Usage: append /proxy/HTTPS://TARGET-WEBSITE.COM to the URL.
Some highly interactive web applications will break or partially expose your real IP address when executing client-side JavaScript. Platform Terms of Service and Abuse Policies
: Check your Vercel dashboard regularly to monitor serverless function execution times and bandwidth consumption. This helps avoid unexpected plan upgrades or account suspensions.
Before beginning the installation, ensure you have the following assets ready: A account. A Vercel account linked to your git provider. Node.js (v18 or higher) installed locally for testing. node unblocker vercel

Streaming a large video or loading a complex web app through a Node Unblocker will hit these limits in seconds. The proxy will crash or time out constantly.
Initialize your project and install the core unblocker package along with compatible midleware handlers. Usage: append /proxy/HTTPS://TARGET-WEBSITE
const express = require('express'); const Unblocker = require('unblocker');
Node Unblocker operates by creating a customizable web server. When a user accesses the proxy via a specific URL prefix (e.g., your-site.vercel.app/proxy/ ), the server intercepts the request, fetches the content from the destination website, and rewrites any links, cookies, or other resources so they continue to work through the proxy. This process ensures a seamless browsing experience for the user, often without them even realizing they are using a proxy.
: Vercel runs code as Serverless Functions , meaning the proxy only "exists" when a request is made, making it highly efficient. This helps avoid unexpected plan upgrades or account
To help me tailor this setup to your specific project, tell me: Are you building this for or a larger audience ? Also, do you need the proxy to handle complex JavaScript-heavy websites , or just basic data and text retrieval ? Share public link
: Vercel's hobby tier caps serverless function execution at 10–15 seconds. If you try to stream large video files or download massive datasets through the proxy, the function will time out and drop the connection.
