Lazarus is a free and open-source Integrated Development Environment (IDE) specifically tailored for Rapid Application Development (RAD). It is designed to be Delphi-compatible, offering a seamless transition for developers familiar with Delphi. Lazarus supports cross-platform development, enabling the creation of applications that can run on various operating systems. With a visual form designer and an array of components, Lazarus simplifies the process of building complex graphical user interfaces.

Features of Lazarus Key:

  • Cross-Platform Development: Lazarus enables developers to create applications that seamlessly run on Windows, macOS, Linux, and other platforms, including Raspberry Pi.
  • Delphi Compatibility: Lazarus is designed to be compatible with Delphi, providing a familiar environment for developers acquainted with Delphi's Object Pascal language.
  • Visual Form Designer: The IDE features a powerful drag-and-drop form designer, streamlining the creation of intricate graphical user interfaces.
  • Rapid Application Development (RAD): Lazarus facilitates rapid development with an integrated environment, making it suitable for creating a diverse range of applications.
  • Flexible Licensing: LGPL licensed libraries allow developers to create applications under any desired license, including commercial closed-source projects.
  • GPL Licensed IDE: The Lazarus IDE itself is distributed under the GPL license, providing an open-source foundation for development.
  • Ease of Use:
