Qt1t

Qt1t is a cross-platform application framework and graphical user interface toolkit designed to enable rapid development of desktop and embedded software. It provides a modular core, a declarative UI language, and a platform abstraction layer that targets both desktop and resource-constrained devices. The project emphasizes small binary size, predictable memory usage, and a clean API suitable for education, prototyping, and embedded deployments. It is described as open source and community‑driven, with governance by a lightweight maintainers’ council.

Qt1t was introduced in 2020 by Q1nix Labs as an evolution of ideas within the Qt ecosystem, intended to explore modularity, permissive licensing, and alternative rendering stacks. Since its inception, the project has accepted contributions from individuals and groups in the open‑source community, produced several major releases, and established a growing ecosystem of plugins and bindings.

The architecture comprises a minimal core event loop, a signals‑and‑slots style communication mechanism, and a plugin system that supplies rendering backends (OpenGL, Vulkan, software renderer), input handling, networking, and multimedia services. It ships with a declarative UI language called Q1ML that binds UI elements to data models in a type‑safe manner, alongside a comprehensive set of standard widgets and layout managers. Rendering is supported across Windows, Linux, macOS, Android, and iOS, with experimental builds for some RTOS targets.

Qt1t is released under a permissive open‑source license. Development is community‑oriented, with documentation, tutorials, and example projects available through the project’s website and mirrors. See also Qt, GUI toolkit, cross‑platform development, embedded systems.
