Hey Product Hunt !

I m Leon, a 15-year-old self-taught developer from France , and I m super excited to share UtiliNexus with you today!

Instead of building one massive, bloated app, I wanted to create specialized, lightweight web tools for different needs from group trip planning (HolidayHub Elite) and movie choosing (Meldova) to offline hiking (Cairn) and party games (Clandestio).

UtiliNexus is the bridge between all of them: one single account to seamlessly log into the entire ecosystem, while every tool keeps its own unique identity and design.

Has anyone here rebuilt something they use daily because the official product has a quirk / bug that annoys you?
For example - I use Termius to connect to servers over SSH but on my Ubuntu 26 Desktop, Termius is buggy to the point of being unusable.
So - I recreated it using Claude, with one or two improvements. Now I run my version in Docker whenever I need to use it.

I ve been building my app mostly with AI coding tools, and the experience has been pretty weird.

At first, it feels almost like cheating.

You describe a feature AI writes it you test it repeat.

But once the app gets bigger, the problems change.
