The best ChatGPT alternative for private teams
Stop paying $25 per seat for tools that train on your data. Host Open WebUI on Opsily for a private, enterprise-grade AI interface that you own completely. Connect any model, keep your data in Germany, and scale without the SaaS tax.
The Best ChatGPT Alternative for Cost Control
SaaS AI tools are convenient until you see the bill or the privacy policy. Open WebUI provides a superior interface with none of the lock-in.
Eliminate the per-user tax
ChatGPT Team costs $300 monthly for just 10 users. Opsily offers flat-fee hosting. Add your whole company to one instance without increasing your bill by a single cent.
True privacy by default
Your prompts never train public models. Hosted on private servers in Frankfurt, your data stays within your control. This is the essential standard for legal, medical, and fintech teams.
Model independence
Don't get locked into one provider. Open WebUI connects to Ollama, OpenAI, or Anthropic. Switch backends behind the scenes while your team keeps the same familiar interface.
Built for teams who need reliability

Why Open WebUI is the best ChatGPT alternative for 2026
Most people look for an alternative because of the price. ChatGPT Plus costs $20 for an individual, but for a team of 50, you are looking at $1,500 every single month. That is a massive recurring cost for a wrapper UI.
Break the model lock-in
When you use ChatGPT, you are tied to OpenAI. When you use Claude, you are tied to Anthropic. Open WebUI changes the power dynamic. It is a unified frontend that connects to any backend. Use Llama 3 for private internal data and GPT-4o for creative marketing tasks: all in the same chat window.
Built-in RAG (Retrieval Augmented Generation)
Open WebUI includes a powerful document management system. You can upload PDFs, text files, or even scrape website URLs by typing a simple '#' in the chat. The AI then answers specifically based on your documents. In the official apps, this is often clunky or restricted. In Open WebUI, it is a core feature.
Security that satisfies the CISO
For companies in the EU, the 'Safe Harbor' or 'Privacy Shield' frameworks are often not enough. Data residency matters. By hosting Open WebUI on Opsily's Frankfurt-based infrastructure, you ensure that PII (Personally Identifiable Information) never leaves the jurisdiction. It is the only way to deploy AI that actually meets strict compliance checks.
