# webrain vs Browser Use

> Honest comparison of webrain and Browser Use — an MCP-native scraping server in Rust vs a Python AI browser-agent library that controls Playwright.

# webrain vs Browser Use

**Browser Use** is an open-source **Python library** for AI browser agents — an
agent loop drives a Playwright-controlled browser with a chosen LLM; a cloud
service and an MCP server also exist. **webrain** is an open-source **Rust MCP
server** that exposes browser/scrape capabilities to any LLM client.

| Dimension       | webrain                                      | Browser Use                          |
| --------------- | -------------------------------------------- | ------------------------------------ |
| Core            | Rust MCP server, single binary               | Python library (agent loop)          |
| LLM integration | Any MCP client (Claude, Cursor, Copilot…)    | Bring your own LLM key + agent loop  |
| Engines         | Chrome, Lightpanda, Obscura, no-browser HTTP | Playwright (Chromium/Firefox/WebKit) |
| Extraction      | Autoschema/schema/regex/table/JSON-LD/BM25   | DOM-centric, LLM extraction          |
| Crawling        | Spider, sitemap, batch                       | Library-level                        |
| Deployment      | Local, no cloud, no key required             | Cloud tier available                 |
| Video/PDF/watch | Built-in                                     | —                                    |

**Pick Browser Use** when you want an **agent framework in Python** with a
tight LLM loop and are comfortable owning the runtime.

**Pick webrain** when you want **MCP-native browser/scraping tools** any
client can drive — one binary, no Python runtime, local-first, with
extraction, crawling, auth, PDF, and video built in.
