Supports middleware for tasks like rotating user agents or removing Content Security Policies (CSP).
: Because Vercel uses dynamic IP addresses and reputable domains (e.g., *.vercel.app
This is the . It tells Vercel to treat your index.js as a routing gateway.
const express = require('express'); const Unblocker = require('unblocker'); const app = express(); const unblocker = new Unblocker( prefix: '/proxy/' ); // The unblocker middleware must be used before other routes app.use(unblocker); app.get('/', (req, res) => res.send('Node Unblocker is running. Use /proxy/https://google.com to start.'); ); module.exports = app; Use code with caution. Copied to clipboard 3. Vercel Configuration ( vercel.json )
A Node Unblocker is a web proxy utility used to bypass network restrictions, mask IP addresses, and access blocked web content. While traditionally hosted on dedicated servers or VPS environments, pairing Node Unblocker with Vercel offers a powerful, serverless solution. Vercel provides an exceptionally fast global CDN, automated deployments, and a generous free tier. node unblocker vercel
Do not share your proxy source code publicly with the Vercel deployment button attached.
Setting up Node Unblocker on Vercel is a straightforward process. Here's a step-by-step guide:
Create a clean directory for your project. You will need a backend API route and a configuration file.
When deploying a Node Unblocker instance on , the most valuable feature you can implement is custom middleware for request/response manipulation . Since Vercel uses a serverless architecture, these features help maintain the proxy's functionality and performance. Recommended Features for Node Unblocker on Vercel Supports middleware for tasks like rotating user agents
Request and response sizes are limited to 4.5 MB.
Initialize a Node.js project and install node-unblocker along with a serverless-friendly framework like Express (which Vercel natively supports inside serverless functions).
The nodeunblocker.com package allows for modifications to handle specific site restrictions.
You need to tell Vercel to route all traffic to your script so the proxy can handle different URLs: Vercel Configuration ( vercel
Explore rewriting parts of the script to leverage Vercel's Edge Functions instead of Serverless Functions. Edge functions have no cold starts and operate closer to the user, although they have a stricter API runtime limit that may conflict with Node Unblocker’s native dependency on certain Node.js core libraries. Conclusion
Because Vercel treats files inside the api/ directory as serverless endpoints, you must structure your project specifically for their platform.
While deploying a node unblocker on Vercel is effective for simple browsing, it is important to understand its limitations. 1. Vercel Serverless Constraints

Vercel is a favorite host for these projects for several reasons:
Vercel needs to know how to handle the serverless function. You may need to create a vercel.json file in the root directory if one is not already present, defining the app as a Vercel Function:
