System

PaskalCPP is a systems language by Jarrod Davis: Pascal/Oberon-style syntax that transpiles to C++23 and builds with a bundled Zig/Clang toolchain. Mix PaskalCPP and C++ in one file, no bindings. Includes a Delphi-built compiler and language server, an Electron/Monaco editor, and diagnostics mapped to your source. Native Windows and Linux binaries.

Delphi VCL bridge for exposing forms, controls, diagnostics, and tools through the Model Context Protocol.

Other

Spintax Studio

Spintax Studio is a native Windows editor for spintax templates: two panes, your template on the left, its live render on the right. Preview and the valid/invalid verdict come from the real spintax engine inside the application, not from a second parser. Diagnostics carry line and column positions and link to the built-in help; panels list variable definitions, references, session values and #include targets with their resolution status. Generate variants locally, reproduce them with a seed, and export as plain text, an XLSX workbook, or one file per variant. Offline by default: no account, no telemetry, no Node.js, PHP or Python runtime — one self-contained executable. Optional AI drafting is off until you turn it on and talks only to the endpoint you configure, with your own key when it needs one. Interface and built-in help in 14 languages. Free and open source, GPL-3.0-or-later. The SPINTAX language and its engine family are documented at spintax.net.
