Add basic middleware to your api/index.js file to prompt for a password before granting access to the proxy engine.
Start by creating a new directory and initializing your project:
These examples show that the pattern of running a proxy on Vercel extends far beyond Node Unblocker specifically. Once you understand the mechanics, you can adapt the approach to almost any proxying requirement.
Every time a user makes a request through your Vercel proxy, the target site sees the IP address of the Vercel Edge Network or AWS Lambda instance handling that specific request. Because Vercel dynamically assigns nodes, your proxy's outward-facing IP may change frequently. This is excellent for masking identity but can trigger security captchas on sites like Google or Cloudflare. Best Practices and Security Considerations node unblocker vercel
Because serverless functions are stateless, cookie-based sessions on target websites can break if headers are not handled correctly. Ensure your unblocker configurations pass standard cookie headers seamlessly back to the client browser. 3. IP Rotation and Geolocation
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
// Initialize the unblocker with custom configurations const unblocker = new Unblocker( prefix: '/proxy/', // The path where the proxy listens requestMiddleware: [ // Optional: Modify requests before they are sent (req, res, data) => // Add custom user-agent to avoid being blocked data.headers['User-Agent'] = 'Mozilla/5.0 (compatible; MyProxy/1.0)'; return data; Add basic middleware to your api/index
To get these features working correctly on Vercel, you must include a vercel.json file in your root directory to configure the and define your routes. Using the Node.js Runtime with Vercel Functions
That said, many developers still use Vercel for or for very low‑traffic personal proxies . If you plan to use a proxy for serious production work, consider platforms that explicitly allow proxies, such as:
Ever sat down at your local coffee shop, fired up your laptop to check a site, and been met with a cold "Access Denied" message? It's frustrating. Every time a user makes a request through
generally prohibit using their infrastructure for "malicious activity" or "bypassing security controls." Proxies often fall into these categories, leading to account bans or blocked deployments IP Reputation
Node Unblocker works beautifully for standard websites with traditional HTML, CSS, and JavaScript. But more sophisticated sites may break.
on Hobby plans), which can cause large pages or slow-loading sites to fail during proxying. Policy and Security Considerations
