Run ChatGPT Locally for Free. Keep Your Data Private.
Stop paying $20/month for ChatGPT. Deploy a local ChatGPT alternative with Open WebUI and Ollama. Full control. No API costs. No vendor lock-in.
Why Choose Local ChatGPT with Opsily?
Running ChatGPT locally is not just cheaper. It's smarter.
Save $20/Month (Forever)
ChatGPT Plus costs $20/month. Open WebUI costs nothing. Host it yourself on Opsily and pay a flat fee for server space instead of per-seat subscriptions. No more $20 x 10 team members = $200/month bills. One server. One price. Unlimited users.
Your Conversations Stay Private
ChatGPT stores your data on OpenAI's servers in the US. Local ChatGPT with Open WebUI keeps everything on your own infrastructure. No data leaves your network unless you choose to route requests to an external API. GDPR-compliant when running in EU data centers. Your data is yours.
No Vendor Lock-In Ever
Open WebUI is open-source. You own the setup. You control the models. You can run Ollama locally, switch to a different interface, or use external APIs (ChatGPT, Claude, Mistral) all from the same UI. Want to migrate someday? Your data goes with you. No extraction penalty.
Built for teams who need reliability
How to Run Local ChatGPT in 4 Steps
Set up a private ChatGPT alternative in under 10 minutes. No command line required if using Opsily.
Choose Your App
Select an app to get started.
Install Ollama
Ollama is the runtime that powers local LLMs. It downloads and manages open-source models (Llama 2, Mistral, etc.). Think of it like Docker for AI models. Takes 3 minutes.
Deploy Open WebUI
Open WebUI is the ChatGPT-like interface. Connect it to your Ollama instance (or external APIs). Opsily handles this in one click—no Docker config needed.
Choose Your Models
Pick from 170+ open-source models. Start with Mistral 7B (fast) or Llama 2 13B (smarter). Swap models anytime. Mix local models with ChatGPT/Claude via APIs.
Invite Your Team
Share a single login link. Open WebUI handles multi-user access and role-based permissions. No per-seat licensing. Everyone uses the same instance.
The Local ChatGPT Stack
Open WebUI runs on top of Ollama. Together they form a complete ChatGPT replacement. Both are open-source and free.

Open WebUI vs ChatGPT: What You Actually Get
ChatGPT Plus pricing as of June 2026. Opsily Small plan ($20/mo) supports 3 apps; Medium ($40/mo) supports 5.
What You Need to Know About Local LLMs
Local language models like Llama 2, Mistral, and Phi run directly on your server. They're smaller than ChatGPT but fast enough for most work: summarizing documents, brainstorming, coding help, customer support.
The trade-off? Local models are not as smart as ChatGPT-4 on every task. But they're improving monthly. And for $0 upfront cost, the value is hard to beat.
Open WebUI solves the interface problem. It looks and feels like ChatGPT but connects to local models, external APIs, or both. You can use Mistral 7B for quick questions (it runs in seconds) and route complex queries to Claude for better reasoning.
When to Choose Local ChatGPT
Local ChatGPT makes sense if you:
- Have a team paying $20-40/month per person for ChatGPT
- Need GDPR compliance or EU data residency
- Want to avoid API rate limits or token costs
- Are willing to accept slightly slower/less advanced reasoning
- Need offline access or want to avoid cloud dependencies
Stick with ChatGPT if you:
- Need GPT-4 reasoning for complex analysis
- Are a solo user (single $20 sub is cheapest)
- Don't care about data privacy
- Want zero setup time
Why Open WebUI Wins vs Other Self-Hosted Options
Other local ChatGPT alternatives exist (AnythingLLM, LocalAI). But Open WebUI has the best user experience: RAG (Retrieval-Augmented Generation), markdown rendering, multi-user support, and OpenAI-compatible APIs. It's the most mature and fastest-growing open-source ChatGPT UI.

All plans include 30-day free trial, GDPR-compliant German hosting, automatic backups, and SSL certificates.
