Browsa, now on your Mac.

A calm, keyboard-first browser with a sidebar for your spaces, a panel for your tools, and room for the extensions and agents you already use. Native WebKit, open source, and free.

Download for Mac For developers

macOS 26 or later

All the little things, taken care of.

The parts you notice on day thirty, not day one. Each of them made by hand, and none of them in your way.

Every action has a shortcut, and they’re yours

Arc’s keys out of the box, or Chrome’s or Safari’s with one switch, and you can change any of them in Settings. ⌘K shows each one beside its command.

Spaces

Work and life keep their own tabs and colour. Swipe between them, or press ⌃1.

Pinning

Keep a tab for good. It stays put, and closing it just puts it to sleep.

Favourites

The handful of sites you live in, one click away in every space.

Downloads

In a panel beside the page, never a bar across it. ⇧⌘J

Ad blocking, built in

Ads and trackers are gone before the page draws. No extension needed.

Reader

Just the words and pictures, set in a calm column so you can settle in.

Clean links

The tracking tags stuck on the end of links come off before you open or share them.

Tabs that tidy up

Tabs you’ve left alone slip into the archive. ⌘Y brings them back.

Moving from Arc? Your spaces come too.

Bring spaces, pinned tabs, bookmarks and history from Arc or the browser you use now.

Private when you want it

Private tabs leave no history. Sites are asked not to sell your data, and Browsa can forget it all when you quit.

And as many windows as you like, sharing one library of spaces. On iPhone too, handcrafted for iPhone Duo.

See it move.

Thirty-six seconds of Browsa for Mac: the sidebar, Radar, Notes, and an agent planning dinner.

Make it yours, a switch at a time.

The Library holds everything you can add to Browsa: our own plugins, in two packs, and Chrome extensions we’ve tested. Open it from ⌘K.

Agent Pack

Radar finds your dev servers, Notes holds your feedback on pages, and Agents lets Claude Code, Codex or Cursor work through Browsa while you watch.

Privacy Pack

On from the start. Ads and trackers are blocked, cookie banners are declined for you, and tracking comes off links before pages load.

Chrome extensions, verified to work

1PasswordPasswords, passkeys and cards, filled for you.

uBlock Origin LiteBlocks ads and trackers, with no setup.

Dark ReaderDark mode for every website.

VimiumBrowse with the keyboard: press f to click any link.

JSON FormatterReadable, collapsible JSON in the browser.

Paper SnapshotCopy any part of a site into Paper as editable layers.

Google TranslateSelect text on any page to translate it.

Add any of these in one click. Most others from the Chrome Web Store run too, through a compatibility layer on Apple’s WebKit; the ones above are the ones we’ve tested. Names and icons belong to their owners.

A browser your agents can share.

Switch on the Agent Pack and add Browsa to Claude Code in one click. Codex, Cursor and other MCP agents get a line to paste. Then they can open pages, read them and test your work, in the browser you’re already signed in to.

In their own space. Agents work in an Agent space. Your window never switches to it unless you choose to watch.
Your tabs stay yours. In its own space an agent never stops to ask. Reading or using one of your tabs, or even seeing their list, asks you first.
Notes for both of you. Leave a note on a page and your agent reads it, replies and resolves it.
Stop, always in reach. At the top of the sidebar while an agent drives, and in the Agents panel.
