The problem
Anyone who uses several accounts on the same website, whether personal and work accounts or client and test accounts, has to sign out, sign back in and remember passwords, or juggle between profiles and private windows.
CookieSwapper.
All your accounts. One browser.
An extension that remembers the session of each account on any website and lets you switch from one to another with a click. No signing out and no retyping passwords.
- Switch with one clickSaves each account's session under a label and restores it instantly.
- Open with another accountFrom the context menu, any link can be opened with the account you choose.
- Your sessions stay on your deviceThe extension works inside your browser and lets you export a backup copy.
The solution
An extension that saves each account's session per domain and restores it with one click, reloading the page already inside the other account. It works in Chrome, Edge, Brave, Opera, Vivaldi, Arc and other Chromium-based browsers.
Key decision
Keep the extension lightweight and dependency-free, with the sessions stored in the browser itself. The website and a small reports API complete the product.
