Code in Forth

An in-browser CodeMirror studio with a Forth syntax mode. Compile and run instantly — no toolchain to install.

A real VM at 60 fps

A sandboxed WASM bytecode VM with an honest per-machine cycle budget — no FFI, no fetch, no async.

Full studio suite

Sprite editors, a tracker for music and sound effects, sample import, and a cart-byte inspector.
