Headless browser cloud built for AI agents

Browserbase is cloud infrastructure that runs headless Chromium browsers on demand for AI agents and automation workflows, exposing Playwright, Puppeteer, and Selenium endpoints with built-in session replay, residential proxies, CAPTCHA solving, and stealth fingerprints. It also hosts Stagehand and a Model Gateway, letting teams build browser-using agents without maintaining their own fleet of Kubernetes-managed Chromium instances.

Microsoft's MCP server for structured browser automation by AI agents

Playwright MCP is Microsoft's Model Context Protocol server that enables AI agents to automate web browsers through structured tool calls. It exposes Playwright's browser automation capabilities as MCP tools for navigation, clicks, forms, extraction, and screenshots. The Microsoft-maintained repo has 30K+ GitHub stars and is a durable default for structured browser interaction in agent workflows.

Codeless browser testing with visual test recorder and scheduling

Ghost Inspector provides codeless browser testing through a visual recorder that captures user interactions and converts them into automated test suites. Tests run on managed infrastructure with scheduled execution, CI/CD integration, and Slack notifications. Features visual comparison for UI regression detection, API testing, and test organization with folders and tags for managing large test suites.

Browser automation CLI built for AI agents by Vercel Labs

Agent Browser is a Rust-based browser automation CLI designed specifically for AI agent workflows rather than traditional testing. Developed by Vercel Labs, it provides semantic element selection through a refs system, accessibility tree snapshots, session persistence, and authentication vaults. Unlike Playwright or Puppeteer which target test automation, Agent Browser optimizes for token efficiency and deterministic element selection that gives LLMs reliable browser interaction capabilities.

Zig-built headless browser engineered for AI agent workloads

Open-source headless browser written in Zig for AI agents, crawling, and automation. Lightpanda omits graphical rendering, keeps DOM and JavaScript execution, exposes CDP for Puppeteer/Playwright/chromedp, and adds Agent, PandaScript, and MCP workflows. Current public benchmarks claim about 9x faster execution and 16x less memory than Chrome.
