The Math: ChatGPT Plus vs Open WebUI
Every month you run ChatGPT Plus or Claude Pro across a team, you're paying per person. ChatGPT Plus: $20/month per user. Claude Pro: $17/month annual or $20 monthly. Claude Team adds $20 per seat on top.
For a team of 50, that's $1,000 per month in per-user fees. For 100 people, $2,000. For 500, $10,000. Add this up over three years and you're looking at vendor lock-in with no way out except shutting down the tool.
Open WebUI flips the model. Pay once for infrastructure. Add as many team members as you need, unlimited. Your data stays on your servers. You control the models running inside. You control the audit logs. You control the data retention policy.
DevOps teams, healthcare providers, and fintech companies switched not because Open WebUI is trendy. Because it's $10,000+ cheaper per year and more secure than the alternative.
Common Questions
