Question 1

How is Open WebUI on Opsily a secure ChatGPT alternative?

Accepted Answer

ChatGPT is a SaaS tool owned by OpenAI. Your prompts go to OpenAI's servers. Opsily is a hosting provider that runs Open WebUI, an open-source interface, on your own private instance in Frankfurt, Germany. Your data never leaves your infrastructure. You control the API keys, the data access, the backups, and the compliance audit trail. ChatGPT is convenient but not private. Open WebUI on Opsily is both.

Question 2

Is my data GDPR compliant on Opsily?

Accepted Answer

Yes. All servers run in Frankfurt, Germany (EU data center). Data processing complies with GDPR Article 32 (confidentiality, integrity, resilience). We do not process or access customer data without explicit consent. Daily encrypted backups are retained in the same region. You own the data controller relationship; we are the processor. For regulated industries (healthcare, finance, law), we provide a Data Processing Agreement (DPA) signed within 48 hours of request.

Question 3

Can I bring my own OpenAI API key?

Accepted Answer

Yes. You paste your API key into Open WebUI, and the interface uses your key to call OpenAI's API. Your prompts still go to OpenAI (because you are using their model), but the UI, the conversation history, the team access logs, and the backups all stay in your Opsily instance on German servers. This is a hybrid approach: private interface + your chosen backend. For full privacy, use local Ollama models instead.

Question 4

What if I want to use local AI models like Ollama instead of OpenAI?

Accepted Answer

Open WebUI supports Ollama, Mistral, Llama 2, and other open-source models. Deploy Ollama as a separate app on Opsily (or on your own hardware), and Open WebUI connects to it. All inference happens on your instance. No external API calls. No data leaves your control. This is the most private option, though accuracy may be lower than commercial models like GPT-4 depending on the local model you choose.

Question 5

How long does migration from ChatGPT Enterprise take?

Accepted Answer

Setup of Open WebUI on Opsily takes 3 minutes. Migrating your team takes 10 minutes: invite users by email, assign roles, confirm they can log in. There is no data migration because ChatGPT does not export your conversation history. You start fresh in Open WebUI. If you want to keep old conversations, export them manually from ChatGPT before switching. Your API spend moves to your own keys (if using OpenAI) or goes to zero (if using local models).

Question 6

What is RAG and how does it work with Open WebUI?

Accepted Answer

RAG (Retrieval-Augmented Generation) means the AI reads documents you upload: PDFs, contracts, customer specs, before answering your question. Open WebUI on Opsily includes 15+ search backends (web, Bing, Google Docs, Notion, Wikipedia) and lets you upload files locally. The file never goes to an external API. It stays in your instance and is embedded and searched by the local model or your chosen API. This is how you get custom ChatGPT trained on your own proprietary data without data leakage.

Question 7

Do you charge per conversation or per user?

Accepted Answer

No. Opsily charges a flat monthly rate per server: Small EUR20, Medium EUR40, Large EUR70, Unlimited EUR100. All plans include unlimited users, unlimited conversations, unlimited API calls (to your own keys or models). No per-seat tax. No overage charges. The price stays the same if you add 5 team members or 500. This is why Opsily is so much cheaper than ChatGPT Enterprise.

Question 8

Can I customize the login screen and branding?

Accepted Answer

Yes. Open WebUI lets you upload your logo, change colors, customize the login page, and set a custom domain. For example, chat.mycompany.com instead of a generic Opsily subdomain. This is included in all plans. Full white-label customization (custom domain, custom styling) is available on the Large and Unlimited plans.

Question 9

What happens to my data if I cancel my Opsily subscription?

Accepted Answer

You have 30 days to export your data after cancellation. All conversations, files, and settings can be downloaded as JSON. After 30 days, the instance is deleted and backups are purged (no exceptions for GDPR compliance reasons). If you need longer retention, contact support before canceling to arrange data archival.

Question 10

Is Open WebUI production-ready and actively maintained?

Accepted Answer

Yes. Open WebUI has 61.2K GitHub stars and is actively maintained with regular updates. Opsily keeps the hosted version current. For your compliance and security audits: the code is open-source, so you can review it, run security scans, and verify there are no backdoors. We provide weekly automatic updates with downtime notifications (usually less than 1 minute). Critical security patches are deployed within 24 hours.
