Localhost Port Manager

Scan, switch between, refresh, and close your active localhost dev tabs from one popup.

Localhost Port Manager helps developers who juggle multiple local dev servers keep track of them all in one place. If you regularly run more than one local server — a frontend on :5173, an API on :3000, docs on :8080 — you've probably lost track of which tab is which, or dug through a dozen open tabs just to refresh one server. This extension scans every open window for localhost and 127.0.0.1 tabs and gives you one popup to manage them from. FEATURES - Scan: automatically detects tabs matching localhost:* or 127.0.0.1:* (both http and https), across every open window - Jump to tab: click any entry to instantly focus that tab and bring its window to the front - Refresh All: reload every tracked dev server tab in one click - Close: close a single tracked tab directly from the popup - Rescan: manually re-scan if you opened a new localhost tab while the popup was already open PRIVACY This extension only requests permission to read tabs on localhost and 127.0.0.1 — no broad browsing history access is requested. Nothing is collected, tracked, or transmitted anywhere. Everything runs entirely inside your browser.
