LM Studio vs Ollama Client
LM Studio and Ollama Client are complementary, not competitors. LM Studio is a desktop application that discovers, downloads, and serves local models with a built-in chat window. Ollama Client is a browser extension that connects to a running model server — including LM Studio’s — and adds browser-native grounding like page context, file RAG, web search, and tool calling. Many users run both.
