Bubble is a no-code platform that enables users to build web applications without writing traditional code.

Bubble's visual programming interface lets users design their application's interface and define its logic and workflows through a series of point-and-click actions. Key features include a visual database designer, user authentication systems, and the ability to integrate with external APIs. Bubble is particularly powerful for creating marketplaces, social networks, and other complex web applications that would typically require significant coding. While it has a steeper learning curve than traditional website builders, Bubble offers extensive capabilities for creating fully functional web applications without the need for traditional programming skills.
