wtf is deep-agents-ui?

Deep Agents UI is a visual interface for chatting with and monitoring AI agents built on the Deep Agents framework. Instead of interacting with your agent purely through code or a terminal, you get a clean chat window where you can send tasks, watch the agent work, and inspect the files it creates along the way. The tool connects to a running agent deployment, you provide a URL and an agent identifier, and the interface handles the rest. As the agent works through your request, the UI shows you its progress and surfaces the files it generates, which you can click on and view directly. There is also a Debug Mode that lets you step through the agent's actions one at a time and re-run individual steps, which is useful when you are trying to understand why an agent made a certain decision or when something goes wrong and you need to isolate where it happened. The primary audience is developers and technical founders who are already building agents with LangChain's Deep Agents framework and want a polished way to test and demo them. For example, if you have built a research agent that searches the web and writes reports, you can point this UI at it and immediately have a shareable interface where stakeholders can try it out. The debug capabilities also make it practical for anyone iterating on an agent's behavior who needs to see step-by-step what is happening under the hood. The project is built in TypeScript and runs locally with a few standard commands. It does not include agents itself, you need to have a Deep Agents deployment running separately, then connect to it. The README is straightforward about this being a companion UI rather than a standalone product, which is an important distinction for anyone expecting an out-of-the-box agent experience.
