OpenXTalk or OXT are a pair of interlinked cross-platform rapid application development runtime systems (OXT and OXT Lite) inspired by HyperCard. They feature the xTalk Script (formerly MetaTalk, Transcript) programming language which belongs to the family of xTalk scripting languages like HyperCard's HyperTalk.
They are built on the LiveCode Community IDE that was dropped by LiveCode (company) in 2021 with a view to make sure that a Free Open Source xTalk language remains available for educators and hobbyists moving forward, as LiveCode only provide a commercial version that is available at a price point out of the reach of many educators and hobbyists.
OpenXTalk runs on MacOS, Windows 95 through Windows 10, Raspberry Pi and Linux.
