Rapid Development, Modern Workflow

Modern Design

Reflex introduces a first-class Object model with a dynamic property system, purpose-built for rapid iteration, live systems, and modern UI workflows.

Properties are data-driven, introspectable, and serializable by default, and integrate seamlessly with structured formats like JSON. This unlocks the speed and flexibility developers expect from web and dynamic languages - live UI updates, declarative configuration, and effortless composition - yet with native performance, fast compile times and tiny binaries.

Powerful and Flexible

Reflex is carefully designed as a modular stack, with the higher levels bringing all the benefits of modern, rapid development approaches seen in dynamic languages and web-tech, but always allowing you to dive deeper when finer control is needed.

No More
Compromise

Performance Matters

Granular Control.
Ultimate Performance.

You develop in C++ because you care about performance and control. So do we.

Reflex is the C++ development framework that outperforms web tech for UI. A fully native unified stack, dependency free, Reflex is engineered for uncompromised performance and combines modern development paradigms with true low-level control.

Built to deliver fluid, user-focused apps, Reflex features a powerful GPU-accelerated UI system, including responsive layout, stylesheet-driven design, and live editing for fast iteration.

"Most frameworks feel like a long slog back to the bare metal. With Reflex, it's always within reach."

Modern. Lightweight. Lightning-fast. Built for developers who refuse to compromise.

No Webviews Needed

Reflex features a complete GPU-powered UI, with powerful layout model, stylesheets and hot reloading. Everything good about HTML/CSS/JS webviews without the legacy, bloat and having to manage two sets of state.

Instant Updates

Hot reloading of stylesheets. No need to recompile to view changes and iterate. See your UI updates instantly while maintaining native C++ performance.

Cross-Platform Apps

Write once, deploy everywhere. Build native applications for Windows, macOS, iOS, and Android from a single codebase without compromising on platform-specific performance.

Native Performance

Zero runtime overhead. Your UI code compiles to native machine code, delivering the raw performance that C++ developers expect. No interpreters, no virtual machines.

Pro-Audio and Beyond

With built-in low-latency audio support and first-class plugin integration, Reflex is a natural choice for pro-audio software development. Beyond audio, Reflex is suited to any cross-platform project requiring real-time responsiveness, high-performance execution, and rich, GPU-accelerated user interfaces.
