# pi vs n8n

pi and n8n share 4 technologies: OpenAI, Anthropic, yaml, and highlight.js. 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
- [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.

## What they share and what sets them apart

- In common: OpenAI, Anthropic, yaml, highlight.js
- Only in pi: React, lowlight, marked, @aws-sdk/client-bedrock-runtime, @silvia-odwyer/photon-node, typebox, @xterm/headless
- Only in n8n: Postgres, Supabase, MCP, Vite, Redis, Express, Vue, vue-router, MongoDB, SQLite, lru-cache, Sentry, PostHog, MySQL, Kafka, ai, @ai-sdk/provider-utils, Zod, Ajv, opentelemetry, LangChain, pdf-parse, @joplin/turndown-plugin-gfm, @mozilla/readability, turndown, xss, validator, logform, winston, jose, jsonwebtoken, CodeMirror, @lezer/highlight, class-validator, linkedom, mammoth, @clack/prompts, @aws-sdk/credential-providers, epub2, Cheerio, html-to-text, sanitize-html, bcryptjs, otpauth, file-type, nodemailer, class-transformer, markdown-it, tiptap, vuedraggable, Chart.js, katex, rss-parser, pdfjs-dist

## Side by side

| | pi | n8n |
|---|---|---|
| Size | 677,258 lines written, 1,543 code files | 5,241,398 lines written, 14,224 code files |
| Who writes it | 0.3% of its commits signed by AI. With Claude Code, Gemini CLI, Cursor, and Amp | 14.4% of its commits signed by AI. With Claude Code, Cursor, GitHub Copilot, Codex, and CodeRabbit |
| Activity | Last push November 4, 2026, 7,130 commits, 119,972 stars | Last push November 4, 2026, 26,047 commits, 209,517 stars |
| Tests | 1,475 test files. 46.8% 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.
