# webrain vs Playwright

> Honest comparison of webrain and Playwright — a purpose-built MCP scraping/automation server vs Microsoft's browser automation and testing library.

# webrain vs Playwright

**Playwright** is Microsoft's open-source browser-automation **library and
testing framework** (Node, Python, .NET, Java) with a first-party MCP server
(`@playwright/mcp`). **webrain** is a purpose-built, open-source **MCP server**
for LLM-driven scraping and automation. Both drive Chromium over CDP.

| Dimension   | webrain                                         | Playwright                       |
| ----------- | ----------------------------------------------- | -------------------------------- |
| Form factor | Single Rust binary (MCP server + CLI)           | Library in Node/Python/.NET/Java |
| MCP         | Native — 15 tools, first class                  | Via `@playwright/mcp` server     |
| Engines     | Chrome, Lightpanda, Obscura + no-browser HTTP   | Chromium, Firefox, WebKit        |
| Extraction  | Autoschema/schema/regex/table/JSON-LD/BM25      | Manual selectors                 |
| Crawling    | Spider, sitemap, scan, batch                    | Library (manual)                 |
| Auth        | Encrypted vault + TOTP, cookie transfer         | Manual                           |
| Video/PDF   | `watch` (transcript+frames), PDF extract/render | —                                |
| Runtime     | No Node/Python runtime                          | Requires Node/Python             |

**Pick Playwright** when you're writing a browser **test suite** in your
existing language and want WebKit/Firefox coverage.

**Pick webrain** when an **LLM/agent** (Claude, Cursor, Copilot) must scrape,
navigate, extract, and authenticate as a service — no code, no runtime, MCP
out of the box.

Puppeteer sits alongside Playwright in the same category — Chrome-only and
lower-level — so the same "library vs MCP server" trade-off applies.
