Static Inbound & Outbound IPs for Vercel

While both Vercel and QuotaGuard utilize AWS infrastructure, the difference lies in exclusivity and scope. Whitelisting Vercel’s dynamic IP ranges opens your firewall to traffic from any user on their platform, which is a significant security risk.

QuotaGuard provides two dedicated static IPs that belong exclusively to your account, allowing you to lock your firewall down to your specific traffic alone.

Note that because these are cloud-based IPs, this solution is designed for professional B2B allowlisting and is not intended for accessing consumer sites that block all cloud-based ASNs.

Create a temporary API route that makes a GET request to https://api.ipify.org through the proxy.

The response will return the IP address detected by the remote server; it should match your assigned QuotaGuard Static IP.

Once verified, you can confidently provide this IP to your IT team to be allowlisted in the destination firewall.

Yes.

Vercel's native Secure Compute feature is a premium add-on typically locked behind expensive Enterprise contracts starting at hundreds of dollars per month.

QuotaGuard provides the same static outbound IP benefits at a significantly lower cost ($19/mo for the Micro plan) and works on all Vercel plan tiers, including Pro and Hobby.

Vercel serverless functions have a default maximum duration (e.g., 10 seconds for Hobby, 15 seconds for Pro) before they return a 504 FUNCTION_INVOCATION_TIMEOUT error.

Because routing through a proxy adds a small amount of network latency (typically 10–30ms), you should ensure your maxDuration in vercel.json or your page config is set high enough to account for the total round-trip time of your secure database or API calls.

Yes, however, Vercel recently updated its routing logic (specifically in Next.js 16+) to favor proxy.ts or middleware.ts at the root of your project.

While these are useful for lightweight request shaping, they are often executed at the "Edge," which has stricter memory and runtime limits.

For high-throughput B2B data syncing or complex database queries, we recommend routing from standard Serverless Functions where you have more control over the HTTP client configuration.

Absolutely. Vercel environment variables are encrypted at rest and only exposed during the build step or function execution.

We recommend adding your connection string as a "Secret" in the Vercel Dashboard and mapping it to a variable like QUOTAGUARD_STATIC_URL.

This ensures your credentials are never hard-coded in your source code and can be easily rotated or changed across different environments (Preview vs. Production) without redeploying your entire application.

Yes. By setting your QuotaGuard connection string as a proxy environment variable in your Vercel Project Settings, your build processes will route traffic through your static IP just like your serverless functions.

This is critical for applications that perform database migrations or fetch data for Static Site Generation (SSG) during the build phase, as it prevents your firewalled backend from blocking Vercel’s build servers.
