Built memscope - a real-time memory profiler for Node.js + browser. Zero config, live dashboard, 605 downloads in its first few months

Hey folks, I just published memscope - a real-time memory profiler for Node.js and browser apps that requires zero setup. It streams your backend heap (and browser JS heap) over WebSocket, sampled every 500ms, right to a local dashboard at localhost:3333 . GC dips, spikes, growth patterns — all visible at a glance. One command to start: npx memscope run node app.js Full-stack mode (backend + browser together): memscope run --both npm run dev What it tracks: Node.js heap, RSS, external memory Browser JS heap (Chromium-based) GC behavior and spikes Backend vs frontend separated on the same dashboard Why I built it: Memory bugs are painful — silent leaks, unpredictable spikes, heap snapshots that are a nightmare to read. I wanted one command that just works, with no cloud, no accounts, no data leaving your machine. It's hit 605 downloads so far and I'm actively building it out. npm: npm install -g memscope submitted by /u/monkie_momo [link] [comments]
