ChatGPT Alternative for Business: Keep Your Data Private
ChatGPT sends your prompts to OpenAI's servers for training and improvement. Open WebUI does the opposite: everything stays in your control. Multi-user access. No vendor lock-in. GDPR compliant. Opsily hosts it, you own it.
ChatGPT Alternative for Business: Why Open WebUI
Three core reasons teams switch from ChatGPT.
Your Data Stays Private
ChatGPT analyzes and trains on your prompts. Open WebUI runs on your infrastructure, period. Prompts never leave your servers. No surprise data processing agreements. No compliance headaches. Your data is yours.
Built for Team Collaboration
ChatGPT Plus is a single-user tool. Open WebUI includes multi-user access, role-based permissions, shared conversation histories, and audit trails. Every prompt is logged. Every user is tracked. Accountability built in.
Complete Infrastructure Control
Hosted on your servers or in your EU region. No vendor lock-in to OpenAI or any other provider. Swap LLMs without rebuilding. Opsily handles the ops, you keep the keys. Your data, your rules, your choice.
Built for teams who need reliability
How It Works in 4 Steps
From zero to secure AI chat for your team in one afternoon.
Choose Your App
Select an app to get started.
Deploy Open WebUI
Opsily provisions your instance in your chosen region. German, US, or EU infrastructure. All encrypted by default. You're ready in minutes, not days.
Choose Your LLMs
Connect Ollama for local models, or plug in your own API keys. ChatGPT, Claude, Llama, Mistral, or any LLM. No lock-in. Change providers whenever you want.
Add Your Team
Invite team members with granular access controls. Admins, moderators, users. Each role has different permissions. Everyone sees the audit log. Full transparency.
Go Secure
Everything is encrypted in transit and at rest. Daily automated backups. Compliance reporting ready. Your team chats securely from day one.
ChatGPT vs. Open WebUI
Pricing as of June 2026. ChatGPT Enterprise pricing subject to change.
ChatGPT's Data Problem
OpenAI's privacy policy is clear: they use your prompts to improve their models. For solo founders? Fine. For teams handling customer data, financial information, or legal documents? It's a compliance nightmare.
A single prompt containing client names, contract terms, or deal figures gets analyzed by OpenAI's infrastructure. Your data processor agreement doesn't cover it. Your legal team says no.
Open WebUI Solves It
Everything runs on your servers. No data leaves your infrastructure (unless you explicitly connect an external API, and even then you control it). Your CISO sleeps at night. Your legal team signs off.
The second layer: team features. ChatGPT is built for individuals. Open WebUI is built for teams. Shared conversations. Role-based access. Audit logs that show who said what when. You get accountability.
The third layer: cost. At 50 people, ChatGPT Enterprise becomes expensive. Fixed infrastructure cost on Opsily stays flat. No per-user, per-message, or per-token pricing games.
All Plans Include
No gatekeeping by tier. Every plan gives your team the full feature set.
Simple, Transparent Pricing
No per-user fees. No surprise increases. One flat price. Choose how many apps you run. For Open WebUI: that's just one instance, so all plans work the same—the tier determines your support level and additional apps if you need them.
