WhiteBox logo

WhiteBox is a software tool for showing you how your code behaves as you write it.

Humans are not good at simulating code in their head. Let the computer do what it does best.

Why bother?

Faster iteration

Seeing what functions will do lets you quickly adjust when you're not quite happy with what you see.

More iterations tend to lead to a higher-quality product.

Fewer errors

Notice basic runtime errors before you compile-and-run.

Spend less time in the debugger because you've already caught many bugs early on.

Improved understanding

Multiple representations of your running functions each show useful information that you don't (or can't) get from statically looking at the linearly written code.

Supported Languages & Platforms

WhiteBox is initially being developed for C and C-style C++ on Windows with plans to expand to other compiled languages and other platforms.
