Echotab

About

Echotab lets you mirror your actions from one browser tab to another in real time. Open two tabs side by side, activate Echotab, and everything you do in one tab is instantly replicated in the other.

What it does:
When comparing two web pages - whether it's two versions of a design, a staging site vs production, or two similar documents - you normally have to switch back and forth, scroll each one separately, and try to keep your place. Echotab removes that friction by keeping both tabs perfectly in sync.

Features:
• Scroll - Both tabs scroll in lockstep. Scroll down on one page and the other follows, keeping both views aligned for easy comparison. Enabled by default.

• Clicks - Every click produces a visual ripple on the mirrored tab at the exact same coordinates, so you can see precisely where you're interacting on both pages.

• Cursor - A ghost cursor appears on the mirrored tab, following your mouse position in real time. Useful for pointing at specific elements across both pages simultaneously.

• Keystrokes - Keystrokes are forwarded to the mirrored tab. Type into a search box or form field and watch the same input appear on the other side - great for comparing search results or form behavior.

• Zoom - Sync zoom level across tabs so both pages stay at the same magnification.

• Navigation - Back/forward navigation is mirrored across tabs, so browsing through page history stays in sync.

• Sync All - Turn everything on at once with a single toggle.

Each feature can be toggled on or off independently from a compact popup. Lightweight, no data collection, no external connections - everything runs locally in your browser.
