# browser-agents

Open-source agentic browser that runs local AI agents in your browsing workflow.

BrowserOS is a privacy-first, open-source agentic browser for running AI assistants locally inside real browsing sessions instead of handing every task to a remote cloud browser.

Microsoft browser agent that turns long-horizon web tasks into reusable Playwright code

Webwright is a Microsoft browser-agent project that asks coding models to write, debug, and reuse Playwright scripts instead of relying on one-off stochastic click loops. The approach gives automation teams a more inspectable artifact: scripts can be logged, reviewed, rerun, and maintained like normal test or scraping code. It is especially relevant for long-horizon browser tasks where teams care about determinism, auditability, and resilience to UI changes.

Open computer-use platform for browser, terminal, and full desktop automation

Coasty is an open-source computer-use platform for teams that want AI agents to operate across browser, terminal, and full desktop surfaces instead of only clicking DOM nodes. The project combines planner/orchestrator logic, visual and input control, local Electron workflows, remote sandbox options, an MCP server, and logs for debugging long-running automations. It is a strong fit for QA, research-to-action, form workflows, and repetitive desktop tasks where browser-only agents are too narrow.

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.

AI-powered web browser automation with Playwright

Stagehand is an open-source browser-agent SDK from Browserbase that combines deterministic browser automation with AI primitives such as act(), extract(), observe(), and agent(). Instead of relying only on brittle selectors, developers can use natural-language actions, Zod-backed structured extraction, page observation, action caching, and Browserbase cloud-browser infrastructure for production web automation.
