The RAD Studio IDE is used by developers worldwide to build all kinds of applications, and has an open API for expanding its capabilities. Develop and expand the IDE with your own components and IDE plug ins, or why not sell them to others!

Extend the IDE!

RAD Studio has a powerful API allowing you to extend or modify the IDE’s behavior. Create a package or DLL plugin that adds new tool windows, draws in the code editor, provides code completion, adds new project types, file types and highlighting, hooks into high-level and low-level events, tracks processes, and threads while debugging, and more.

There is a rich ecosystem of both open and closed source add-ons.

Build and Design With Your Own Controls

Build and Design With Your Own Controls

Want to write a new button? A new tree control? Tweak an existing one? You can easily write your own visual control or non-visual component, and have it as well integrated into the form designer as any control we ship with.

Used to something like MFC? Our frameworks are designed to be extended and give you as much IDE integration and design power as the ones we write. Create a native Windows control using the VCL framework. Create a cross-platform control, even one that wraps an inbuilt native control, with support for styles and more, using the FMX framework. Both have advanced properties, methods and events and full visual preview when designing a form in the IDE.
