Web UI for EvoScientist — a self-evolving AI scientist built on DeepAgents/LangGraph.

Package Exports

    This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@evoscientist/webui) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

    EvoScientist WebUI

    Web UI for EvoScientist — a self-evolving AI scientist built on DeepAgents/LangGraph.

    The browser connects directly to a running EvoScientist deployment and gives you a chat interface with streaming responses, tool calls, sub-agent activity, files, and tasks.

    Prerequisites

    • Node.js 20+

    • A running EvoScientist backend (the LangGraph deployment). From your EvoScientist install, start it with:

      EvoSci deploy        # serves the LangGraph API at http://127.0.0.1:6174

      Keep this running in its own terminal.

    Quick start (development)

    npm install
npm run dev

    Open http://localhost:4716. In the configuration dialog, enter your Deployment URL (default http://127.0.0.1:6174) and click Save. That's it — start chatting.

    You need two things running: the EvoScientist backend (EvoSci deploy, port 6174) and this UI (npm run dev, port 4716).

    Production build

    npm run build        # outputs the optimized app
npm start            # serves it on http://localhost:4716

    Configuration

    • Deployment URL — the EvoScientist LangGraph endpoint (default http://127.0.0.1:6174, the EvoSci deploy default port). Saved in your browser's local storage.
    • The UI always talks to the EvoScientist main agent; its sub-agents (writing-agent, data-analysis-agent) are internal and not user-selectable.
    • (Optional, advanced) Set NEXT_PUBLIC_LANGSMITH_API_KEY if you connect to a deployment that requires LangSmith authentication.

    Scripts
