A low-code development platform (LCDP) provides a development environment used to create application software, generally through a graphical user interface (as opposed to only writing code, though some coding is possible and may be required). A low-coded platform may produce entirely operational applications, or require additional coding for ...
A web application (or web app) is application software that is created with web technologies and runs via a web browser. [1] [2] Web applications emerged during the late 1990s and allowed for the server to dynamically build a response to the request, in contrast to static web pages.
