# pi vs paperclip

pi and paperclip share 4 technologies: React, OpenAI, Anthropic, and yaml. Both are written in TypeScript.

- [earendil-works/pi](https://seerepo.com/r/earendil-works/pi): AI agent toolkit: unified LLM API, agent loop, TUI, coding agent CLI
- [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: React, OpenAI, Anthropic, yaml
- Only in pi: lowlight, marked, @aws-sdk/client-bedrock-runtime, @silvia-odwyer/photon-node, highlight.js, typebox, @xterm/headless
- Only in paperclip: Express, Postgres, MCP, Google, AWS S3, Tokio, Vite, Sentry, Svix, react-router-dom, Zod, @opentelemetry/resources, @clack/prompts, Drizzle, hmac, react-markdown, remark-gfm, jsonschema, Ajv, @daytonaio/sdk, three, Better Auth, ai, @ai-sdk/amazon-bedrock, sharp, dompurify, ajv-formats, opentelemetry, pino, Tailwind CSS, class-variance-authority, tailwind-merge, Radix UI, motion, dnd-kit, lexical, @lezer/highlight, Base UI, cmdk, CodeMirror, Mermaid, react-resizable-panels, xterm, Lucide, @assistant-ui/react

## Side by side

| | pi | paperclip |
|---|---|---|
| Size | 677,258 lines written, 1,543 code files | 3,133,031 lines written, 5,090 code files |
| Who writes it | 0.3% of its commits signed by AI. With Claude Code, Gemini CLI, Cursor, and Amp | 17% of its commits signed by AI. With Claude Code, Codex, Cursor, and GitHub Copilot |
| Activity | Last push November 4, 2026, 7,130 commits, 119,972 stars | Last push November 4, 2026, 5,942 commits, 111,002 stars |
| Tests | 1,475 test files. 46.8% 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.
