YabTabbit vs Opera Neon
Tabbit is a free Chromium AI browser for Mac and Windows from Lumina Lab in Singapore, with chat, an agent mode and a choice of many vendors’ models.
Opera Neon is Opera’s agent browser for Mac and Windows. Its own agents act in your live session on a $19.90 plan, and since August 2026 outside agents like Claude Code can use it free through its MCP Connector.
The short answer
- if you want a free agent browser with a wide choice of models, Chinese ones included
- if you want the same AI browser on Windows and Mac
- if you want Codex or Claude Code to use your signed-in sessions through its command line
- if you want Claude Code or another MCP client to use a real signed-in browser, free
- if you want one plan for an in-browser agent, deep research and making apps and media
- if you want a VPN and an ad blocker built in
- 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

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.
AIa matter of taste
Both have an agent that works in your pages. Tabbit chats with your tabs, files and screenshots, and its agent mode runs multi-step tasks in tab groups of its own, on GPT, Claude, Gemini, DeepSeek, Kimi, Qwen or GLM. Neon Chat talks about your tabs, Neon Do acts in your live session, research agents dig, and Make builds apps and media on Opera’s servers.
Agents like Claude Code and CodexOpera Neon leads
Tabbit can be driven over a command line, through the Tabbit command line, with a skill for Codex, Claude Code and Cursor. Opera Neon can be driven over MCP and a command line, through its MCP Connector, read-only unless you allow more, and opera-browser-cli.
Tabs and windowsTabbit leads
Tabbit has tabs down the side, Split View and folders in the sidebar. Opera Neon has spaces.
Priceeven
Tabbit: Free with a weekly AI allowance; Pro $30/month. Opera Neon: Free, and free for outside agents; Opera’s own agents $19.90/month.
Where it runseven
Both run on Mac and Windows. On a Mac, Tabbit needs macOS 13 or later. On the phone, Tabbit: only for its Chinese edition, in Chinese; tabbit.ai lists mobile as planned. Opera Neon has no phone app yet: Opera says a mobile version will come, no date given.
Engine and extensionsa matter of taste
Both are built on Chromium, as Chrome is, so sites work as they do in Chrome. Tabbit takes extensions from the Chrome Web Store, Opera Neon none.
PrivacyOpera Neon leads
Tabbit has an ad blocker built in. Tabbit sends prompts and pages you share to the model vendor you pick, on servers in Singapore or your region; its maker says it doesn’t train on your data. Opera Neon has an ad blocker built in and a VPN. Page content used with Neon’s AI goes to Opera’s and OpenAI’s servers, kept up to 365 days; passwords, cards and cookies stay on your device.

Yab, honestly
