Browser Use

Browser Use is an open-source Python library that lets AI agents control a real browser using LLMs instead of brittle CSS selectors or XPath scripts. Rather than pre-programming every interaction with selector code, a developer describes the task in natural language and the agent works out how to execute it against whatever website it encounters, including sites it has never seen before. The repository holds 120k GitHub stars and carries an MIT license, so the library itself is free to run on your own compute with your own LLM API keys. Because the agent reasons from the current visual and DOM state rather than hardcoded selectors, it adapts when a website layout changes, which makes it usable against legacy web applications and any site without a public API.

Browser Use, Inc. sells two commercial products on top of the library. Browser Use Agents take a task and return completed work through the V4 API, with models from OpenAI, Anthropic (Claude), Google (Gemini), xAI, DeepSeek, MiniMax and Z.ai selectable per run, plus BU 2.0, a model Browser Use built for web agents. Browser Infrastructure gives your own agents and automations managed cloud browsers through the SDK, REST or the Chrome DevTools Protocol, with stealth fingerprinting, free CAPTCHA solving, persistent profiles and residential proxies in 195 plus countries. Playwright, Puppeteer and Selenium scripts connect to those browsers over CDP.

The library integrates with any LLM via BYOK, including OpenAI, Anthropic, Google Gemini, Groq, OpenRouter, Azure, Bedrock, DeepSeek and local models through Ollama, and the docs carry examples for LangChain and for n8n, Make.com and Zapier orchestration. Browser Use ships a hosted MCP server with six tools that hands a task to an agent on a cloud browser, documented for Claude Code, Claude Desktop, Cursor, Devin Desktop and ChatGPT in developer mode, and a local stdio server, browser-harness-mcp, that exposes click, type, read and screenshot on a Chrome where the user is already signed in. It also acts as an MCP client: the library includes a client module, and Browser Use Terminal takes an MCP config so the agent can call tools on external MCP servers. Named gaps: the cloud has no no-code builder for non-developers, content behind OAuth walls needs a saved browser profile or a human hand-off for the login step, and internal SaaS tools need custom tool definitions.

Pricing is public, in US dollars, and has no subscription. Every account starts free with a one-time $1 credit for eligible Google, GitHub or Microsoft signups, ten concurrent sessions and access to the cost-efficient models only. Paid usage is bought as credits, from $5 to $100,000 per top-up, and the credits never expire. Cloud browser time is $0.02 per browser-hour metered by the minute with a one-minute minimum, managed residential proxy traffic is $5 per GB, and direct or bring-your-own-proxy traffic is $0.20 per GB. Browser Use Agents bill the model cost plus 20 percent, so $1 of model usage costs $1.20 on top of browser time and traffic. Concurrency rises with lifetime spend, from ten sessions at $0 to 1,000 at $25,000, and Enterprise adds a negotiated annual credit pool, SLAs, data-retention terms and dedicated support. The Dev, Business and Scaleup subscriptions that were sold until at least July 2026 are no longer offered to new accounts, and existing subscribers keep their plan.

What the free account does not buy is specific. The $1 credit does not renew, all models unlock only after a first top-up, and auto-recharge needs a card on file. The privacy policy, last updated July 15, 2026, states that Browser Use uses Inputs to train its AI models, and the only opt-out it describes covers marketing email. The open-source library runs on self-managed infrastructure, and Enterprise plans offer a custom data policy with zero data retention, HIPAA support and EU data residency on request. Browser Use is SOC 2 Type II compliant, audited by Accorp Partners over a July 17 to October 17, 2025 observation window, with the report available on request to support. Browser Use offers a signed DPA covering GDPR, UK GDPR and the Swiss FADP. No ISO 27001 certification is published.

Current state Q4 2026: Browser Use Agents V4 is the current API for new integrations, with API V3 and V2 still supported. The vendor publishes its own benchmarks, including 82 percent on a 106-task internal set at $0.17 per solved task, 98 percent across 300 Online-Mind2Web tasks, and 81 percent on a 71-site stealth benchmark, all measured by Browser Use itself. Browser Use Box, a 24/7 remote VM with Claude Code and Browser Harness pre-installed, launched in April 2026. Hermes Agent lists Browser Use as its default browser tool. Published case studies name Hermes Agent, Sauna, Parallel AI, Vesta and Composio, and the G2 profile now carries its first reviews, while the independent evidence rests mainly on the GitHub repository.
