# playwright vs rea

playwright and rea share 4 technologies: MCP, yaml, Zod, and xterm. Both are written in TypeScript.

- [microsoft/playwright](https://seerepo.com/r/microsoft/playwright): Playwright is a framework for Web Testing and Automation. It allows testing Chromium, Firefox and WebKit with a single API. 
- [morluto/rea](https://seerepo.com/r/morluto/rea): Reverse engineer anything with agents, from app behavior down to native binaries.

## What they share and what sets them apart

- In common: MCP, yaml, Zod, xterm
- Only in playwright: React, DuckDB, Electron, Vite, xml2js, jpeg-js, pngjs, enquirer, zod-to-json-schema, codemirror
- Only in rea: @clack/prompts, cairosvg, @xmldom/xmldom, plist, parse5, saxes, Ajv, ajv-formats, har-schema, pino

| Who writes it | 0.5% of its commits signed by AI. With GitHub Copilot, Claude Code, and Cursor | 16.3% of its commits signed by AI. With Claude Code, Codex, Cursor, Factory, GitHub Copilot, and Devin |
| Activity | Last push November 4, 2026, 18,394 commits, 99,277 stars | Last push November 4, 2026, 5,979 commits, 428,191 stars |
| Tests | 844 test files. 10% of its code files have a test that imports them | 3,518 test files. 66.6% of its code files have a test that imports them |

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
