Typescript Runtime Adapter Development With Browser Injection

Make Any Website & Tool Your CLI. A universal CLI Hub and AI-native runtime. Transform any website, Electron app, or local binary into a standardized command-line interface. Built for AI Agents to discover, learn, and execute tools seamlessly via a unified AGENT.md integration.

Unique: Compiles TypeScript adapters to injected scripts executed within Chrome's runtime via CDP, providing full browser API access and complex state management; combines type safety of TypeScript with browser-native capabilities without requiring separate browser automation libraries

vs others: More powerful than YAML pipelines for complex sites; type-safe compared to raw JavaScript injection; avoids Puppeteer/Playwright overhead by reusing existing Chrome session instead of spawning new browser instances

Your browser is the API. CLI + MCP server for AI agents to control Chrome with your login state.

Unique: Two-tier adapter loading system (local ~/.bb-browser/sites/ + synced community ~/.bb-browser/bb-sites/) with domain-based discovery and metadata-driven argument validation. Adapters execute JavaScript within the authenticated browser context (Tier 3 injection), giving direct access to page internals, localStorage, and internal JS variables without external API calls.

vs others: Converts websites into APIs without requiring site cooperation or reverse-engineering, unlike web scraping libraries; community-driven ecosystem enables rapid adapter creation vs maintaining separate integrations for each platform
