  • BrainBash

    A heavily optimizing Brain**** interpreter written in Bash!

    It's an interesting/challenging exercise to work through implementing some basic functions in BF, ie thinking only in loops.

    I implemented an optimizing interpreter in Bash[1] on a plane ride, and it's still one of my favorite pet projects.


  • BF-JIT

    BrainFuck interpreter and optimizing JIT compiler

  • CodiumAI

    TestGPT | Generating meaningful tests for busy devs. Get non-trivial tests (and trivial, too!) suggested right inside your IDE, so you can code smart, create more value, and stay confident when you push.

  • bf

    Fast brainfuck interpreter in C (by siraben)

    Brainfuck makes it very easy to benchmark various optimizations that you can do to its interpreter.[0] Rendering a Mandelbrot set goes from 28.57 to 6.49 seconds with basic preprocessing!


  • quine-relay

    An uroboros program with 100+ programming languages

    Quine relay [1] is to this day the most "I will never understand this" brainfuck project I have ever seen.
