or six engineers would go to a meeting room and click through different flows to try to break what we built. These were effective but time consuming—they required us to click through the same set of actions each time prior to a release. This prompted me to start thinking about replaying sessions to automatically catch regressions. You can't replay against production since you might mutate production data or cause side effects. You could replay against staging, but a lot of companies don't have a staging environment that is representative of produ
