# a2ui vs paperclip

a2ui and paperclip share 9 technologies: Google, MCP, React, OpenAI, jsonschema, Zod, Ajv, yaml, and dompurify. Both are written in TypeScript.

- [a2ui-project/a2ui](https://seerepo.com/r/a2ui-project/a2ui): Open-source generative UI framework: agents stream layout data, and apps render it with native components in React, Angular, Lit, Flutter, SwiftUI and Jetpack Compose.
- [paperclipai/paperclip](https://seerepo.com/r/paperclipai/paperclip): The open-source app everyone uses to manage agents at work
