SelfCopyCode

SelfCopyCode is an interactive web-based editor that allows you to write and execute code in BFF (Brainfuck++), and visually explore how the output is generated.
BFF was introduced in the paper Computational Life: How Well-formed, Self-replicating Programs Emerge from Simple Interaction, as a Brainfuck extension to study the emergence of self-replicating programs.

This tool provides a hands-on way to understand and visualize how a minimal self-replicator operates at the instruction level.

Features

• Write and run BFF code in your browser
• Step-by-step visualization of code execution
• Displays memory cells, instruction pointer, and output
• Demonstrates self-replication in action
