Overview
Browser Use is an open-source browser automation agent framework, with the core positioning of "enabling LLMs to navigate web pages and execute tasks." It quickly surpassed 100,000 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 such as "click/input/scroll/navigate" and execute them. Developers can use just a few lines of Python code to let Claude/GPT/Gemini autonomously operate the browser, making it an open-source alternative to commercial products like Skyvern.
**📌 2026 Update**: Browser Use's GitHub Stars have grown from 50,000 to **over 107,000**, 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). Developers can use Browser Use for complete browser automation agents and Chrome DevTools MCP for debugging and inspection. Together, they form the standard combination for AI Agent + browser in 2026.
Key Features

- Structured DOM to Model: Extracts web page elements into structured data, reducing LLM comprehension difficulty
- 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
- Stealth Browsers: Anti-detection browser infrastructure, simulates humans through fingerprints (canvas, webgl, audio), supports proxies in 195+ countries, $0.02/hour
- Fully Hosted Web Agents: Cloud-hosted browser automation, billed per step, $0.006/step
- Custom Models: Custom LLMs designed for browser automation, supporting multiple models (e.g., Gemini Flash, Sonnet 4.5), LLM prices starting from $0.36/M
Use Cases
- Developers building custom Web Agents
- Upgraded web scraping/data collection
- QA automated testing

- Custom RPA replacement
Pros
- Most popular Web Agent framework in the open-source community
- Concise Python API
- Supports any LLM as the brain
- Active community with 100,000+ GitHub stars
- Can be customized and extended
- Received $17 million in funding, continuously iterating
Pricing
The open-source version is completely free; running costs = LLM API call fees + self-deployed hardware. Commercial cloud services offer: Stealth Browsers $0.02/hour, Fully Hosted Web Agents $0.006/step, Custom Models billed per task (LLM prices starting from $0.36/M, e.g., 53 tasks/$1 for Gemini Flash, 19 tasks/$1 for Sonnet 4.5). Can be used with any OpenAI-compatible API.
Summary
Browser Use is the de facto standard for open-source Web Agents—reducing "LLM browser operation" to just a few lines of Python. It is the first choice for developers building Web Agents; for productization needs, consider the Skyvern commercial version.
