Why This Track Matters

Flowise makes LLM orchestration visual and accessible — a drag-and-drop canvas for building production pipelines without boilerplate, with auto-generated APIs for every workflow you create.

This track focuses on:

  • building LLM workflows visually with Flowise's node canvas
  • developing custom nodes to extend Flowise with new integrations
  • connecting LLM providers, vector stores, and tools in production pipelines
  • deploying and monitoring Flowise workflows with Docker

What Is Flowise?

Flowise is an open-source visual workflow builder for LLM applications. It provides a drag-and-drop canvas for connecting AI models, data sources, and tools into production-ready pipelines — without writing boilerplate code.
