Netlify Edge Functions Cloaking: Jamstack Traffic Filtering for Modern Funnel Sites

How Netlify Edge Functions enable cloaking for Jamstack funnels — geo routing, middleware patterns, and where Cloaker.net completes the picture.

Netlify Edge Functions Cloaking: Jamstack Traffic Filtering for Modern Funnel Sites

Netlify Edge Functions Cloaking

Jamstack traffic filtering for modern funnel sites — and the missing intelligence layer.

Jamstack funnels need filtering too

A huge number of affiliate landing pages, comparison sites, and lead-gen funnels are Jamstack builds: Astro, Eleventy, Hugo, or plain HTML deployed on Netlify. Static sites are fast and cheap — but they're also wide open: every bot, scraper, and ad reviewer sees the same HTML as your best customer. Netlify Edge Functions are the natural place to fix that, running Deno-based code on every request before your static content is served.

The DIY pattern on Netlify

export default async (request, context) => {

  const country = context.geo?.country?.code ?? '??';

  const ua = request.headers.get('user-agent') ?? '';

  if (country === 'XX' || BOT_UAS.test(ua))

    return context.rewrite('/safe');

  return context.next();

};

Geo rewrites and simple UA filters work out of the box. But like every DIY edge setup, the intelligence decays: ad review bots rotate ranges, spoof UAs, and increasingly emulate real browser behavior. A Netlify Function can route traffic — it can't reliably classify it, week after week.

Completing the stack with Cloaker.net

🧩 In-function classification

Call the Cloaker.net API from your Edge Function and rewrite based on its verdict — your routing stays in your codebase.

🛡️ Upstream protection

Or point ad URLs at a Cloaker.net-protected domain entirely — bots never even reach your Netlify site, saving bandwidth and keeping analytics clean.

Either way, you get what no hand-written Edge Function delivers alone: ad-platform-specific bot intelligence, AI behavioral detection, minute-level database updates, and per-visit logs. Jamstack speed + Cloaker.net intelligence = funnels that convert humans and baffle bots. Start at cloaker.net.

Static-site speed. Cloaker-grade security.
