You aren’t a computer

It takes so long to get feedback from conventional tools that you resort to mentally debugging your code.

Unfortunately humans are bad at simulating code in their head so even experienced programmers frequently make errors.

WhiteBox makes it fast and frictionless to see how your code actually runs, so you can keep your mental model up-to-date.

Testimonials

“WhiteBox delivers hope for a future where better software is written, and coding isn’t such a mess. Where it’s more enjoyable because you have a better understanding of the code you’re working with and don’t have to spend as much time debugging.”

“Using WhiteBox is like having a conversation with the computer.”

“With WhiteBox, you can literally just put your cursor where you want to inspect, and instantly see the state of any data that is there at that point in time.”

“WhiteBox makes it quickly apparent when the user/developer’s simplified mental model doesn’t match what the instructions are doing.”
