About st-forth

A Forth programming language interpreter that runs entirely in your browser via WebAssembly.

st-forth features a 4-tier vocabulary system that demonstrates how Forth builds itself from a minimal kernel of ~35 primitives into a full-featured language — all through Forth code defining new words.

Features

• Split REPL + editor interface with live stack display
• 4-tier vocabulary: Kernel, Core, Standard, Full
• Save and share programs via URL
• Example gallery
• Terminal REPL also available (st-forth CLI)
