Get notified the moment something breaks - shippingszn launch readiness

Error monitoring is software that sits inside your app and silently records every error, then alerts you. So when your user hits a bug at 2am, you know about it within minutes — instead of hearing about it three days later from a frustrated tweet.

Most users do not report bugs. They just leave. By the time you find out something is broken from feedback, dozens of people have already bounced. With error monitoring, you see problems immediately and can fix them before they spread.

The shippingszn CLI includes automated checks for this launch-readiness control.

The Launch Fix Kit keeps scan-specific findings, file and line evidence, AI-builder punch-list tasks, and verification steps tied to the paid report.

Sign up for Sentry (most popular, generous free tier), Rollbar, or PostHog.
Install their SDK in both your frontend and backend (your AI builder can do this in one prompt).
Connect it to email or Slack so new errors notify you.
For the first week after launch, check the dashboard daily — fix recurring errors before they pile up.
Configure it to ignore known noise (browser extensions, bots) so real signal stands out.
