Lazarus (software)
open-in-new
<p>Lazarus is a <a href="/facts/Cross-platform_software/16zqdvNR">cross-platform</a>, <a href="/facts/Integrated_development_environment/jbEINSQf">integrated development environment</a> (IDE) for <a href="/facts/Rapid_application_development/LX6JuaE4">rapid application development</a> (RAD) using the <a href="/facts/Free_Pascal/kmGChqAg">Free Pascal</a> <a href="/facts/Compiler/WNfCDFJe">compiler</a>. Its goal is to provide an easy-to-use development environment for developing with the <a href="/facts/Object_Pascal/cuGkuISv">Object Pascal</a> language, which is as close as possible to <a href="/facts/Delphi_(software)/sUFUXQ8r">Delphi</a>. It is <a href="/facts/Free_and_open-source_software/1cHtjLCB">free and open-source software</a> with different parts released under different <a href="/facts/Software_license/7enfIqhL">software licenses</a>. </p><p>Lazarus is often used to create native-code console and <a href="/facts/Graphical_user_interface/wBlQFWDP">graphical user interface</a> (GUI) applications for <a href="/facts/Desktop_computer/edFPINdK">desktop computers</a>, <a href="/facts/Mobile_device/cNS1Rhvg">mobile devices</a>, <a href="/facts/Web_application/BLkF3BIN">web applications</a>, <a href="/facts/Web_service/qxrwqB3D">web services</a>, visual components, and function <a href="/facts/Library_(computing)/xRzL3P7q">libraries</a> for several different <a href="/facts/Operating_system/8XTuvMh2">operating system</a> <a href="/facts/Computing_platform/DmKwp5Bk">platforms</a>, including <a href="/facts/MacOS/Y93vVpTm">macOS</a>, <a href="/facts/Linux/9FvCKSTq">Linux</a>, and <a href="/facts/Windows/bwhAhuSL">Windows</a>. </p><p>A project created by using Lazarus on one platform can be compiled on any other one which <a href="/facts/Free_Pascal/kmGChqAg">Free Pascal</a> compiler supports. For desktop applications, one <a href="/facts/Source_code/o9J6Jv23">source code</a> can target <a href="/facts/MacOS/Y93vVpTm">macOS</a>, <a href="/facts/Linux/9FvCKSTq">Linux</a>, and <a href="/facts/Windows/bwhAhuSL">Windows</a>, with little or no modification. For example, the Lazarus IDE is created from one code base and available on all major platforms including <a href="/facts/Raspberry_Pi/Ie6Lx9n5">Raspberry Pi</a>. </p>
