Delphi is an (IDE) for of desktop,,, and software, developed. It is also an language. Delphi's compilers use their own dialect of and generate for, ( only),, and ( only). Since 2016, there have been new releases of Delphi every six months, with new platforms being added approximately every second release. Delphi includes a code editor, a visual designer, an integrated debugger, a component, and support for third-party. The code editor features (), Error Insight (real-time error-checking),.

The visual forms designer has traditionally used (VCL) for native Windows development, but the (FMX) platform was later added for cross-platform development. Database support in Delphi is very strong. A Delphi project of a million lines to compile in a few seconds – one benchmark [ ] gave 170,000 lines per second. Delphi was originally developed by as a tool for Windows as the successor of.

Delphi added full to the existing language, and since then the language has grown to support generics and, and native (COM) support. In 2006, Borland’s developer tools section was transferred from Borland to a wholly owned subsidiary known as, which was sold to in 2008. In 2015, Embarcadero was purchased by, but the Embarcadero mark was retained for the developer tools division. Delphi and its counterpart,, are interoperable. They share many core components, notably the IDE, VCL, and much of the. In addition, they can be used jointly in a project.

For example, C++Builder 6 and later can consume Delphi source code and C++ in one project, while packages compiled with C++Builder can be used from within Delphi. In 2007, the products were released jointly as, a shared host for Delphi and C++Builder, which can be purchased with either or both.

[ ] Delphi uses the -based programming language called introduced by Borland. It supports native.

Its visual designer has traditionally used (VCL) for RAD. To better support development for Microsoft Windows and interoperate with code developed with other software development tools, Delphi supports independent interfaces of (COM) with class implementations, and support for many third-party components.

Implementations can be delegated to fields or properties of classes. Message handlers are implemented by tagging a method of a class with the integer constant of the message to handle. Connectivity is extensively supported through the many VCL database-aware and database access components.

Later versions have included upgraded and enhanced runtime library routines provided by the community group, established in 2003. Characteristics [ ] Delphi is a, intended to be easy to use and originally based on the earlier Object Pascal language. Was originally developed as a general-purpose language 'suitable for expressing the fundamental constructs known at the time in a concise and logical way', and 'its implementation was to be efficient and competitive with existing FORTRAN compilers' but without low-level programming facilities or access to hardware. Turbo Pascal and its descendants, including Delphi, support access to hardware and low-level programming, with the facility to incorporate code written in and other languages. Delphi's features only class- and interface-based. Metaclasses are first class objects. Objects are actually references to the objects (as in ), which Delphi implicitly de-references, so there is usually no need to manually allocate memory for pointers to objects or use similar techniques that some other languages need.
