Every AI assistant sounds capable in chat, then falls apart the moment it needs to actually open a tab, log in, and click through. GreaseClaw neo fixes that: be more productive with agents doing browser work in parallel, learn faster as it opens tabs for you, and trust the output by watching in real time with instant replay when it's done. Not a headless driver with no real logins. Not a cloud browser on someone else's machine. Yours, local, and watchable.
We built the four things any agent needs to work in a browser. All shipped today.
An ultra-lightweight Chrome extension for your AI agents, signed into your accounts (Gmail, GitHub, X, your bank). They work in theirs, you keep yours.
Your agent gets compact page snapshots instead of raw HTML, and batches actions in one call. Fewer round trips, smaller bills.
Each agent works in its own tab. Fire off three tasks, keep browsing in yours.
See every agent live, replay any session later, and every action is logged on your disk.
Powered by MCP, the open standard for AI integrations
Step 01
Link GreaseClaw neo to Claude Code, Cowork, Cursor, or Codex via MCP. No config files, no CLI.
Step 02
Ask in your terminal or IDE. The agent opens tabs, navigates, clicks, and reads the web signed in as you. Watch it happen in real time.
Step 03
A cockpit dashboard on your new-tab page shows every agent working in parallel: which site, which tool, how many steps. Each runs in isolated, toggle-grouped tabs.
Step 04
Every run saves as a full-screen, scrubbable video. Rewind, find the mistake, and coach the agent for next time.
Every agent opens its own tabs to work in and never touches the ones you already have open. It cannot close the doc you are writing, cannot steer the tab you are actively using, cannot step on your live window. You keep working while it works next to you.
Session history, screenshots, replays, and settings are files on your disk. Nothing goes to a dashboard we own. Open source, top to bottom.
GreaseClaw neo is your secondary browser, built for agents. They browse here with your real logins, while your main browser stays yours for work.

Everything you need to know about GreaseClaw.
GreaseClaw is an ultra-lightweight, free open-source Chrome extension your AI agents drive using your logged-in accounts. Your AI opens its own tabs inside it, and you watch, approve, and audit every step from a dashboard on your new-tab page.
Yes. GreaseClaw is completely free and open source under the AGPL-3.0 license. You bring your own AI provider keys.
Any AI agent that supports MCP, which is essentially every serious AI coding tool today. Claude Code, Cursor, Codex, VS Code, Zed, and GitHub Copilot install with one click. Anything else connects with a URL.
Yes. Open GreaseClaw, click Connect on the Claude Code row in the MCP install board, and Claude Code has a browser.
Yes. Codex is supported through the same one-click install as every other harness. No config file editing.
Yes. Claude Cowork connects through the same one-click MCP install as Claude Code, Cursor, and Codex. Any agent that speaks MCP can drive GreaseClaw.
GreaseClaw runs entirely on your own machine. It is not a cloud browser and not a headless driver. Your logins, sessions, screenshots, and replays are local files, and nothing goes to a server we own.
A headless browser has no real logins, so agents never touch your actual accounts. GreaseClaw is a full browser signed in as you, so agents do real work, and you can watch every step live and replay it afterward.
Yes. BrowserClaw is now GreaseClaw — same browser, same project, new name. Nothing you installed stops working, and you do not need to download it again. You will still see the old name in a few places we have not caught up with yet, like the GitHub repository and the MCP server name.
Not required. GreaseClaw is an ultra-lightweight Chrome extension you install on macOS or Windows. If you also use GreaseClaw as your daily human browser, the two products live side by side.
Everything runs on your machine. Session history, screenshots, replays, and settings are files on your disk. Your logins stay in your browser profile, same as any browser you use. Nothing goes to a dashboard we own. Open source, top to bottom.
Yes. Every agent gets its own set of tabs, tracked separately. Codex and Claude Code can each work on their own tasks at the same time without stepping on each other.
No. Every agent opens its own tabs to work in and never touches the ones you already have open. It cannot close the doc you are writing or steer the tab you are actively using. You keep working while it works.
Yes, that is the point. Agents drive GreaseClaw using the sessions you already have, so they automate your real work instead of poking a sandbox with no context. Per-agent profile isolation is on the roadmap if you want to keep them apart.
Yes. Every session is saved as a scrubbable video. Rewind, spot the moment things went sideways, and give the agent a better instruction next time.
macOS and Windows. System requirements match Google Chrome or Safari.
Yes. GreaseClaw is fully open source. The source code lives at www.github.com/greaseclaw/greaseclaw.
Public APIs stop at the front door. GreaseClaw neo lets your agent do the work waiting behind sign-in — in its own tabs, while you keep yours.
