Veb brings Helium’s pinned and open tabs, passwords, cards, bookmarks, history, extensions and your sign-ins, from every profile.
Veb reads it straight from Helium’s files on your Mac. Nothing goes through a server, and Helium can stay open.

What changes after Helium
Veb next to Helium, area by area. The full comparison has the table and sources.
AIVeb leads
Only Veb has an agent that clicks, types and finishes tasks in your pages. Helium has no AI: Chromium’s Gemini features are taken out. Veb’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.
Agents like Claude Code and CodexVeb leads
Helium has no MCP server or command line for outside agents. Veb 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.
Tabs and windowsVeb leads
Helium has tabs down the side as a setting, Split View, folders in the sidebar and tabs that sleep. Veb has tabs down the side, spaces, Split View, folders in the sidebar and tabs that sleep.
PriceVeb leads
Helium: Free and open source. Veb: Free; its AI runs on your own Claude or ChatGPT plan.
Where it runsHelium leads
Helium runs on Mac, Windows and Linux. Veb runs on Mac. On a Mac, Helium needs macOS 13 or later and Veb needs macOS 15.4 or later. Helium has no phone app: desktop only. An iOS build teased in Aug 2026 is being rethought. On the phone, Veb: Veb for iPhone, in beta on TestFlight; syncs spaces, tabs, bookmarks, history and chats.
Engine and extensionsa matter of taste
Helium is built on Chromium, as Chrome is; Veb on WebKit, the engine Safari uses. Both take extensions from the Chrome Web Store.
PrivacyHelium leads
Helium has an ad blocker built in and open code. Helium makes no requests on first launch and has no analytics; updates, filter lists and extensions go through its services only once you approve. Veb has an ad blocker built in. Veb 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.
Questions
Does moving change anything in Helium?
No. Veb only reads Helium’s files. Helium keeps everything, and you can go on using both.
Do I have to close Helium first?
No. Veb reads Helium’s files while it is open.
Will I stay signed in to my sites?
Mostly. Your sign-ins come with the rest, so most sites open signed in. A few ask you to sign in again.
Do my extensions come?
Yes. Veb fetches each one you had switched on fresh from the Chrome Web Store and runs it on WebKit, the engine Safari uses. Most work as in Chrome; what an extension kept itself, like its own sign-in, stays in the old browser.
Can I bring it in again later?
Yes, any time, from Settings › General › Bring in from another browser.
What does Veb cost?
Nothing. Its AI runs on the Claude or ChatGPT plan you already pay for, if you connect one.
Veb, Very Expensive Browser.
Free for the Mac. Arc’s sidebar, your own Claude or ChatGPT as the agent, Chrome extensions on WebKit.
