Why Minimal BASIC?

  • Instant feedback — run your program with one tap; errors appear in context.
  • Pure ECMA‑55 — engine validated with the NBS 200‑test suite for full standard compliance.
  • Powered by modern tech — interpreter built with ANTLR 4, fast and portable.
  • Offline & private — everything runs locally; no account, no cloud, no tracking.
