YabYab, Yet Another Browser, is a free Mac browser that keeps everything from Arc (tabs down the side, spaces, folders, Split View) and gives your Claude or ChatGPT plan an agent that works in your signed-in tabs.
Brave is an open-source Chromium browser that blocks ads and trackers by default, with Leo, an AI chat that needs no account, on every desktop and phone.
The short answer
- 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
- if you want ads and trackers blocked by default
- if you want AI chat without an account, or on your own local model
- if you need the same browser on every desktop and phone

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.
AIYab leads
Only Yab has an agent that clicks, types and finishes tasks in your pages. Yab’s agent works in tabs of its own beside yours, signed in as you, on your Claude or ChatGPT plan; Send, Pay and Delete wait for your yes. Leo chats about your tabs, PDFs and images, with no account, on Brave’s models or your own; an agent is in early testing behind a flag, in a separate profile without your sign-ins.
Agents like Claude Code and CodexYab leads
Yab can be driven over MCP and a command line, through yab mcp and the yab command, for Claude Code, Codex, Cursor and any MCP client. Brave has no MCP server or command line for outside agents.
Tabs and windowsYab leads
Yab has tabs down the side, spaces, Split View, folders in the sidebar and tabs that sleep. Brave has tabs down the side as a setting, Split View, folders in the sidebar and tabs that sleep.
Priceeven
Yab: Free; its AI runs on your own Claude or ChatGPT plan. Brave: Free, with Leo; Leo Premium $14.99/month; Brave VPN $9.99/month.
Where it runsBrave leads
Yab runs on Mac. Brave runs on Mac, Windows, Linux, iPhone and Android. On a Mac, Yab needs macOS 15.4 or later and Brave needs macOS 13 or later. Yab has no phone app yet. On the phone, Brave: iPhone, iPad and Android; syncs tabs, bookmarks, passwords and history, no account.
Engine and extensionsa matter of taste
Yab is built on WebKit, the engine Safari uses; Brave on Chromium, as Chrome is. Both take extensions from the Chrome Web Store.
PrivacyBrave leads
Yab has an ad blocker built in. Yab has no account and no server of ours between you and your sites; what your agent reads goes to Anthropic or OpenAI under your account. Brave has an ad blocker built in, a VPN and open code. Brave says Leo doesn’t keep or share chats, doesn’t train on them and doesn’t collect identifiers like IP addresses.
Where Brave is better
Brave comes out ahead on where it runs, privacy. It is also the better pick if you:
- Want ads and trackers blocked by default
- Want AI chat without an account, or on your own local model
- Need the same browser on every desktop and phone
The catch with each
Real limits, from the makers’ own words and our own use.
Brave
- More Leo models and higher limits need Leo Premium at $14.99 a month
- Its AI agent is an early test behind a flag, without your sign-ins
- The VPN is $9.99 a month extra
- Tabs down the side are a setting, and there are no spaces
Yab, honestly
- Mac only: macOS 15.4 or later, no Windows, iPhone or Android
- New: first released in September 2026
- Its AI needs a Claude or ChatGPT plan; ChatGPT’s free plan may work with low limits
- WebKit, as in Safari: a site tested only in Chrome can misbehave
- Closed source
