Arc spaces, one click
reads the sidebar Arc keeps on this PC, read-only, and rebuilds it: spaces with their colours and icons, pinned tabs and folders. Nothing is uploaded and nothing in Arc changes.
The browser after Arc
Free for Windows. Spaces, tabs you can tell apart and an ad blocker built in. Your Arc spaces come over in one click. No account, no telemetry.
Moving out of Arc
Or from any browser
Chrome, Edge, Brave, Firefox and Safari: bookmarks and history in one click. Passwords come in from the CSV file they export.
Arc stops on December 22
The Browser Company ends Arc on December 22, 2026. There is time to move at your own pace.
58 days left
Tabs you can tell apart
Every tab shows its title and its own close button, so three videos from one site are three different tabs. Spaces sit in the top bar as pills, each with its own colour.
- Drag to reorder, drop on the icons to pin
- Folders become groups you can fold
- Prefer Arc's vertical sidebar? One setting away
- Peek: Shift+click any link to open it over the page
- Boosts: your own colours, fonts and CSS for any site
Ad blocker built in
Lo-fi beats to code to
Everything on board
Ad blocking, built in
On from the first launch, YouTube included. Ghostery's open engine with uBlock Origin lists. Allow a site in one click.
Passwords, saved and filled
Sign in once and it offers to save, encrypted with your system's keychain. It fills only on the site it belongs to.
Chrome extensions
Add to Chrome from the Web Store. You see what an extension can do, in plain words, before it goes in.
Command bar
Press Ctrl+T to search, open a site, jump to a tab or run an action.
Mini player
Music in another tab gets play, pause and picture in picture right in the top bar.
Now playing
Private spaces
A space that saves nothing: no history, no cookies after you close it, no extensions.
Back after a crash
Tabs come back with their history, scroll position and even what you were typing.
Light on memory
Tabs you have not looked at go to sleep, and today's tabs archive themselves after 12 hours.
History and downloads
Searchable history by day, and downloads you can pause, resume and retry.
AI that does the work
Off until you switch it on. Then pick what runs each feature: a model on your own PC, or Claude.
Local model
Runs through Ollama on this computer. Nothing leaves your PC.
Your Anthropic API key
Claude on your own API account, key kept in the system keychain.
Your Claude Code plan
Personal builds can use the Claude Code already signed in on your PC.
Do it for me
Tell the agent what to do on the page you are looking at, like filling in a form or collecting every address on a page. It reads, clicks and types, and shows each step. Payments always wait for your click, and you can stop it any time.
- Read the page
- Typed the name
- Typed the city
- Done. The form is filled in; nothing was sent.
Draft a reply
In a mail or chat box, press Ctrl+Shift+Space. It writes in your voice and leaves it for you to send.
Better search
Press Tab in the command bar for a sharper search, or ask and get the answer right in the bar.
Ask about a page
Ctrl+J gives you the gist of a long page, or answers a question about it.
Tidy tabs
It suggests groups for today's tabs. Nothing moves until you apply.
Claude Code takes the helm
Turn on Settings › Claude Code and runs a local MCP server on this PC. Claude Code can then open tabs, read pages, click and type, in its own Claude space or in tabs you share with it.
Run once in a terminal
- Its own spaceOr only the tabs you share with it.
- Your click for paymentsAlso for sending and deleting, if you want.
- No secrets typed by AIPasswords and card numbers stay out of reach.
- Watch or stopA pill in the top bar, any time.
A browser, not a service
- No accountNothing to create, nothing to sign in to.
- No sync serverYour tabs never pass through a server of ours.
- No telemetryNo analytics and no usage tracking.
- Encrypted where it mattersPasswords and an API key use your system's keychain.
Your spaces, tabs, passwords and settings stay on your computer. Imports only read your other browsers' files, and private spaces write nothing to disk.
Questions
Is it free?
Yes. is free and there is no account to create. If you choose Claude with your own API key, Anthropic bills your API account directly; the local model costs nothing.
Is it open source?
Yes. The source is published under the GNU GPL v3 (or later): you can read it, build it yourself and change it, and versions others share stay open too.
Which operating systems does it run on?
Windows first. The installer is built and goes up here once it is signed. Other systems are not supported yet.
What comes over from Arc and my old browser?
From Arc: your spaces with their colours and icons, pinned tabs and folders. From Chrome, Edge, Brave, Firefox and Safari: bookmarks and history. Passwords come in from the CSV file those browsers and password managers export. Every import only reads; nothing in the other browser changes.
Do Chrome extensions work?
Yes, Manifest V3 extensions from the Chrome Web Store install with Add to Chrome and update on their own. A few Chrome-only features may not work yet.
Can I keep a vertical sidebar like Arc?
Yes. Settings › General › Layout switches between the top bar with tabs and the classic sidebar, any time.
Does it sync between devices?
No. There is no account and no sync server. Your spaces, tabs and settings live on your PC.
Do I have to use AI?
No. AI is off until you turn it on in Settings, and you choose which engine runs each feature.
Get for Windows
Free. No account. Your Arc spaces in one click.
Windows installer coming soon
The installer is built and is being signed. Arc keeps working until December 22, 2026, so there is time to switch.
