Overview
Browserbase is a developer platform that provides headless browser infrastructure and cloud execution environments built specifically for autonomous AI web agents. It solves the hardest challenges of automated browser interactions—including fingerprinting management, bot-detection evasion, CAPTCHA solving, session persistence, and full visual debugging. As AI agents transition from text chat to acting directly on the web, running local browser instances quickly breaks down due to scaling limits and anti-bot blocks. Browserbase provides a scalable serverless fleet of stealth Chromium browsers that agents can pilot via Playwright, Puppeteer, or Stagehand. Trusted by AI startups and enterprise automation teams, Browserbase enables developers to build reliable web scraping pipelines, automated booking assistants, competitor monitors, and end-to-end workflow bots.
Browserbase includes Session Replay, which automatically records video, DOM state, network waterfalls, and console logs for every automated browser run. This allows developers to visually inspect exactly where and why an AI agent took a wrong turn or got stuck. The platform also provides Stagehand—an open-source AI web automation framework created by Browserbase that allows agents to find elements and perform complex actions using natural language instructions (e.g. `page.act('click on the cheapest flight')`) with self-healing selectors.
Relevance AI is a platform designed to create AI workforces by combining LLM agents, tasks, and data pipelines. It provides an intuitive low-code workspace to build autonomous agents that execute multi-step operations.
Established in Sydney, Australia, Relevance AI supports multiple foundation models and complex state management features.
