PopUI - Collaborative UX for Claude Desktop
Overview
PopUI is a companion desktop app for macOS that gives Claude Desktop new tools.
Leveraging Claude's ability to create user interfaces, PopUI creates a bi-directional bridge to a visual context.
- Claude creates and automatically displays a user interface (similar to artifacts)
- Claude can read changes done in the UI and use the UI as a visual context
- Claude can also push changes to the UI, visually updating it for the user
- The UI can send events and text back to chat, obviating the need for keyboard input in the loop
Collaborative UX
How is this different from Artifacts?
PopUI closes the interaction loop. While Claude Artifacts can generate interactive UI elements, any events or changes that happen in them are trapped outside of the chat conversation. With PopUI, Claude has tools to interrogate and manipulate the external state, allowing Claude to build further conversation on top of that shared context.
Realtime visual context
PopUI also gives the Claude and the user the ability to receive and manipulate visual context.
Some examples:
- Instantly build control panels for tweaking and refining values in the chat
- Talk to Claude about colors with a color picker with swatches.
- Talk to Claude about a physical layout
- Play turn-based games with Claude on a shared gameboard
- Give Claude a sense of time with a real-time wall clock
- Give Claude a literal face to express its emotions during the chat
Installation
Just download the latest release and launch the app.
Automatic SSE Proxy to Claude Desktop
PopUI provides all its dependencies to function, even the MCP gateway for Claude! The first time you launch PopUI, you'll be asked to install into Claude Desktop. After this, PopUI will be launched by Claude Desktop and automatically connected as an MCP server.
You can access all the created user interfaces from the settings window or from the menubar icon.

This server cannot be installed
local-only server
The server can only run on the client's local machine because it depends on local resources.
A companion desktop app enabling bi-directional interaction between Claude Desktop and visual UI elements, allowing Claude to display, read from, and write to interactive interfaces while processing user events and feedback.
