Static IP for Supabase Edge Functions

Static IP for Supabase Edge Functions - Reliable SOCKS5 Connectivity for Deno Runtimes and Global Edge Clusters.

Supabase Edge Functions, powered by Deno, run at the network's edge for low-latency performance. However, connecting to secure third-party services often requires a static IP for whitelisting.

QuotaGuard's Static plan provides a straightforward SOCKS5 proxy on port 1080, which is natively supported by Deno.

This allows your edge functions to route traffic through dedicated static IPs without needing complex tunneling tools or sidecar processes that aren't supported in the edge environment.

Bridging Supabase Edge Functions to Enterprise Security

Overcoming Runtime Restrictions in Distributed Edge Environments

While traditional cloud environments allow for the use of sidecar processes or background binaries like QGTunnel, the sandboxed Deno runtime used by Supabase Edge Functions prohibits these methods.

This necessitates a lightweight, protocol-level solution that operates within the constraints of a serverless edge worker.

QuotaGuard Static resolves this by exposing a cloud-native SOCKS5 gateway, providing the persistent IP identity required to traverse enterprise firewalls without requiring any infrastructure changes to your Supabase project.

Integration Workflow: Supabase Edge Functions

This workflow outlines the technical steps to route your Supabase Edge Functions through QuotaGuard's high-availability SOCKS5 gateway.

By leveraging native Deno proxy support, you can establish secure, whitelisted connections to external APIs and databases using only standard environment variables and connection logic.

1. Provision QuotaGuard Static

Sign up for a QuotaGuard Static plan.

Unlike the Shield tier, which defaults to advanced E2EE tunnels, the Static tier provides the standard SOCKS5 proxy necessary for Deno-based environments.

2. Add Your Static IPs to the Allow-List

Retrieve your two dedicated Static IPs from your QuotaGuard dashboard.

Add these IPs to the firewall or "Network Access" settings of the destination service (e.g., MongoDB Atlas, SQL Server, or a third-party API).

3. Configure the Deno Proxy

In your Supabase Edge Function, initialize your HTTP client or database driver to route through the QuotaGuard SOCKS5 endpoint.

Since Deno supports this natively, you simply provide your QuotaGuard credentials and proxy address (port 1080) directly in your connection logic.

FAQs

Technical Configuration and Setup for Supabase Edge Functions

Why shouldn't I use QuotaGuard Shield with Supabase Edge Functions?

QuotaGuard Shield is designed for E2EE (End-to-End Encryption) via secure tunnels like QGTunnel or QGPass.

Supabase Edge Functions operate in a sandboxed Deno runtime that does not allow the execution of background binaries or sidecar processes.

QuotaGuard Static is the correct choice because it offers a plain SOCKS5 proxy that Deno can interact with using standard web protocols.

Does this setup require any external binaries?

No.

One of the primary advantages of this integration is that it requires no tunnels or sidecar processes.

The connection is handled purely at the application layer within your Deno code, making it compatible with the lightweight execution model of Supabase's edge infrastructure.

Can I whitelist my Supabase database directly?

Supabase projects have configurable Network Restrictions for their PostgreSQL databases.

However, if your goal is to have traffic leaving a Supabase Edge Function and entering another secure system, you need the static outbound identity that QuotaGuard provides.

What is the latency impact of routing through the edge?

Supabase Edge Functions are distributed globally to be near your users. To minimize latency, QuotaGuard offers proxy nodes in all major global regions.

By matching your QuotaGuard gateway region to your Supabase project's primary region, you ensure that the "network hop" is optimized for performance.

How do I authenticate requests to the QuotaGuard proxy from a Supabase Edge Function?

Authentication is handled via the credentials embedded in your QUOTAGUARDSTATIC_URL.

When configuring your Deno fetch or database client, you must extract the username and password from this environment variable and include them in the Proxy-Authorization header or the proxy configuration object.

This ensures that every request leaving the Supabase edge is verified by the QuotaGuard gateway before being assigned a static IP.

Does QuotaGuard Static support non-HTTP traffic from Supabase Edge Functions?

Yes, the QuotaGuard Static SOCKS5 gateway supports any TCP-based protocol, including direct database connections (e.g., PostgreSQL or MySQL) and custom API protocols.

Because Supabase Edge Functions allow for outbound TCP connections via Deno's networking APIs, you can route non-HTTP traffic through the proxy on port 1080 without the need for additional tunneling software.

How do I manage different QuotaGuard environments (Development vs. Production) within Supabase?

You should utilize Supabase’s Environment Variables (Secrets) to manage distinct QuotaGuard credentials for different project stages.

By setting a unique QUOTAGUARDSTATIC_URL for your staging and production branches, you can route traffic through separate static IP pairs.

This allows you to maintain independent allow-lists on your destination servers, ensuring that development traffic never originates from your production IP identity.

We've been using QuotaGuard Static for nearly six years to provide static IP addresses to our clients so they are able to whitelist our network traffic.

The service has been hassle free, has never "not worked" or had any downtime to my knowledge. The only time we've reached out to support was during a migration from one cloud provider to another to ensure that we wouldn't cause interruptions in the service ourselves. The service we received at that time was prompt and professional.

The app's backend runs on serverless functions, and the railway data provider I was using only accepted requests from a fixed IP address. QuotaGuard gave me exactly that, and my passengers' PNR status checks kept working.

I used QuotaGuard Static IPs for ClearBerth, my train app for Indian Railways passengers. The app's backend runs on serverless functions, and the railway data provider I was using only accepted requests from a fixed IP address. QuotaGuard gave me exactly that, and my passengers' PNR status checks kept working.

It helped me because I could keep building the app without worrying about how to get a static IP. For a solo developer that is a real relief.

The best thing about QuotaGuard is the owner himself. Michael is kind, thoughtful and genuinely warm. When I wrote to say thank you, he replied personally, said it made his Sunday morning, and offered a returning customer discount for any future project. You do not often get that from a service company. I would happily use QuotaGuard again and I recommend it to any developer who needs a static IP.

QG helped us prove our pipeline and workflow with users and in the end, we would have stayed but we use AWS for all our production so we had to switch. Sorry to go but loved every minute of it!

QUOTAGUARD FTW! We used qg for spooling up a prototype that needed access to MongoDB through Heroku without having to use 0.0.0.0 in mdb whitelist. Big nono for privacy and security. QG helped as we were able to add it as a resource in Heroku and test our prototype. As the platform matured, more test users came on board and our bandwidth scaled to a point where we were no longer a prototype so we moved over to AWS which is where our production apps live. The team at QG is beyond awesome. I sent an email and I think within 24hrs or less we had solved the issues with Tim and Michael. The fact they didn't pester after signup was refreshing as well. They are Dev dev's who get it. QG helped us prove our pipeline and workflow with users and in the end, we would have stayed but we use AWS for all our production so we had to switch. Sorry to go but loved every minute of it!

I needed to configure a static IP address for my app running on Heroku, so I could connect to an external database in a more secure manner. A colleague recommended Quotaguard as an option.

The product works great - but where they really shine is the exceptional customer service. One of my background workers was sneakily polling, which didnt show on the logs, and the Quotaguard support team showed patience and knowledge helping me get to the root of the problem. Fantastic team.

Solid service. :) Does what's on the tin. They know what they're doing, and I mean that in two ways: (1) their execution of their value offering is *solid*, and (2) they appear undistracted by things that *aren't* what they're doing. A "small, sharp tools", you know?
