# composio vs CopilotKit

composio and CopilotKit share 14 technologies: OpenAI, Hono, Zod, CrewAI, google-adk, LangGraph, LangChain, Pydantic, jsonschema, zod-to-json-schema, @hono/node-server, @cfworker/json-schema, @mastra/core, and ai. Both are written in TypeScript.

- [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.
- [CopilotKit/CopilotKit](https://seerepo.com/r/CopilotKit/CopilotKit): The Frontend Stack for Agents & Generative UI. React, Angular, Mobile, Slack, and more.  Makers of the AG-UI Protocol

- 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.
