Demand for C++ Compiler Visualization Tool

Updated 10/9/2026, 22:05:33

Problem

Developers want to visually understand the compiler's internal reasoning, especially for complex features like lambda captures, and desire an online tool that can compare outputs across compilers for better comprehension and debugging.

Ooo I love these things. I wrote a C++ -> Clang -> JS transpiler so I could show value change states on top of the C++ source code in html and allow people to step through the whole state change. They can also vary the input and see the values change cause the JS layer could recompute the values - which is why I bothered with the transpiling - otherwise I could have just output the state changes and parsed them as CSV for the steps. Fun project!

Definitely trying this out. I've always had the problem of "but is the compiler thinking?" with C++ in particular.

I wish the readme example showed a lambda capture. Now that's where compiler magic REALLY shows up.
