A development tool that lets people build applications using visual drag-and-drop interfaces and minimal hand-coding. Like building with LEGO blocks instead of carving each piece from raw wood — you snap pre-built components together to create something functional.
A bank's operations team uses Microsoft Power Apps to build an internal loan approval workflow in a week, complete with forms, approvals, and database storage — a project that would have taken the IT department months to code from scratch.
All four are low-code tools for building business apps with visual designers, data connectors, and workflow automation. Power Apps and AppSheet are strong for rapid internal apps and integrations; Oracle APEX is tightly integrated with Oracle Database; AWS App Studio focuses on quickly building internal business apps on AWS with managed integrations.
