akcache.io - EU-Sovereign Databases: Managed Databases on Hetzner infrastructure. 5-minute setup.

Back in 2024, I got frustrated watching EU startups default to AWS/DigitalOcean for databases without thinking about what that means legally. The CLOUD Act gives US authorities access to EU data even when it's stored in EU regions. Most developers don't realize this until they're explaining it to a compliance officer. I'm Muhi, solo developer from Germany, and I built io-cache.io to fix this. The concept was simple: take Hetzner's solid infrastructure (which I already use), add proper database provisioning and management, keep it EU-only. The architecture evolved from "one server per customer" to multi-tenant when I realized the economics didn't work at scale. Turns out you can run 6 Redis instances on a single €3 Hetzner CX23 server if you isolate them properly. That's how we get to €7.99 pricing. Built the whole backend in C# with ASP.NET Core because I know it well and it's fast. Automated everything with the Hetzner Cloud API and SSH. Added Mollie for payments instead of Stripe because, again, EU-first approach. The timing turned out perfect - EU just announced the Cloud and AI Development Act aiming to triple EU data center capacity by 2030. Digital sovereignty is becoming policy, not just a nice-to-have. Right now it's just me running this. No investors, no runway pressure. Just trying to provide what I'd want to use myself: managed databases that don't compromise on where my data lives.
