Cloudflare + Tailscale + Ollama: Build a Production Stack for $0

Three services. Zero cost. Production-grade infrastructure. This stack has been running production side projects serving thousands of daily active users for exactly zero dollars.

The Stack

Layer	Service	Cost
Frontend	Cloudflare Pages	$0
Backend	Cloudflare Workers	$0 (100k req/day)
Database	Cloudflare D1	$0 (5M reads/day)
Storage	Cloudflare R2	$0 (10GB)
Networking	Tailscale	$0 (100 devices)
AI Inference	Ollama	$0 (your hardware)

Total: $0/month.

Why This Works

Cloudflare handles the public face — static sites on Pages, APIs on Workers, SQL at the edge via D1. Tailscale connects your private machines through a WireGuard mesh VPN with zero configuration. Ollama runs open-source LLMs on your own hardware with an OpenAI-compatible API.

Getting Started in 10 Minutes

1. Deploy to Cloudflare

npx wrangler pages deploy dist/
npx wrangler deploy

2. Set Up Tailscale

curl -fsSL https://tailscale.com/install.sh | sh
tailscale up

3. Run Ollama

curl -fsSL https://ollama.com/install.sh | sh
ollama pull llama3.2:3b
ollama serve

4. Connect Everything

Your Worker connects to Ollama over your Tailscale network:

export default {
  async fetch(request, env) {
    const OLLAMA_URL = 'http://tailscale-ip:11434/api/generate'
    const response = await fetch(OLLAMA_URL, {
      method: 'POST',
      body: JSON.stringify({
        model: 'llama3.2:3b',
        prompt: 'Analyze this code: ' + await request.text(),
        stream: false
      })
    })
    return response
  }
}

The Verdict

You do not need a $100/month cloud bill to run a production application. Cloudflare for edge hosting, Tailscale for private networking, and Ollama for local AI — all free, all production-grade.
