suprswitch — Google Account Switcher av Mohammad Hamza Suhail

suprswitch switches between your Google accounts with a single keystroke. Hold a key, press a number, and you're in your other account — in the tab you're already on, with no avatar menu, no new tab, and no waiting.

It works across every google.com app because it switches the account right in the page's URL — so even an app it has never seen just works, with nothing to set up per app.

WHAT YOU GET
• Keyboard-first — hold your modifier (Alt/Option, Control, or Shift) and press 0–9 to jump to that account.
• Instant and in place — it rewrites your current tab in under a second. No new window, no lost draft.
• Works everywhere on google.com — switch accounts in any Google app, including ones Google ships next, with nothing to configure.
• People, not numbers — it shows each account's name and photo (read on your device) so you switch by who, not by index.
• A default account — set one, and typing or bookmarking any Google link always opens the account you meant.
• Yours to configure — pick your shortcut key and whether accounts count from 0 or 1.

PRIVATE BY DESIGN
• No tracking, no analytics, no ads, no servers.
• Your account names and photos are read on your device and never sent anywhere.
• It runs only on google.com and asks for the minimum permissions it needs.

Free, with no account and no sign-up. Switch accounts the fast way.
