LangChain is the most popular framework for building LLM applications with chains, agents, memory, and retrieval. LangSmith adds observability. Controversial for its abstraction complexity.

Open WebUI is a self-hosted ChatGPT-like interface for Ollama and other LLM providers. Multi-model support, RAG, web search, and document analysis.
Reviewer scorecard
“Over-abstracted and changes too fast. For anything beyond demos, calling APIs directly with a thin wrapper is more maintainable.”
“The best self-hosted chat interface for local LLMs. Multi-model, RAG, and plugin support in one package.”
“The framework that made simple API calls into 500-line abstractions. LangGraph is better but the damage is done.”
“Deploy with Docker, connect to Ollama, and you have a private ChatGPT. The feature set is remarkably complete.”
“Despite the criticism, LangChain's ecosystem (LangSmith, LangGraph, templates) is the most complete platform for LLM apps.”
“Self-hosted AI interfaces will be standard for privacy-conscious users and organizations. Open WebUI leads here.”
