Web agent SDK

A high-performance toolkit for deploying autonomous AI agents that navigate, extract data, and execute complex workflows across any web interface.

This SDK provides the essential infrastructure for building reliable web agents using headless browsers like Playwright or Puppeteer. It handles the heavy lifting (proxy rotation, fingerprinting, and CAPTCHA solving) so developers can focus on agent logic. By integrating with LLM frameworks like LangChain or CrewAI, the SDK allows agents to interact with DOM elements as if they were human users. It is built for scale: supporting thousands of concurrent sessions and providing session recording for debugging complex multi-step automations.
