A managed web API that lets agents browse the live web without running headless Chrome. /extract turns pages into Markdown or structured JSON, /generate transforms content on the fly, and /automate clicks, scrolls, and fills forms. Lightweight fetches escalate to full browser automation only when a site needs JS execution.

Pros & cons

  • Single API for extract, generate, and automate
  • Markdown/JSON output tuned for LLM context
  • Open-source engine (Pilo, Apache-2.0)
  • Free tier with 10,000 credits
  • Hosted service is proprietary (only the engine is OSS)
  • Credit-based pricing can be hard to forecast
  • Newer entrant vs. established browser-infra players

    Browserbase

    Browserbase

    Headless browser infrastructure for AI agents.

    Managed cloud fleet of headless browsers that let AI agents browse, authenticate, and act on the web at scale. Sessions ship with stealth proxies, automated CAPTCHA solving, and observability, driven via API or the open-source Stagehand framework. Usage-based billing on top of a monthly base plan.

    Hyperbrowser

    Hyperbrowser

    Cloud headless-browser infrastructure for AI agents.

    Managed cloud platform that gives AI agents scalable headless browser sessions with built-in stealth mode, proxy rotation, and CAPTCHA solving. Sessions launch in under a second and are driven via API with Playwright, Puppeteer, or Selenium. It also offers HyperAgent, an open-source framework that extends Playwright with natural-language commands, and an official MCP server so LLMs like Claude can browse the live web.

    Firecrawl

    Turn any website into clean, LLM-ready data — scrape, crawl, search.

    A web data API for AI — scrape, crawl, map, and search pages into clean markdown or structured JSON, handling proxies, anti-bot, and JS rendering for you. Open-source core (AGPL) plus a hosted service; a default web-ingestion layer for agents and RAG pipelines.

    Stagehand

    Browserbase

    Open-source SDK for building reliable AI browser agents.

    Stagehand is an open-source (MIT) SDK from Browserbase for building browser agents in TypeScript or Python. It exposes act(), extract(), and observe() primitives so you can drive a page with natural language while keeping deterministic code wherever you need it. v3 dropped its hard Playwright dependency for a modular Chrome DevTools Protocol driver.
