YabMove from Aside to Yab.

What changes after Aside
Yab next to Aside, area by area. The full comparison has the table and sources.
AIa matter of taste
Both have an agent that works in your pages. Aside’s agent runs multi-step tasks in your signed-in sites, signs in from its own password vault without seeing the passwords, and asks before payments, posts and messages. 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.
Agents like Claude Code and Codexeven
Aside can be driven over MCP and a command line, through the aside command line, with aside mcp as its MCP server. 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.
Tabs and windowseven
Both have tabs down the side, spaces, Split View, folders in the sidebar and tabs that sleep.
Priceeven
Aside: Free with 500 AI credits a month; Pro $20/month; Max $200/month; or your own ChatGPT or Claude plan. Yab: Free; its AI runs on your own Claude or ChatGPT plan.
Where it runsAside leads
Aside runs on Mac and Windows. Yab runs on Mac. On a Mac, Aside needs macOS 15 or later and Yab needs macOS 15.4 or later. Aside has no phone app yet: an iPhone app is in the works. Pro runs its agent from Slack or Telegram. Yab has no phone app yet.
Engine and extensionsa matter of taste
Aside is built on Chromium, as Chrome is; Yab on WebKit, the engine Safari uses. Both take extensions from the Chrome Web Store.
Privacyeven
Both have an ad blocker built in. Aside keeps task transcripts and files on your Mac; model providers get the prompts, page snapshots and screenshots a task needs, and analytics sharing is on by default. 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.
Questions
Does moving change anything in Aside?
No. Yab only reads Aside’s files. Aside keeps everything, and you can go on using both.
Do I have to close Aside first?
No. Yab reads Aside’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. Yab 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 Yab cost?
Nothing. Its AI runs on the Claude or ChatGPT plan you already pay for, if you connect one.
Yab, Yet Another Browser.
Free for the Mac. Arc’s sidebar, your own Claude or ChatGPT as the agent, Chrome extensions on WebKit.
