Lazarus
Lazarus is a free, cross-platform integrated development environment (IDE) for rapid application development using the Object Pascal programming language. It provides a visual form designer, code editor, and compiler to create native applications for Windows, macOS, Linux, and other platforms. The IDE is built on the Free Pascal Compiler (FPC) and supports the creation of desktop, console, and web applications.
Developers should learn Lazarus when they need to build cross-platform desktop applications quickly with a visual design approach, particularly for legacy systems or projects requiring Pascal compatibility. It is ideal for educational purposes, small to medium-sized business applications, and scenarios where a RAD (Rapid Application Development) tool with a low learning curve is beneficial, such as in government or niche industries that rely on Pascal-based software.
