About

Page Performance Monitor is a lightweight developer tool that shows real-time rendering performance directly on any webpage.

When you click the extension icon, it displays an overlay containing:

• FPS (frames per second)
• Average / Min / Max FPS
• Frame time metrics
• Jank detection indicators
• JavaScript heap usage
• Runtime statistics

The monitor helps developers analyze animation performance, rendering stability, and runtime behavior while testing web applications or games.

The extension only runs when manually activated and does not collect or transmit any user data.

Keyboard shortcuts:
Alt + Shift + K → Show monitor
Alt + Shift + O → Remove monitor

Page Performance Monitor does not collect, store, or transmit any personal data.

The extension runs locally in the user's browser and only displays performance information from the currently opened webpage.

No browsing history, page content, or user information is transmitted to external servers.
