React is powerful, but unnecessary re-renders and stale closures causing UI glitches happens.
Catch visual bugs before your customers do.
We catch these visual regressions instantly
Infinite re-render loops freezing the browser
Stale variables (e.g. "effort" ref) not updating
Effect dependencies triggering unwanted side effects
"Unit tests often mock state, but they miss "Stale Closures" where a variable inside a function refers to an old value. Visual monitoring sees what the user actually sees."
Traditional uptime monitors only check if your server is responding (200 OK). They won't tell you if Stale State & Race Conditions made your site look broken to users.
We take screenshots of your React site periodically. If a pixel changes due to an update or code deployment, we alert you instantly via Slack, Email, or Telegram.
