I’ve been working on MemViz, a tool to help inspect and visualize memory in C++ programs. It’s aimed at developers, students, and systems engineers who want a simple way to look under the hood without firing up a heavyweight debugger.
What it does:
Inspect object layouts, padding, and alignment.
Explore vtables and runtime dispatch.
Track allocations and report possible leaks.
Hex-dump mapped memory regions (mmap / CreateFileMapping).
Uses modern C++20 features like std::bit_cast for safe reinterpretation.
Why I built it: I found existing debuggers very powerful but often overwhelming for quick introspection. I wanted a lightweight, modern, and approachable tool to learn about object memory layouts, teach others about the C++ object model, and do simple leak/hex inspections.
Try it out:
Repo: https://github.com/LA-10/MemViz
It’s header-only in parts, with examples and test files you can build right away.
No signups, no barriers — just clone and run.
Feedback I’d love:
Is this useful in your workflow or teaching?
What features would you want for a simple memory visualization tool?
Where does it overlap or complement tools like ASan/Valgrind?
I’m around to discuss, answer questions, and hear any suggestions. It's very simple currently.
Thanks!
