Our take
Pick LangChain if engineers building agents in Python or JS who will read traces when something breaks. Pick Ollama if developers and privacy-sensitive teams who have RAM/VRAM and want Llama/Gemma/DeepSeek without a per-seat chat plan. Skip LangChain if no-code ops teams (Zapier / Make) or people who only want a visual canvas (Langflow / Dify). Skip Ollama if someone who wants a polished hosted chat with browsing
