Overview
Open WebUI is an extensible, self-hosted AI interface in the platforms category: users run chat, RAG over documents, multi-user workspaces and function calling against local runtimes such as Ollama or any OpenAI-compatible API. It is an open-source project published under the name Open WebUI, installed and operated by the user as a self-hosted web app or through its API rather than offered as a hosted service. It is free to self-host and licensed as BSD-3-Clause with an added branding clause. No material change was found in this review. Its limitation is commercial transparency: the project publishes no pricing page, because openwebui.com/pricing returns 404, so no plan price is recorded.
