Qt

Qt Group is a global software company that builds cross-platform development, design, and quality-assurance tools used across more than 70 industries and billions of devices. Its portfolio spans the Qt Framework (cross-platform C++ software libraries and APIs), the Qt Creator IDE, Qt for MCUs, Qt Design Studio, and the quality-assurance suite (Squish GUI test automation, Coco code coverage, Test Center, and Axivion static analysis). Qt does not publish a public REST/HTTP API; its "APIs" are C++/QML/Python library APIs shipped with the framework, with the official Python bindings (PySide6/PySide2) distributed on PyPI. Documentation, learning, and support are provided through doc.qt.io, the Qt Academy, and forum.qt.io.

Qt is profiled on the APIs.io network. Tagged areas include Company, Enterprise, Developer Tools, Cross-Platform, and Framework.

Qt’s developer surface includes documentation, engineering blog, support, pricing, signup flow, and 8 more developer resources.
