Open WebUI

Best for

Best for teams that want one self-hosted chat front end over local and cloud models, with the data staying on their own infrastructure.

Full Comparison

Criterion Ollama Open WebUI
Starting price Free for local models; Pro from $20 / month Local models cost nothing. Pro is $20 per month or $200 per year and includes $60 of cloud usage credits a month with three concurrent requests; Max is $100 per month with $300 of credits and ten concurrent requests; Team is $500 per month with $1,000 of shared credits and unlimited users; Enterprise is quoted. Extra credits can be bought on every paid plan. Free, self-hosted; enterprise licence quoted The community edition is free to deploy as-is with the Open WebUI branding kept. An enterprise licence is required to white-label or rebrand it or to use enterprise-only features, and is quoted against the number of seats.
Free trial Free plan with local models, starter cloud credits and one concurrent request Free community edition, self-hosted
Output Not stated A self-hosted chat interface over local and cloud models
API Yes, one REST API for local and cloud models, with Python and JavaScript libraries and a separate web search API Yes, a REST API with an OpenAI-compatible chat completions endpoint and Anthropic-compatible messages endpoints
Hosting Runs locally on macOS, Windows and Linux; cloud models run on Ollama's servers in the United States, Europe and Singapore Self-hosted by pip, uv, Docker or Kubernetes; runs fully offline and in air-gapped environments
Ecosystem Desktop app and command line for macOS, Windows and Linux, with integrations for VS Code Chat, Claude Code, OpenCode and n8n Self-hosted web interface with a plugin and tool marketplace, plus companion projects Open Terminal for code execution, oikb for knowledge-base sync and mcpo for MCP-to-OpenAPI proxying
Live web search and sources Yes, through a separate web search API returning a title, URL and content snippet per result; it needs a free account and an API key, and is also reachable over MCP Yes, through dozens of providers including SearXNG, Google PSE, Brave Search, Kagi, Mojeek, Tavily, Perplexity and Firecrawl, with results injected into the conversation
Files and long documents Yes, the desktop app takes files by drag and drop so a model can reason over text or PDFs, and code files can be passed in for understanding; for large documents the context length is raised in the settings, which the vendor notes costs more memory Yes, local retrieval backed by nine vector databases, with several content-extraction engines and hybrid BM25 plus vector search with reranking
Images, voice and video Images for vision-capable models, passed as a file path, URL or base64 through the API and the libraries Image generation through DALL-E, Gemini, ComfyUI and AUTOMATIC1111, plus hands-free voice and video calls with a choice of speech-to-text and text-to-speech engines
Coding help Coding models in the library, plus integrations with terminal coding agents such as Claude Code and OpenCode and with VS Code Chat Open Terminal adds sandboxed files, a shell, code execution, previews and artifacts inside the chat
Model choice Yes, and it is the point: any model from the library or an imported custom one, run locally or offloaded to the cloud through the same call Yes, and it is the point: Ollama for local models and any OpenAI-compatible API, including LM Studio, GroqCloud, Mistral, OpenRouter and vLLM, mixed locally or in the cloud

The trade-offs

Strengths and Limitations

Ollama

Strengths

  • Models run on your own machine, so on the free plan nothing is sent anywhere
  • The same API covers local and cloud models, so a model can be swapped without changing code
  • Chat, coding, vision, embedding and reasoning models in one library, plus imported custom models
  • Cloud use can be switched off entirely for a fully local setup

Limitations

  • Large models need capable local hardware; otherwise they run in the cloud on a paid plan
  • Cloud models and the web search API need an account and usage credits
  • Paid plans are metered in usage credits rather than seats, so the monthly cost varies with how hard it is used

Open WebUI

Strengths

  • Runs entirely on your own infrastructure, including fully offline and air-gapped
  • One interface over local Ollama models and any OpenAI-compatible API
  • Granular role-based access control and user groups for teams
  • Free to deploy as-is, with no seat cost
  • Its own OpenAI-compatible API, so other applications can call through it

Limitations

  • No hosted service: you run, secure and upgrade the infrastructure yourself
  • White-labelling or rebranding requires a quoted enterprise licence, and the community licence requires keeping the Open WebUI branding
  • Enterprise pricing is not published
