How We Built rnsu.net
$5,000 infrastructure. $0/month in cloud AI. Here is exactly how.
Numbers above are pulled live from this site's backend — refresh to re-fetch.
Local hardware costs are one-time, not metered. No surprise overage when traffic spikes.
No customer text, document, or query is sent to a third-party AI service. Helpful when compliance, privacy, or trust matters.
Models swap in and out. If a better one ships next quarter, we use it. You're not married to one provider's pricing or roadmap.

Architecture
How every request flows from your browser to local AI and back
When you visit www.rnsu.net:
- Cloudflare Pages serves the static site (HTML, CSS, JS) — globally cached, fast everywhere
- When you use the chatbot, your message goes through a Cloudflare Worker (CORS proxy)
- The Worker forwards to our local server via Cloudflare Tunnel
- Our FastAPI backend sends your message to LM Studio running a Qwen 3.5 model
- The AI response comes back the same path — your data never touches a cloud AI service
What This Would Cost on Cloud

Every MIA project follows this same philosophy
verified Build once, own forever
No subscriptions, no vendor lock-in. You own the infrastructure and the code. Walk away anytime with everything you paid for.
dns Local-first
Your data stays on your hardware. We default to local deployment because it saves money and gives you control over your information.
cloud_done Cloud when it makes sense
Azure for global scale, compliance, or disaster recovery. We have 5+ years of cloud experience when the situation calls for it.
