THE CODE.
FROM ANOTHER
ANGLE.

Same rigor. Less syntax between you and your logic.

Place your functions. Connect your modules. Watch your program run. A real AST under the blocks, not black magic.

[01]

Visual. Not simplistic.

Functions, classes, lambdas, pointers and generics. The concepts stay. The representation changes.

[02]

Run. Pause. Understand.

Local simulation, breakpoints and memory inspection. No backend needed to follow your logic.

[03]

Your project stays yours.

Local workspace, versioned JSON source, standalone HTML export. The application code is on GitHub.

* Transpilation is available for a documented subset. Classes and graphical widgets are not transpiled. Captures predate the current visual direction. This site describes the current code; releases may lag behind.

03 / UNDER THE HOOD
