Reviewer scorecard
“If you're in the .NET ecosystem, this is the best AI integration SDK. Plugin architecture is clean and extensible.”
“The best self-hosted chat interface for local LLMs. Multi-model, RAG, and plugin support in one package.”
“Microsoft vendor lock-in disguised as open source. Everything points you toward Azure. Use provider-agnostic alternatives.”
“Deploy with Docker, connect to Ollama, and you have a private ChatGPT. The feature set is remarkably complete.”
“Enterprise AI adoption will go through existing stacks. Semantic Kernel meets .NET developers where they are.”
“Self-hosted AI interfaces will be standard for privacy-conscious users and organizations. Open WebUI leads here.”
