Debugging memory leaks has always been one of those tasks developers dread.
Tools like Valgrind or WinDbg are powerful, but they’re either platform‑specific or too complex for quick diagnostics. I wanted something different: a tool that gives developers answers fast.
That’s the philosophy behind Mvis — a Rust‑based memory visualizer and leak detector.
Why Mvis
Mvis is built around three guiding principles:
Simplicity: One command should be enough to get useful insights.
Accessibility: Debugging shouldn’t be locked behind steep learning curves.
Cross‑platform: Whether you’re on Windows or Linux, the workflow should feel the same.
Or as I like to put it:
“One command. All platforms. No configuration hell.”
What it can do
Even in its early stage, Mvis already supports:
Process scanning: Inspect allocations of active processes.
Heap‑level analysis: See heap structures in detail.
DLL tracking: Monitor loaded libraries.
Leak detection: Identify processes with growing, unreleased allocations.
Stack tracing: Capture call stacks to pinpoint allocation sources.
Supported OS: Windows and Linux.
Quick Usage Examples
# visualize memory map
mvis scan myapp.exe -a
# detect leaks
mvis leak leaking_app.exe 10
# multi-sample leak detection
mvis leak-m myapp.exe 10 3
Outputs are clear and exportable to JSON(Scan), making analysis and visualization easy.
Example: Leak Detection
mvis leak leaking_app.exe 10
Insights
One of the first problems I encountered was:
How do I make Mvis work on both Windows and Linux?
The answer turned out to be simple: platform abstraction.
Mvis defines abstractions for memory regions and heap blocks, which means the core logic doesn’t depend on OS‑specific quirks.
Because of this design, it’s possible to extend support to other platforms in the future — as long as they implement the same abstraction layer Mvis uses..
Roadmap
Mvis is still early but functional. Here’s what’s coming next:
TUI frontend for heap analysis (lightweight by design).
Heap fragmentation visualization.
Realtime heap scanning.
macOS support.
Performance improvements.

mvis: Memory debugging for developers who just want answers Simple. Fast. Works everywhere.
Why mvis?
Existing tools are either platform-specific (Valgrind, WinDbg) or too complex for quick diagnostics. mvis gives you memory insights with a single command on any platform.
Our design philosophy is built around simplicity and accessibility because We believe memory debugging should be accessible, not a PhD requirement.
"One command. All platforms. No configuration hell."
Status
Early but functional. Core scanning and leak detection work on both platforms. See the roadmap below for what's coming.
Features
- Process Scanning: Inspect memory allocations of active processes.
- Heap-Level Analysis: Dive into heap structures for detailed debugging.
- DLL Tracking: Monitor and list all DLLs loaded by a target.
- Memory Leak Detection: Identify and monitor processes with growing, unreleased allocations.
- Stack Tracing: Capture call stacks to pinpoint allocation sources and trace execution paths. (Linux)
- Supported OS…
Feedback, contributions, and ideas are welcome. Let’s make memory debugging easier for everyone.
