# AutoGPT vs Stirling-PDF

AutoGPT and Stirling-PDF share 5 technologies: React, FastAPI, Postgres, Stripe, and PostHog. AutoGPT is written in Python and Stirling-PDF in TypeScript.

- [Significant-Gravitas/AutoGPT](https://seerepo.com/r/Significant-Gravitas/AutoGPT): AutoGPT is the vision of accessible AI for everyone, to use and to build on. Our mission is to provide the tools, so that you can focus on what matters.
- [Stirling-Tools/Stirling-PDF](https://seerepo.com/r/Stirling-Tools/Stirling-PDF): #1 PDF Application on GitHub that lets you edit PDFs on any device anywhere

## What they share and what sets them apart

- In common: React, FastAPI, Postgres, Stripe, PostHog
- Only in AutoGPT: Next.js, Redis, Sentry, OpenAI, Anthropic
- Only in Stirling-PDF: Vite, Spring, Supabase, AWS S3

## Side by side

| | AutoGPT | Stirling-PDF |
|---|---|---|
| Size | 1,629,762 lines written, 4,321 code files | 1,143,405 lines written, 4,342 code files |
| Who writes it | 15.7% of its commits signed by AI. With Claude Code, GitHub Copilot, Cursor, CodeRabbit, Mistral Vibe, Factory, Codex, Devin, and Gemini CLI | 2.1% of its commits signed by AI. With GitHub Copilot, Claude Code, and Codex |
| Activity | Last push October 28, 2026, 9,375 commits, 187,791 stars | Last push October 27, 2026, 5,679 commits, 95,111 stars |
| Tests | 2,792 test files. 51.8% of its code files have a test that imports them | 2,064 test files. 48.8% 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.
