amosjyng/langchain-visualizer

Provides real-time execution tracing adapted from Ought's ICE interface, displaying full prompt text with color-coded template variables versus hardcoded content, execution flow with stack timing, and per-call LLM costs. Integrates directly into LangChain workflows via a single import statement and supports both async scripts and Jupyter notebooks. Also enables visualization of document embedding and chunking operations alongside agent interactions.
