'''Curl''' is a [[Reflective programming|reflective]] [[Object-oriented programming|object-oriented]] [[programming language]] for interactive [[web application]]s, whose goal is to provide a smoother transition between [[content format]]ting and [[computer programming]]. It makes it possible to embed complex objects in simple documents without needing to switch between programming languages or development platforms. The Curl implementation initially consisted of an [[Interpreter (computing)|interpreter]] only; a [[compiler]] was added later.

Curl combines text [[Markup language|markup]] (as in HyperText Markup Language ([[HTML]])), scripting (as in [[JavaScript]]), and heavy-duty computing (as in [[Java (programming language)|Java]], [[C Sharp (programming language)|C#]], or [[C++]]) within one unified framework. It is used in a range of internal enterprise, [[business-to-business]] (B2B), and [[business-to-consumer]] (B2C) applications.

Curl programs may be compiled into Curl applets, that are viewed using the Curl RTE, a [[runtime environment]] with a [[Plug-in (computing)|plugin]] for [[web browser]]s. Currently, it is supported on [[Microsoft Windows]]. [[Linux]], and [[macOS]] was dropped on March 25, 2019 (starting with version 8.0.10).<ref>{{cite web |url=https://www.curl.com/release/2019/20190325_1.html |publisher=SCSK Corporation |access-date=2020-04-01 |archive-url=https://web.archive.org/web/20190513081808/https://www.curl.com/release/2019/20190325_1.html |archive-date=2019-05-13 |url-status=live |title=Changes to Supported Operating Systems of Curl RTE Products }}</ref> Curl supports [https://web.archive.org/web/20110708213458/http://developers.curl.com/userdocs/docs/en/dguide/detached.html "detached applets"], which is a web deployed applet which runs on the user's desktop independent of a browser window much as in [[Microsoft Silverlight]] 3 and [[Adobe AIR]].
