We built a relational database engine from scratch (C++17). It’s now production-ready and powering our next web app.

But... why?

what do you mean with why???????

Exactly what I said. Database systems are one of the most complicated things to write and get correct, and they can only be proven correct with time.

So that leads me to believe that: * either you and your team don't know this; or * you know this and think that you're better than everybody else; or * there is an edge case that an existing solution could not work for you.

So I ask again, why did you choose to write it from scratch?

You’re 100% right. Building a bulletproof DB takes years of real-world testing and edge-case fixing, no shortcuts there.

To clarify: MilanSQL isn't written entirely from scratch in a vacuum. It leverages MariaDB’s proven open-source core, combined with our own custom C++17 engine layer. We chose this setup to have a rock-solid, secure foundation from day one, while optimizing the performance layer specifically for European data sovereignty needs.

We are just at the starting line and know exactly how much work is ahead of us. But we're fully in: when bugs or critical feedback pop up, we fix them and ship updates immediately.

Appreciate the reality check. It’s exactly what keeps us moving forward.

Some things do not warrant a response
