RUNTIME_OVERVIEW
Open WebUI is a self-hosted-style web interface that can connect to local providers such as Ollama and to cloud-compatible providers.
Install Ollama first, verify it works, then add Open WebUI. Confirm the provider is local before uploading private files.
Open WebUI can be local or cloud-connected depending on provider settings. A browser UI does not prove local inference.
BEST_FOR
·browser UI over Ollama;
·users who want a ChatGPT-like local workspace;
·home-lab or self-hosted-style workflows;
·document and knowledge workflows after setup;
·people comfortable with Docker/server concepts.
NOT_GOOD_FOR
·users who do not want to manage local server settings;
·users confused by Docker networking;
·sensitive documents before provider and embedding settings are reviewed;
·claims that the full workflow is local without verification.

CAVEATS
·Open WebUI is a UI/provider layer, not a local model runtime by itself.
·Provider, embedding, vector database, file extraction, CORS, telemetry, and deployment settings can change data flow.
·Local AI Guide has not independently deployed, audited, or benchmarked Open WebUI.
