Comparison
Open WebUI alternative: onAI with support
Open WebUI is a self-hosted interface for AI models. Choose onAI for servers in Europe and direct support in German and English, from €17 per user/month including €5 of model use.
Choose the deployment and who operates it
With onAI, your contracting party is Swiss and the application runs on servers in Europe. If your deployment needs a different arrangement, you can request a dedicated server or installation on your own servers.
Open WebUI gives your team control over where the application, files and indexes run. You also take responsibility for the deployment. External model, search or extraction services can receive data separately, so choosing your own server location does not settle every data-location question.

Approve model access for each group
In onAI, administrators decide which models each group may use. We enable new models shortly after release, and your own provider contracts and API keys are possible on request.
Open WebUI lets users select connected local or cloud models and compare several in a chat. Your administrators configure the endpoints and credentials, which determine the available selection. That suits teams that want to assemble and operate their own model connections.

Compare image results in one studio
Compare up to three image models side by side in onAI Image Studio. It includes models from OpenAI, Google, Black Forest Labs and xAI, styles with automatic prompt improvement, and editing with up to ten reference images. You see the estimated cost before generating.
Open WebUI also generates and edits images in chat, including edits to uploaded images and multi-image compositions. An administrator first configures an image engine and the relevant permissions. OpenAI, Gemini, ComfyUI and AUTOMATIC1111 are documented routes. Your chosen service determines the available models, costs and output terms.

Budget for the service and the operation
onAI starts at €17 per user and month with €5 of model use included; larger teams pay less. A fixed company price is also available. Onboarding and training are included in that fixed price.
Open WebUI standard software has no seat fee when you retain its original branding. Hosting, model inference and operations remain separate costs; Enterprise rights and services have a separate offer. If you already have infrastructure and operating capacity, the software licence can be attractive. For a company rollout, include the people running it in your budget.

- From €17 per user/month Includes €5 of model use; lower for larger teams, or a fixed price

Set permissions and spending limits
onAI administrators allow models and functions such as images, translation and web search per group. They can set cost limits per organisation and person, then inspect usage by model, feature and person. This gives you a concrete way to define who may use a tool and how much each person may spend.
Open WebUI has roles and additive group permissions for functions and shared resources. Its analytics reports activity and provider-reported tokens by user, model and group. Enforced monetary budgets were not established in the documentation check. If these limits matter to your rollout, ask for a demonstration of the intended configuration.

Case Study
Secure AI for 6,800 employees: how Manor established a privacy‑compliant alternative to ChatGPT across the company with onAI.
Thanks to the latest AI capabilities in onAI, our employees are more productive and use them securely and compliantly — at an affordable fixed price.
Where onAI fits better
Choose onAI if you want to give employees a browser workspace with a direct contact for onboarding and daily use.
Translation for everyday documents
The built-in DeepL translator handles documents with their layout, glossaries and formal or informal address. You can also adjust style and tone.
Help from the team
You reach our team directly in German or English. We agree service levels and response times in the contract, and build custom agents and workflows as a service.
Where Open WebUI fits better
Open WebUI fits an IT team that wants to run the application and connect its own model infrastructure.
Local inference under your operation
Ollama, llama.cpp and vLLM are documented routes for local chat. Local retrieval is also possible with local embedding models and extraction services.
SCIM in your deployment
Open WebUI documents SCIM for creating and deactivating users and managing groups. Enable SCIM and configure its bearer token to use it. Login-time identity groups are another route. Check retained content and ownership when you test user removal.
What onAI could do better
No SCIM provisioning
onAI creates users at first SSO sign-in and takes groups from the directory; it has no SCIM.
The application source is not public
onAI is proprietary software. Its application source is not public; included open-source components keep their own licences.

Book a demoQuestions you might have
- Is Open WebUI free for a company?
- Standard use has no software seat fee with the original branding retained. Your infrastructure, operations and model services still need a budget; Enterprise rights and services are separate. onAI instead has a per-user offer with included model use or a fixed company price.
- Does self-hosting keep every prompt on our servers?
- The application location and the inference endpoint are separate decisions in Open WebUI. Connected external services can receive prompts or documents; offline operation requires local dependencies. onAI also offers installation on your own servers and local models on request with that deployment.
- Can we use our own provider contracts with onAI?
- Your own provider contracts and API keys are possible on request, for example for Azure or OpenRouter. Open WebUI also supports customer-held credentials and configured endpoints.
- How can our team evaluate onAI?
- We start with a personal demo, followed by trial access for your team. Use it to assess your documents and the tools employees need. If you choose the fixed price, onboarding and training are included.
