SlotFlow

What it does

SlotFlow is a comprehensive AI agent workspace that combines FastAPI backend with Next.js frontend to create extensible, local-first autonomous agents. It leverages LangGraph for orchestration, supports multiple LLM providers (DeepSeek, OpenAI, Anthropic), and integrates MCP tools for enhanced capabilities. The platform enables reasoning streaming, artifact management, long-term memory persistence, and hierarchical sub-agent execution.

How to set up

Clone the repository from GitHub. Install Python dependencies for the FastAPI backend and Node.js dependencies for the Next.js frontend. Configure your LLM provider credentials (DeepSeek, OpenAI, or Anthropic API keys). Set up local database for memory persistence. Run the FastAPI server and Next.js development server. Access the workspace through the web interface.
