Overview
Drag-and-drop UI to build LLM workflows
Pros
- ✓ Drag-and-drop LangChain/LlamaIndex workflow builder — no Python coding required
- ✓ 300+ built-in nodes covering LLMs, vector stores, document loaders, and tools
- ✓ Deployable as a standalone API — export workflows as REST endpoints
- ✓ Active development with frequent updates and new node additions
Cons
- ✗ Visual workflows become hard to maintain at scale — not ideal for production systems with complex branching logic
- ✗ Feature parity with LangChain's Python API lags slightly
- ✗ Self-hosted requires Node.js setup; Docker deployment is more reliable
- ✗ Complex custom logic still requires dropping into code nodes
