Brainfuck Interpreter Online
Brainfuck is a minimalist esoteric programming language with only 8 commands. Despite its simplicity, it is Turing-complete. This interpreter runs programs client-side with a 30,000-cell byte array (values 0–255) and a 500,000-step safety limit to prevent infinite loops. Non-command characters are treated as comments.
Private & free — this tool runs entirely in your browser.
