Evidence status
Ollama supports running models on your own hardware and also offers optional cloud plans. Local runtime cost is separate from hardware, electricity, model licenses, and any cloud usage; the official pricing page lists current cloud tiers.
Official sources checked 2026-08-26Open verification questions
- Each model has its own license and usage terms; Ollama does not make every model legally interchangeable.
- Hardware performance, context limits, and output quality vary by model and quantization.
Official docs state the local API is served at localhost:11434 by default and provide official Python and JavaScript libraries. Ollama's FAQ distinguishes local runs from cloud-hosted models and explains model storage locations.
Open WebUI is self-hosted software; its official license documentation describes the current licensing and branding requirements, including distinctions for larger deployments. Optional enterprise/support arrangements are separate.
Official sources checked 2026-08-26Open verification questions
- Backend provider retention and telemetry may differ from the Open WebUI application.
- Enterprise features, support, and licensing for larger deployments require direct confirmation.
Official documentation describes Docker, Python, and Kubernetes paths plus connections to Ollama, OpenAI, Anthropic, vLLM, RAG, tool calling, and multi-user capabilities. Read the current license page before rebranding or redistributing.
