Qt Development Servicesfor Software That Runs on Hardware.
Most Qt development services stop at demos. We ship it into production — automotive dashboards, medical device interfaces, industrial HMIs, and desktop applications where C++ performance isn't a marketing line, it's the actual requirement. Built for teams whose software runs on real hardware, not just in a tab.

Why Entalogics for Qt
Four problems every
inherited Qt codebase
has.
Qt gives you more than most teams ever touch. The codebases we take over usually use about a third of it — C++ doing layout work, QML bolted on as an afterthought, a signal graph nobody can trace anymore.
Performance01
C++ was drawing pixels it should never have touched.
Heavy computation, hardware I/O, real-time logic — that's C++'s job. Animation, touch, layout — that's QML's. Blur the line and both get slower and harder to maintain at the same time.
Architecture02
The model layer and the view layer had no real boundary.
Q_PROPERTY and Q_INVOKABLE expose typed C++ models; QML binds to them declaratively. No business logic hiding in QML JavaScript, no UI code creeping into C++. Two engineers can work the same feature without colliding.
State03
Four hundred signal/slot connections, and nobody could trace them.
Qt's signal/slot system is elegant right up until it isn't documented. Explicit connection types, no string-based connections, a signal graph someone can actually read — or the next engineer spends a week reverse-engineering state flow that should've taken an afternoon.
Type safety04
A QVariantMap was standing in for a real type.
Modern C++17/20, RAII, smart pointers, and QML interfaces built on typed models instead of loosely-typed maps. Change a property's type and the compiler catches it in C++, the IDE flags it in QML — nobody finds out at runtime.
When Qt, when not
Qt is a tool.
Not always the right one.
Qt is the most capable native cross-platform framework there is. It's also C++, and C++ punishes teams without the discipline for it. We'll say so on the first call if Qt isn't the right fit for your team.
PICK QT WHEN
- The UI runs on real embedded hardware — automotive, medical, industrial — not a browser
- Real-time visualization is the job — sensor feeds, trading floors, SCADA panels — where 60fps on actual hardware is the bar
- One C++ codebase needs to cover Windows, macOS, and Linux without shipping a bundled browser engine
- The product has a ten-year-plus lifespan, where Qt's LTS support genuinely outlasts most alternatives
CONSIDER ALTERNATIVES WHEN
- Your team writes TypeScript and the product is data-driven CRUD — Electron or Tauri get there faster
- The product is mobile-first — Flutter and React Native have deeper mobile ecosystems
- It's fundamentally a content-heavy web app — that's a browser's job, not Qt's
WE SAY NO WHEN
- "Qt for a web dashboard" — that's a browser problem wearing a Qt costume
- "We want Qt because C++ is fast" — speed without architecture is just fast spaghetti
- "Ship an HMI in three weeks, no hardware specs yet" — that ship has sailed

The playbook
Qt development patterns
we ship on repeat.
Patterns from production embedded and desktop Qt apps — not Qt Creator tutorials.
P01
QML for UI, C++ for everything else.
Declarative QML for layout, animation, interaction. C++ models exposed through Q_PROPERTY. A strict, testable boundary on both sides.
P02
Typed model/view separation.
QAbstractListModel subclasses with typed roles, no QVariantMap shortcuts. QML binds to strongly typed properties — a role change fails at compile time.
P03
CMake-first build system.
Qt 6 wants CMake, not qmake. Multi-target builds for desktop, embedded, and test, with CI running every platform in parallel.
P04
QTest and Squish for end-to-end coverage.
Unit tests on C++ logic, GUI automation on target hardware. CI on every PR, not just before release.
P05
Boot-to-UI under two seconds.
Minimal init, EGLFS renderer, precompiled QML cache, a splash screen while services spin up. Users see UI before the kernel's finished booting everything else.
P06
Incremental QML adoption.
Existing Widgets apps gain QML screens one at a time through QQuickWidget. No full rewrite, no shipping pause.
Signature case
An industrial control panel,
migrated from Qt 4 Widgets to Qt 6 QML.
A factory floor HMI on Qt 4.8 with Widgets — 12-second boot on the target hardware, a UI that couldn't be restyled without recompiling, no touch support, and a qmake build system that only one engineer understood. Migrated to Qt 6 with QML, EGLFS rendering, and CMake in 11 weeks. Boot-to-UI dropped to 1.8 seconds. Touch support added. Restyling now takes hours, not days.
Before
Qt 4.8 Widgets · 12s boot · no touch · qmake · restyle = recompile
After
Qt 6 QML · 1.8s boot · full touch · CMake · restyle = QML edit

Foundation + first screen
Qt 6 baseline, QML architecture set, C++ models wired, one production screen running on target hardware. Real frame times from the actual device.

FAQ
Questions we get on almost
every Qt call.
Widgets vs QML, upgrades, embedded hardware, training — in roughly the order people ask.QML for new projects — touch-friendly, animatable, and where Qt itself is investing. Widgets for existing desktop apps where the codebase is already there and a rewrite isn't justified. We migrate incrementally, QML screens inside Widgets apps via QQuickWidget.
Yes. Module by module, one deprecated API at a time. The app stays deployable the entire way through. Most Qt 4-to-6 migrations run 10-14 weeks depending on codebase size.
Almost certainly. Qt runs on Linux, RTOS, and bare metal. Send us the SoC, GPU, display resolution, and input method, and we'll tell you on the first call exactly what it takes to get Qt rendering properly on it.
Both. We build production applications and we train in-house teams to maintain and extend them — architecture patterns, QML best practices, and the C++/QML boundary that most teams get wrong.
Yes. The engineers who write the RFC ship the code. No handoff mid-engagement, no account manager in between.
Yes. qmake, CMake, Conan, or fully custom — we adapt to what's there and flag anything, like a qmake-to-CMake migration, that genuinely needs to change.
