"Across the most-reviewed tools, developers are choosing between broad workflow orchestration, local inference, and production oversight. Langchain leads for multi-step agents, RAG, integrations, and debugging; Ollama stands out for privacy-first local model serving and offline prototyping; while platforms like Latitude emphasize tracing, evaluation, and reliability as teams harden LLM apps for production."
