Browser Use

Open-source Python framework making websites accessible to AI agents – the #1 browser automation project by GitHub stars.

Each tool is evaluated against our methodology using public docs, vendor demos, and hands-on testing.

Cloud browser infrastructure provides managed Chromium instances that AI agents can control remotely. These platforms handle the complexity of browser lifecycle management, anti-detection, session persistence, and scaling. They are used by AI agents that need to interact with authenticated websites, fill forms, or navigate complex multi-step web workflows.

Editorial assessment

78,000+ GitHub stars make this the most popular browser automation project in the world. The Python framework is clean and the ChatBrowserUse custom model is a smart move. Open-source framework ≠ production infrastructure. You still need to manage browsers, proxies, and scale. The Cloud offering fills this gap but competes directly with Browserbase.

How Browser Use compares

Browserbase

Browserbase provides the managed infrastructure that Browser Use's framework needs to run at scale.

Steel.dev

Steel.dev offers a managed browser API alternative to self-hosting Browser Use.

Frequently asked questions

Is Browser Use open source?

Yes. Browser Use is an open-source Python framework for making websites accessible to AI agents, and it is among the most-starred browser automation projects on GitHub with 78,000-plus stars. The core library is free to install and use. The company also runs a separate hosted Cloud product, but the framework itself stays open source and can be self-hosted on your own infrastructure.

Can Browser Use be self-hosted?

Yes. Because the framework is open source, you can run it locally or self-host it and connect your own LLM, including Anthropic, Google Gemini, or Browser Use's own ChatBrowserUse model. Self-hosting means you manage the browsers, proxies, and scaling yourself. The hosted Cloud option exists if you would rather not operate that infrastructure directly.

How much does Browser Use cost?

The open-source framework is free. The hosted Cloud has a free tier with three concurrent sessions, then paid plans: Dev at $29 per month, Business at $299, and Scaleup at $999, each granting matching monthly credits and higher concurrency. Enterprise pricing is custom. Annual billing removes about two months of cost (pay for 10, get 12). Confirm current numbers on the pricing page, since hosted tiers change.

Does Browser Use render JavaScript and handle dynamic sites?

Yes. Browser Use drives a real browser, so JavaScript-heavy and dynamic pages render fully before the agent acts. It also supports structured output, returning extracted data in defined schemas rather than raw text. The hosted Cloud adds stealth browsers and CAPTCHA solving for sites with anti-bot defenses, which the bare open-source framework leaves to you to configure.

What is the best alternative to Browser Use?

Browserbase is the closest alternative and the one Browser Use Cloud competes with most directly, since both sell managed browser infrastructure. Choose Browserbase if you want hosted browsers without adopting a specific agent framework. Steel.dev is another managed-browser option, and Stagehand suits teams who want a lighter automation layer. Pick Browser Use when you want an open-source Python agent framework you can self-host.

How does Browser Use compare to Browserbase?

They solve overlapping but different problems. Browser Use is primarily an open-source Python framework for building AI browser agents, with an optional hosted Cloud. Browserbase is infrastructure first: managed, scalable headless browsers you script against with your own tooling. If you want the agent logic and natural-language control built in, Browser Use fits. If you only need reliable hosted browsers under existing code, Browserbase is the more direct match.
