# Archon vs paperclip

Archon and paperclip share 14 technologies: Postgres, Anthropic, Vite, React, Zod, @clack/prompts, yaml, pino, Ajv, Better Auth, Tailwind CSS, Lucide, react-markdown, and remark-gfm. Both are written in TypeScript.

- [coleam00/Archon](https://seerepo.com/r/coleam00/Archon): The first open-source harness builder for AI coding. Make AI coding deterministic and repeatable.
- [paperclipai/paperclip](https://seerepo.com/r/paperclipai/paperclip): The open-source app everyone uses to manage agents at work

## What they share and what sets them apart

- In common: Postgres, Anthropic, Vite, React, Zod, @clack/prompts, yaml, pino, Ajv, Better Auth, Tailwind CSS, Lucide, react-markdown, remark-gfm

| Size | 666,863 lines written, 1,890 code files | 3,133,031 lines written, 5,090 code files |
| Who writes it | 12.7% of its commits signed by AI. With Claude Code, GitHub Copilot, CodeRabbit, and Gemini CLI | 17% of its commits signed by AI. With Claude Code, Codex, Cursor, and GitHub Copilot |
| Activity | Last push November 4, 2026, 3,643 commits, 23,825 stars | Last push November 4, 2026, 5,942 commits, 111,002 stars |
| Tests | 1,069 test files. 42.7% of its code files have a test that imports them | 4,571 test files. 60.3% 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.
