Brisk is a new cross-platform C++ GUI framework designed to support declarative and reactive programming. It aims to enhance the development experience with an efficient data binding strategy, positioning itself as a modern alternative to established frameworks like Qt and wxWidgets. Key discussions in user comments highlight concerns about memory management due to naked 'new' operators and the need for better support regarding keybindings. Despite this, commenters express curiosity about Brisk's innovative approach to data binding and question how it differentiates itself from existing frameworks. There are also concerns regarding licensing, as Brisk is not open-source under usual permissive licenses, potentially limiting its usability for some developers.
