MirrorTab is a Chrome extension designed for real-time mirroring of DOM interactions between browser tabs. It captures user actions such as clicks, inputs, and scrolling from a source tab and replicates them instantly on a target tab. This functionality is particularly useful for quality assurance testing, live demonstrations, and automated regression testing. Users can easily manage sessions through a popup interface, allowing for seamless interaction between the two tabs. Additionally, the extension supports session export, enabling users to save their recorded interactions for future playback or analysis.

The extension features a standalone replay engine that allows users to upload previously recorded session logs for automated playback on any desired environment. With adjustable playback controls and a visual ghost cursor to indicate the actions being mirrored, MirrorTab enhances user experience and efficiency. The extension maintains privacy by ensuring that all session data remains local to the user's browser, with no external data transmission.
