Several Pascal compilers and interpreters are available for general use:

* [[Delphi (software)|Delphi]] is Embarcadero's (formerly Borland/CodeGear) flagship [[rapid application development]] (RAD) product. It uses the Object Pascal language (termed 'Delphi' by Borland), descended from Pascal, to create applications for [[Microsoft Windows|Windows]], [[macOS]], [[iOS]], and [[Android (operating system)|Android]]. The [[.NET]] support that existed from D8 through D2005, D2006, and D2007 has been terminated, and replaced by a new language (Prism, which is rebranded Oxygene, see below) that is not fully backward compatible. In recent years [[Unicode]] support and [[Generic programming|generics]] were [[Generic programming#In Delphi|added]] (D2009, D2010, Delphi XE).

* [[Free Pascal]] is a [[Cross-platform software|cross-platform]] compiler written in [[Object Pascal]] (and is [[Self-hosting (compilers)|self-hosting]]). It is aimed at providing a convenient and powerful compiler, both able to compile legacy applications and to be the means to develop new ones. It is distributed under the [[GNU General Public License]] (GNU GPL), while packages and runtime [[Library (computing)|library]] come under a modified [[GNU Lesser General Public License]] (GNU LGPL). In addition to compatibility modes for [[Turbo Pascal]], Delphi, and Mac Pascal, it has its own procedural and object-oriented syntax modes with support for extended features such as [[operator overloading]]. It supports many platforms and operating systems. Current versions also feature an ISO mode.

* [[Turbo51]] is a free Pascal compiler for the [[Intel 8051]] family of microcontrollers, with [[Turbo Pascal]] 7 syntax.

* [[Oxygene (programming language)|Oxygene]] (formerly named ''Chrome'') is an Object Pascal compiler for the [[.NET Framework|.NET]] and [[Mono (software)|Mono]] platforms. It was created and is sold by [[RemObjects Software]], and sold for a while by Embarcadero as the backend compiler of [[Delphi Prism|Prism]].

* [[Kylix (software)|Kylix]] was a descendant of [[Delphi (software)|Delphi]], with support for the [[Linux]] operating system and an improved object library. It is no longer supported. Compiler and IDE are available now for non-commercial use.

* [[GNU Pascal]] Compiler (GPC) is the Pascal compiler of the [[GNU Compiler Collection]] (GCC). The compiler is written in C, the runtime library mostly in Pascal. Distributed under the [[GNU General Public License]], it runs on many platforms and operating systems. It supports the ANSI/ISO standard languages and has partial Turbo Pascal dialect support. One of the more notable omissions is the absence of a fully Turbo Pascal-compatible (short)string type. Support for Borland Delphi and other language variants is quite limited. There is some support for Mac-pascal, however.
