CrossSession Sandbox is a versatile Chrome extension designed for users who need to manage multiple accounts seamlessly within a single browser profile. With its multi-account sandboxing feature, users can create unlimited isolated browsing environments, allowing simultaneous access to various accounts on the same website without the hassle of incognito windows. The smart domain switching capability remembers sandbox preferences for each site, making account swapping instant and efficient.

In addition to its account management features, CrossSession Sandbox includes advanced developer tools for bypassing CORS restrictions, which simplifies API testing and debugging. Users can enable CORS bypass on specific sandboxes, addressing common scenarios such as standard CORS issues and iframe embedding. The extension also features an auto-destruct timer for temporary sessions and maintains a privacy-centric approach by storing all settings locally under a Zero Knowledge policy.
