Self-Hosted ChatGPT UI: Run Open WebUI Your Way
154k developers use Open WebUI to build their own ChatGPT-like interface. No per-seat licensing. No data training by default. But setup and maintenance have a real cost. Here's the honest comparison.
The Real Cost of Self-Hosting Open WebUI
Open WebUI runs on Docker. You spin up a VPS ($5-20/month on Vultr or DigitalOcean). Configure networking. Update the image every few weeks. Back up your chat history. Monitor uptime.
For a single developer: worth it.
For a team of five? You're now a part-time DevOps engineer.
For a team of ten? You're paying yourself to solve infrastructure problems.
What You Actually Need
- A Linux VPS ($5-20/month)
- Docker installed (30 minutes)
- Persistent storage for conversations
- SSL certificates (free via Let's Encrypt, but you manage renewal)
- Regular updates to patch security issues
- Monitoring so you know when it fails at 2am
- Backups in case the host fails
None of this is hard. All of it is overhead.
DIY Open WebUI Setup in 10 Minutes

Annual Hidden Costs (DIY)
Fixed hosting costs:
- VPS: $60-240/year
- Domain: $12/year
Your time (unquantified):
- Initial setup: 3-5 hours
- Maintenance: 6-12 hours/year
- Troubleshooting: variable
If you bill at $100/hr: $900-1,700 in labor.
Total real cost: $972-1,952/year.
Plus the stress of 2am alerts and lost backups.

Frequently Asked Questions
Yes. Open WebUI is a web interface that connects to any LLM (Ollama for local models, or OpenAI/Claude APIs for cloud). It's BSD-licensed and runs on Docker. You get a ChatGPT-like interface without ChatGPT's per-user subscription ($20/month each). For a team of 10, that's $200/month. Open WebUI DIY costs $5-20/month for VPS hosting plus your setup and maintenance time. The catch: you host it yourself, which means updates, backups, monitoring, and 2am alerts are your job. That's where managed hosting on Opsily comes in: same Open WebUI, zero DevOps overhead.
