Arc

Arc is a web browser from The Browser Company that rethinks the traditional tab bar. Instead of one long row of tabs, Arc organizes browsing into Spaces (separate profiles for work, personal life, or side projects) and a vertical sidebar, with Split View for viewing two pages side by side and built-in tools like an ad blocker and screenshot tool. Arc is built on Chromium, so it supports the same extensions and sites as Chrome, while adding features like Boosts (custom CSS/JS tweaks per site) and Easels for quick notes and moodboards. As of its current site messaging, active feature development has shifted to Dia, the company's newer AI-first browser, while Arc itself continues to receive Chromium security updates.

Toby

Toby is a browser extension and companion app that turns an overwhelming pile of open browser tabs into organized, named collections. Instead of hoarding dozens of tabs, users save groups of links into Toby's visual workspace and close the tabs, then reopen a whole collection later in one click. It supports AI-assisted organization of saved tabs, instant search across everything stored, and a lightweight built-in to-do list alongside the link collections. Toby works across Chrome, Edge, and Firefox, plus a web app and mobile apps, and is used by both individuals and teams for shared project link libraries, reporting over 500,000 users.

Tab Deck

Tab Deck is a browser extension that pulls every open tab into a single sidebar panel so users can save, group, reorder, and restore tabs and entire sessions without hunting through a crowded tab strip. It adds a command-palette style fuzzy search, tab de-duplication, and one-click session restore into new windows.
