SessionBox vs tabExtend

SessionBox One turns browser tabs into separate profiles so users can manage multiple accounts on the same site in one browser window. Profiles can use different proxies, and direct sharing lets someone pass along an active profile without sharing login credentials. Teams can share profiles and proxies through Shared Spaces. Cloud synchronization supports continuing sessions on another device, while a local API connects existing tools such as Selenium and custom solutions. The maker says sensitive profile data is encrypted and decrypted on the user's device using AES-256 and RSA 2048-bit algorithms. Local profiles are stored in browser IndexedDB, synced profile data in the maker's data store, and temporary profiles are not persisted. Extensions connect Chrome, Edge, Firefox, or Opera to the client application. SessionBox One is optimized for Windows and macOS; a mobile application is unavailable and not planned. The first installation starts a seven-day trial with all features and no credit card required. Hobby costs $4.99 a month.

tabExtend is a visual tab manager that adds notes, images, and reminders inside the browser. Users can save, close, and reopen groups of tabs with drag-and-drop or right-click actions. It also supports to-dos, colored notes, and reminders for sites and items. Workspaces and categories can be shared privately or publicly, with colleagues invited to collaborate in real time. Workspaces sync to the cloud for use across devices; tabExtend says its stored data is end-to-end encrypted and backed up twice a day. Search helps locate saved items, and groups can be generated from bookmarks and most-visited sites. The extension is available for Chrome, Brave, and Edge, with native apps for Android and iPhone/iPad. The free plan includes basic features and up to 30 saves, with unlimited time and no account required. Pro is $8 a month; Team is $21 a month for three seats, with additional seats at $7 each. The extension can replace the new-tab page and read browsing history; downloads, most-visited URLs, and bookmarks are optional permissions.
