# composio vs ai-engineering-from-scratch

composio and ai-engineering-from-scratch share 7 technologies: OpenAI, Hono, Zod, google-adk, LangChain, @hono/node-server, and @mastra/core. composio is written in TypeScript and ai-engineering-from-scratch in Python.

- [ComposioHQ/composio](https://seerepo.com/r/ComposioHQ/composio): Composio powers 1000+ toolkits, tool search, context management, authentication, and a sandboxed workbench to help you build AI agents that turn intent into action.
- [rohitg00/ai-engineering-from-scratch](https://seerepo.com/r/rohitg00/ai-engineering-from-scratch): Learn AI Engineering! Learn it. Build it. Ship it for others.

## What they share and what sets them apart

- 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.
