Modules are designed to speed up development and minimize the time required to implement common tasks. There are plenty of modules, designed by the AppMaster.io team and many more are coming. Modules can include predefined data models, custom business logic, custom code, preconfigured endpoints, UI components, integrations, and more.
Recently we simplified the modules hierarchy and dropped support for multiple types of modules to unify architecture. Most modules are now accessible via Business Process Editor.
