Arc is The Browser Company’s Chromium browser for Mac and Windows that put tabs down the side, with spaces, folders and Split View. It has had no new features since May 2025; it still gets security fixes, and its makers point people to Dia.
Edge is Microsoft’s Chromium browser on every desktop and phone, with Copilot built in. Since Copilot Mode was retired in May 2026, its agent, Browse with Copilot, comes with Microsoft 365 Premium in the US.
The short answer
- if you use it today and want its sidebar, spaces and Split View exactly as they are
- if you want a free browser with no paid AI plans
- if you need the same layout on Windows
- if you use Microsoft 365 and want Copilot in the browser
- if you want tabs down the side, workspaces, split screen and sleeping tabs built in
- if you work on Windows with Edge set up by your company
- if you miss Arc and want spaces, pins and folders kept, on a Mac
- if you already pay for Claude or ChatGPT and want it to work in your signed-in tabs
- if you want Claude Code, Codex or Cursor to drive a real browser over MCP

Where they differ
What separates them, area by area. Where one plainly has more, it says who; where it comes down to taste, it says so.
AIEdge leads
Only Edge has an agent that clicks, types and finishes tasks in your pages. Arc Max helpers tidy tab titles and downloads, preview links and put ChatGPT in the command bar; Ask on Page was removed in August 2025, and there is no agent. Copilot reads the page, your tabs and history and sums up videos and PDFs; Browse with Copilot scrolls and types in pages for you, signed in, on Microsoft 365 Premium in the US.
Agents like Claude Code and CodexEdge leads
Arc has no MCP server or command line for outside agents. Edge can be driven over MCP and a command line, through Microsoft’s Playwright MCP, which can launch Edge or attach to your running Edge.
Tabs and windowsArc leads
Arc has tabs down the side, spaces, Split View, folders in the sidebar and tabs that sleep. Edge has tabs down the side as a setting, spaces, Split View, folders in the sidebar and tabs that sleep.
PriceArc leads

Engine and extensionsa matter of taste
Both are built on Chromium, as Chrome is, so sites work as they do in Chrome. Both take extensions from the Chrome Web Store.
PrivacyEdge leads
Arc has no ad blocker of its own. Arc needs an account; The Browser Company says it doesn’t see which sites you visit, and Arc Max sends page data to OpenAI and Anthropic. Edge has a VPN. Copilot may use your question, the page, your open tabs and history; Browse with Copilot keeps screenshots up to 30 days, not for training, Microsoft says.
