| Alternative | Platform | Legality | Use Case | |-------------|----------|----------|-----------| | | Any | ✅ Legal | Fetch data directly from browser | | Official VPN | Your own device | ✅ Legal (if allowed) | Bypass network restrictions for yourself | | Self-hosted proxy | VPS (DigitalOcean, Hetzner) | ⚠️ Gray area (ToS may prohibit) | Full control, but need own server | | Cloudflare Workers | Cloudflare | ✅ Legal (within ToS) | Lightweight proxy for specific origins | | CORS Anywhere (self-hosted) | VPS | ⚠️ Same as Node Unblocker | Similar functionality | node unblocker - codesandbox

| Detection Method | How it works | |----------------|---------------| | Outbound request patterns | High volume of unique domains from one sandbox | | User-Agent analysis | Proxy often leaks Node Unblocker default headers | | Content inspection | HTML rewriting adds proxy prefixes ( /proxy/http:// ) | | Behavioral heuristics | Repeated requests to http:// sites from HTTPS sandbox | | Resource monitoring | CPU/memory spikes from request rewriting | Run: node server

Use a local Node Unblocker on your own machine ( localhost ), not on a public cloud IDE. 8. Step-by-Step: Running Node Unblocker Locally (Safe) If you need to test the proxy behavior: const Unblocker = require('node-unblocker')

mkdir test-proxy cd test-proxy npm init -y npm install express node-unblocker Create server.js :

const express = require('express'); const Unblocker = require('node-unblocker'); const app = express(); const unblocker = new Unblocker( prefix: '/proxy/' ); app.use(unblocker); app.listen(3000, () => console.log('Proxy running at http://localhost:3000/proxy/'); );
