Inside api/proxy/[...path].js, we will use http-proxy-middleware or a native fetch relay. For extra quality, we need robust error handling.
// api/proxy/[...path].js
const createProxyMiddleware = require('http-proxy-middleware');
// Clean headers to avoid detection (Extra Quality)
const cleanHeaders = (proxyReq, req) =>
proxyReq.removeHeader('X-Forwarded-For');
proxyReq.removeHeader('Via');
proxyReq.removeHeader('CF-Connecting-IP');
proxyReq.setHeader('User-Agent', 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) ...');
;
module.exports = createProxyMiddleware(
target: 'https://', // Target is dynamic, we override it
changeOrigin: true,
secure: true, // Validate SSL certificates
router: (req) =>
// Extract the real URL from the request path
// Example: /api/proxy/https://example.com -> https://example.com
const url = req.params.path.join('/');
return url.startsWith('http') ? url : https://$url;
,
onProxyReq: cleanHeaders,
onError: (err, req, res) =>
res.status(500).json( error: 'Proxy quality failure', details: err.message );
,
// Extra Quality: Increase timeout for slow sites
proxyTimeout: 30000,
followRedirects: true,
logger: console,
);
Why this is "extra quality": It strictly cleans headers, handles dynamic routing, and includes a 30-second timeout (Vercel default is 10s, we request an extension).
Bypassing your school or employer’s acceptable use policy can lead to disciplinary action. In some jurisdictions, circumventing geo-blocks may violate terms of service for streaming platforms.
Before sharing your unblocker, run these tests:
Most free online proxies are terrible. They are slow, inject pop-up ads, steal cookies, and often fail on HTTPS sites. "Extra quality" is the standard that separates a hobby script from a professional tool. Here is what extra quality looks like in a Vercel unblocker:
Deploying the basic proxy is easy. Making it exceptional requires three advanced modifications.
Low-quality unblockers send 1,000 requests per second from a single Vercel IP, triggering immediate blocking.
The Extra Quality Solution:
Implement per-domain queuing using Vercel KV (Redis).
