Flowlab vs Smile Game Builder

Flowlab is a browser-based platform for making 2D games with visual, node-based behavior logic instead of written code. Its editor includes sprite editing, animation, physics, sound tools, shader effects, and visual debugging. Games run as HTML5 in a browser and receive hosted pages that can be shared or embedded on other sites. Paid plans can export games for iOS, Android, Windows, and Mac through Flowlab's build service. The Free plan costs nothing and permits three games, five levels per game, and 50 game objects, with no exports. Classroom connections include Clever SSO and roster import, Google Classroom SSO and course import, and LTI for Canvas, Blackboard, and Moodle. Teachers can create student accounts without email addresses and set school-level visibility and community controls. Online multiplayer is limited to browser games. The platform is listed for Android, iOS, macOS, web, and Windows.
