Weavetab is the open automation engine for AI agents. It connects models directly to live Chromium browsers and Electron desktop applications via native Chrome DevTools Protocol (CDP) sockets — no WebDriver binaries, no cloud relay, zero telemetry.
Actions execute directly over local CDP sockets without external driver overhead. Web pages are translated into agent-readable semantic maps with turn-by-turn diffing that reduces token usage by up to 95%. Built-in security enforces local domain policies, role-based access control, and client-side credential injection.

Why not Playwright or Puppeteer?
The standard approach — Playwright over MCP — works. But it carries fundamental architectural costs that compound at scale.
| Playwright / Puppeteer | Weavetab | |
|---|---|---|
| Protocol layer | WebDriver BiDi or CDP via browser binary | Direct CDP WebSocket |
| Tool execution overhead | 50–300 ms (binary + IPC overhead) | In-process (direct local socket) |
| Desktop app control | Browser only | Chrome + any Electron app (Discord, VS Code, Figma…) |
| DOM representation | Full HTML dump to LLM | Semantic Map 3.0 with delta diffing |
| Token cost per map | ~2,000–8,000 tokens | ~80–400 tokens (95% reduction via delta) |
| CAPTCHA | API service required | Zero-API via CDP mouse physics |
| Credential safety | Secrets passed in plaintext | Blind Injection — never in LLM context |
| Extension access | Limited | Full Chrome Extension API surface |
