# rea vs n8n

rea and n8n share 5 technologies: MCP, @clack/prompts, yaml, Zod, and Ajv. Both are written in TypeScript.

- [morluto/rea](https://seerepo.com/r/morluto/rea): Reverse engineer anything with agents, from app behavior down to native binaries.
- [n8n-io/n8n](https://seerepo.com/r/n8n-io/n8n): Fair-code workflow automation platform with native AI capabilities. Combine visual building with custom code, self-host or cloud, 400+ integrations.

| Who writes it | 16.3% of its commits signed by AI. With Claude Code, Codex, Cursor, Factory, GitHub Copilot, and Devin | 14.4% of its commits signed by AI. With Claude Code, Cursor, GitHub Copilot, Codex, and CodeRabbit |
| Activity | Last push November 4, 2026, 5,979 commits, 428,191 stars | Last push November 4, 2026, 26,047 commits, 209,517 stars |
| Tests | 3,518 test files. 66.6% of its code files have a test that imports them | 10,704 test files. 53.7% 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.
