Cloudflare

ELI5 — The Vibe Check

Cloudflare is like a superhero shield in front of your website. It makes your site load faster everywhere in the world, protects you from hackers and DDoS attacks, and does a million other things at the 'edge' (close to your users). Also their free tier is shockingly generous.

Real Talk

Cloudflare is a global cloud network providing CDN, DDoS protection, DNS, SSL/TLS, edge computing (Workers), serverless storage (R2, KV, D1), and Zero Trust security. It operates one of the largest networks in the world with 300+ data centers globally.

Show Me The Code

// Cloudflare Worker — run code at the edge
export default {
  async fetch(request) {
    return new Response('Hello from the edge!', {
      headers: { 'Content-Type': 'text/plain' }
    });
  }
};
