1. Intro: The Problem
If you've ever tried to integrate your SaaS with an external API — Stripe, Salesforce, HubSpot, MongoDB Atlas — you've probably hit the same wall I did:
They ask you to whitelist your IP address.
But if you're running on modern platforms like Fly.io, Heroku, Vercel, or AWS Lambda, your outbound IP changes constantly. One day the integration works fine, the next day it silently fails because the IP rotated.
For EU startups, there's another layer: GDPR compliance and data sovereignty. Many existing static IP solutions are hosted in the US, which means your traffic leaves the EU. That raises questions during security reviews and can cause headaches with customers who demand EU-only data flows.
This frustrated me enough that I built my own solution.
2. My Motivation
I've been working in infrastructure and DevOps for years, and I kept seeing teams run into the same problems:
- API requests failing because of IP changes.
- Complex workarounds with VPNs, NAT gateways, or enterprise-only tools.
- Nervous conversations during security audits: "Where exactly do your API calls originate from?"
Existing services like QuotaGuard or Fixie solve the static IP problem, but they're not EU-first. Most are US-based, and they don't always take GDPR or European sovereignty seriously.
I wanted something different:
- A service that just gives you a stable outbound IP.
- Hosted entirely on EU servers.
- Built from day one with GDPR compliance in mind.
- With no packet sniffing, no hidden data collection — just encrypted passthrough traffic.
So I decided to build it.
3. What I Built
The service is a static outbound SSL proxy, designed for EU startups and SaaS teams.
How it works: You connect your app (from Fly.io, Heroku, Vercel, AWS Lambda, etc.) to the proxy. Your traffic goes out through a dedicated static IP hosted in EU data centers.
- You can give that IP to Stripe, Salesforce, MongoDB, or any other API that requires whitelisting.
- Everything is end-to-end encrypted — I don't (and can't) see your API data.
- Traffic is processed and stays inside the EU, ensuring data locality and sovereignty.
It's minimal on purpose: reliable, fast, GDPR-friendly, and EU-native.
4. Who It's For
This service is perfect for:
- Startups that need to integrate with APIs requiring IP whitelisting.
- SaaS teams who want to pass security reviews by showing fixed outbound IPs.
- Developers on Fly.io, Vercel, Heroku, or serverless platforms who don't want to hack together NAT gateways.
- EU companies who want their traffic to stay in-region for sovereignty, compliance, and peace of mind.
If you've ever had an API integration break overnight because of an IP change, or worried about US-based proxies in your GDPR audit, this is for you.
5. What's Next
This project starts with EU-based static outbound IPs.
From here, I'll:
- Add more regions as people ask for them.
- Publish practical guides on outbound proxies (how to use them with Fly.io, Heroku, AWS Lambda, etc.).
- Keep things simple, transparent, and developer-friendly.
My goal is to make sure EU startups have an easy, compliant way to handle outbound static IPs without paying for bloated enterprise solutions.
6. Call to Action
If you're an EU startup and need a GDPR-friendly, EU-native static outbound IP, you can try it free today.
The service is in early access, and I'd love your feedback:
- Does it solve your problem?
- What integrations should I cover next?
- What features would make this essential for you?
