Your code looks fine until it reaches your users. Visurx shows you exactly what your code does — and where it breaks — before it ever ships.
N+1 loop pattern matched inside runtime callstack

Process Pipeline
Point Visurx at your repository. No agent to install, no SDK to wrap your code around, no configuration files to write.
Choose a single function, a section of code, or your entire project. Visurx runs it in a completely isolated environment — safely, privately, separately from production.
Get a clear, visual picture of how your code behaves: where it's slow, what it's using, where it might fail. Before anyone else sees it.
Engine Scope
See per-function timing down to the millisecond, so you know exactly which call in the stack ate the 340ms — not just that the request was slow.
Watch heap size before and after each run. Catch a leaking closure or unbounded array while it's still megabytes, not gigabytes.
Measure event loop lag in milliseconds and see which awaited call is blocking the next tick, before users feel the delay.
Static analysis flags N+1 query patterns and nested loops calling the database, caught by reading your code — no test run required.
A visual graph of every file, function, and import in your project, so you can trace what actually calls what before you refactor.
Every run happens in its own sandbox with its own process and memory space — nothing you test here ever touches production.
Development Cycle
Run any Node.js project. Visurx captures CPU usage, memory behavior, async timing, and where time is actually spent — before you ship.
Go deeper than the runtime. Visurx will observe what your code actually does at the operating system level — the full picture, nothing hidden.
See exactly which database queries are slow, which API calls are wasteful, and where your application loses time talking to external services.
Your UI, profiled. Load times, rendering bottlenecks, interaction delays — measured before real users encounter them.
Python, Go, and more. Same depth of insight, same pre-production safety net — across your entire stack, not just Node.js.
Not just what broke — why it broke and exactly how to fix it. Powered by everything Visurx has learned about your codebase over time.
Join the beta. Debug your Node.js code before it ships. No credit card, no production access, no setup.
