Engineering studio for software and digital craft
From web platforms and connected devices to Rust, graphics, and IoT integrations — Löwenware helps product teams deliver complex software and recover projects that have gone off track.
Our core strengths
Where we make the biggest difference for product teams.
End-to-end product engineering
Design, build, and ship web and mobile applications with senior engineers who work directly on your product — no agency layers.
Connected devices and integrations
Bridge cloud software with embedded systems, protocols, and IoT hardware — from BLE stacks to protocol converters and device management.
Rust, graphics, and performance
Specialist engineering for performance-critical systems — Rust, real-time graphics, GPU-driven rendering, and low-level systems work.
Stabilization and modernization
Take over delayed or troubled codebases, assess the situation honestly, and get delivery back on track with a focused first sprint.
Trusted by product teams
Engineering in the real world — client projects we are proud of.

Independent by design
Work for customers is the foundation of Löwenware. It lets us build deep engineering experience across real products, complex systems, and long-term partnerships.
We reinvest that capability into our own product engineering and research—from Dotrix to Löwenbooks and Mythstic. Because we grow through the work we deliver rather than loans or external investments, we can pursue ideas patiently, keep technical decisions in our hands, and build for the long term.
The cycle benefits both sides: client challenges sharpen our practice, while our own products keep us close to the consequences of the engineering decisions we make.
Our products
Products we build alongside client work — evidence of what we can deliver.
Löwenbooks
LiveOnline e-books marketplace - a platform where authors, publishers, and readers connect.
Dotrix
Open sourceOur in-house open-source Rust 3D engine — modular, performant, and built for real-time graphics.
Mythstic
Early conceptOur first game project — currently in early concept development, built on Dotrix.
From our engineering notebook
Technical writing on Rust, systems, and software engineering.
