Overview
Browser Use is an open-source browser automation Agent framework, with the core positioning of "enabling LLMs to navigate and execute tasks on the web." It quickly surpassed 50,000 stars on GitHub and is one of the most popular open-source Web Agent infrastructures among developers in 2026.
Built on Playwright, it structures the web page DOM and feeds it to the LLM, allowing the model to output instructions like "click/input/scroll/navigate" and execute them. Developers can use a few lines of Python code to let Claude/GPT/Gemini autonomously operate the browser, serving as an open-source alternative to commercial products like Skyvern.
**📌 2026 Update**: Browser Use's GitHub Stars have grown from 50,000 to **60,000+**, making it one of the most active projects in the open-source browser Agent space. Recently, it has formed a complementary ecosystem with browser tools like **Playwright** and **Chrome DevTools MCP** (officially open-sourced by Google in May 2026). Developers can use Browser Use for complete browser automation Agents and Chrome DevTools MCP for debugging and inspection. The combination of the two is the standard setup for AI Agent + browser direction in 2026.
Key Features
- LLM-driven browser: Any LLM (GPT/Claude/Gemini) drives Playwright to operate the browser
- Structured DOM fed to the model: Extracts web page elements into structured data, reducing the difficulty for LLM understanding
- Python native API: Start a Web Agent with just a few lines of code
- Visual + text dual modality: Supports screenshot + DOM dual input
- Open source and customizable: Fully open source, can be modified/extended
- Multi-tab support: Can manage multiple tabs simultaneously
Use Cases
- Developers building custom Web Agents
- Upgraded version of crawlers/data collection

- Custom RPA replacement
Pros
- Most popular Web Agent framework in the open-source community
- Simple Python API
- Supports any LLM as the brain
- Active community with 50,000+ stars on GitHub

Pricing
Completely open source and free. Running cost = LLM API call fees + self-deployed hardware. Can be used with any OpenAI-compatible API.
Summary
Browser Use is the de facto standard for open-source Web Agents—reducing "LLM operating a browser" to just a few lines of Python. It is the top choice for developers building Web Agents; for productization needs, consider the commercial version of Skyvern.
