Our mission

Breaking the
Fluent mold.

Windows has incredible power under the hood, but standard Fluent controls only go so far. ModernApp Labs exists to build what is next. We take the high-performance engine of WinUI 3 and build completely custom, non-Fluent interfaces on top of it.

Whether it is a minimalist aesthetic or a completely bespoke canvas, we override default templates to prove that native Windows apps do not have to look like default Windows apps.

Why hire us

We don't just write code.
We design for the platform.

01

WinUI 3 at the core

We build on Microsoft's modern UI framework. Not wrappers, not Electron. Native performance, native integrations, native everything.

02

Custom UI, not Fluent defaults

We override control templates and craft layouts beyond what the design system allows. The result looks like nothing else on Windows.

03

Performance by design

Lightweight and responsive. We optimize render paths and keep resource footprint minimal. No unnecessary overhead.

04

Privacy without compromise

No telemetry beyond OS requirements. Your data stays on your machine. That is not a feature, it is the baseline.
