Hi everyone!
As developers, we know how expensive SaaS APIs can get. Address validation is one of those silent killers—it starts cheap, but as your app grows, you find yourself paying $100, $500, or even $2,000 a month just to verify where your users live.
I decided to fix this for my own projects, and today I'm sharing the result: Global Address Finder PRO.
Why Self-Hosted?
By self-hosting your address validation, you get:
- Zero latency: The data is right there in your infrastructure.
- Data Privacy: Your user addresses never leave your server.
- Fixed Cost: No more "pay-per-request" anxiety.
The Tech Stack
I chose these tools for maximum performance:
- FastAPI: Because it's lightning-fast and provides automatic Swagger docs.
- Redis: Used as a high-speed cache layer for instant lookups.
- Docker: So you can deploy the entire stack with a single command.
How it works
The tool is designed to be a "drop-in" replacement for more expensive services. You spin up the container, and you're ready to go in under 5 minutes.
🚀 Get Early Bird Access
I’ve just launched the PRO version for developers who want to own their infrastructure. It's currently available for a one-time payment of $29 (Early Bird).

I'm looking for honest feedback!
- Does this stack fit your workflow?
- What regions would you like to see supported next?

Thanks for reading! I'm really looking for honest feedback on the deployment process. If anyone has specific questions about the Redis implementation or the dataset, feel free to ask here!
