Overview
Description

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.

OneTab is a browser extension that converts all of a user's open tabs into a single, organized list with one click, freeing up memory and cutting down on browser clutter. Tabs can be restored individually or all at once later, and lists can be organized into folders, exported, or shared as a web page without ever transmitting URLs to OneTab's own servers.

Pros & Cons
Pros
  • Tab and Space organization meaningfully reduces browser clutter for heavy multi-tasking users
  • Split View and Easels add real productivity tools most browsers lack natively
  • Free to use with no account required for core features
  • Full Chromium compatibility means existing Chrome extensions still work
  • Dramatically reduces browser memory usage from many open tabs
  • Completely free with no account required to use
  • Works across Chrome, Firefox, Edge, and other Chromium browsers
  • Privacy-focused design that keeps tab data local unless sync is enabled
Cons
  • Active feature development has shifted to the company's newer browser, Dia, with Arc now getting mostly maintenance updates
  • No Linux version
  • The unconventional layout has a learning curve for users coming from traditional tab bars
  • Only manages tabs within a browser, not a full task or bookmark manager
