AI browser-control tool

AgentLimb

AgentLimb is a universal web-control Chrome extension: any command-capable AI terminal — Claude Code, Codex, Cursor, Trae, Windsurf internationally, or Tencent WorkBuddy, Alibaba Qwen Office, ByteDance TRAE Work, Cola, and Kimi Work in China — can onboard with one prompt and operate the web through your real browser sessions. Since 0.2.1 (b7) it fully supports both Windows and macOS.

Platform
Chrome / Edge / Brave / Vivaldi / MCP / Windows + macOS / Local bridge
Status
Open source / 0.2.1 b7 / Local-first / Win + Mac
Audience
Developers and heavy AI users who need agents to work with real websites, logged-in sessions, and multi-account workflows.

Product Overview

AgentLimb positions itself as a universal web-control plugin for every platform and every AI tool. It is not tied to one vendor: any terminal that can run local commands drives the browser through the local Bridge and 16 standardized tools — locating elements, filling forms, clicking, screenshots, data extraction — all on your real, already-logged-in browser sessions. No headless browser, no re-login.

Version 0.2.1 (b7) is the dual-platform milestone: the same onboarding prompt works on both Windows and macOS. On macOS an already-installed Runtime starts instantly; on Windows install.ps1 registers the local service and autostart. Both platforms require explicit user approval and verify SHA-256 before download. The v0.1.4 Windows install gap (GitHub issue #2) was fully resolved by the v0.2.x two-package model.

b7 also announces official support for Chinese AI terminals: Tencent WorkBuddy, Alibaba Qwen Office, ByteDance TRAE Work, Cola, and Kimi Work. All five use the exact same onboarding protocol as Claude Code, Codex, Cursor, Trae, and Windsurf — copy the prompt from the side panel, paste it into the terminal, approve, and you are configured in 10 seconds. Combined with every Chromium browser (Chrome, Edge, Brave, Vivaldi), AgentLimb becomes a ready-to-use web-automation base for Chinese AI office scenarios.

Why It Matters

Each product page is written for users, reviewers, and builders: what it solves, what it does not solve, and what can be reused.

Works with Chinese AI terminals out of the box

WorkBuddy, Qwen Office, TRAE Work, Cola, and Kimi Work need zero special configuration — the same single onboarding prompt as international terminals. Chinese AI office suites get a properly adapted web-control capability for the first time.

Real sessions, not headless browsers

Agents operate the browser you actually use: logins, cookies, and multiple profiles all preserved. Logged-in sites work immediately; multi-account flows run in parallel.

Route memory that pays for itself

DOM exploration settles into human-readable muscle memory files, saving an average of 85.7% tokens on repeat tasks — especially valuable on usage-billed Chinese terminals.

Core Experience

One-prompt onboarding

Click Copy Onboard Prompt in the side panel and paste it into any AI terminal. After approval the terminal downloads the Runtime, verifies SHA-256, configures Native Messaging, and passes a health check.

Official Chinese terminal support

Tencent WorkBuddy, Alibaba Qwen Office, ByteDance TRAE Work, Cola, and Kimi Work are adapted via the standard protocol — no plugin-side changes needed.

Windows + macOS

b7 fully supports both systems: install.ps1 on Windows registers the local service; macOS starts an installed Runtime in seconds and only downloads on first run.

Every Chromium browser

The extension installs on Chrome, Edge, Brave, Vivaldi, and anything else that supports the Chrome extension system.

Muscle route memory

Each site's DOM structure and operation routes persist as human-readable JSON memory the agent reuses next time — saving tokens and time.

16 standardized tools

navigate, page_snapshot, javascript_eval, tabs_context and more, auto-discovered via /docs endpoints — no SDK preinstall for any agent.

Design Principles

Terminal-agnostic

No vendor-private capabilities — one open protocol, so new terminals are compatible by default.

Approval first

Downloads, installs, and every write action require explicit user approval; silence never equals success.

Local-first

Bridge, sessions, and memory files stay on 127.0.0.1 on your machine — no browsing data is uploaded.

Build Diary

The AgentLimb diary tracks the full path from browser extension, local Bridge, and dual-platform bootstrap to Chinese-terminal adaptation, doubling as a case study for the AI automation course.
