About Us

A small studio with deep roots

ivystudio is an independent Czech studio that builds two kinds of software: serious tools for musicians, and games. Both grow from the same root — a habit of owning the whole stack, from the rendering engine and audio DSP to payments and deployment.

We have been making games since 1996. In 1998 we shipped 3D Crackanoid Ultra for Windows on our RVL3 engine. That engine lived on, and today it is ivyspace: modern C++ on Metal and Vulkan, running on iPhone, iPad, Mac, Apple TV, Windows and Android.

On the music side, MusicTrainerPro brings structured practice with real instrument feedback, and One Music Online gives every musician free tools in the browser. Like ivy, we grow slowly, hold on tight, and stay for a long time.

Our Engine

ivyspace: 30 years of 3D, rebuilt for today

ivyspace is our own real-time 3D engine. It began life as RVL3 / Crash3D on DirectX for Windows, and has been carried forward onto a portable GPU layer with Metal and Vulkan backends, SDL3 for windows and input, and OpenAL for sound.

Owning the engine means our games run natively everywhere we want them — and old games come back to life instead of disappearing with the platforms they were written for.

How We Work

Built serious, operated smart

We own the hard parts. That keeps us small, fast, and independent.

Real Instrument Input

MIDI devices and microphone pitch detection deliver genuine feedback — not tap-the-screen gamification.

Own 3D Engine

ivyspace renders natively through Metal and Vulkan, so our games feel at home on every device.

Every Screen

Phone, tablet, computer, TV. Layouts adapt to the screen and controls follow the device you hold.

AI-Augmented Operations

Content, localization, store listings and support are automated, so a small team can ship like a large one.

Privacy by Design

Built under EU law with GDPR in mind. Our game collects no personal data at all.

Low-Cost Architecture

Lean servers, containerized deploys, CI/CD via GitHub Actions. Software margins from day one.
