Simple memory profiling tool written for the NGINX Javascript Module (njs)

A micro-library of stream components for building custom JSON and JSONC processing pipelines with a minimal memory footprint — parse, filter, and transform JSON far larger than available memory with a SAX-inspired token API, on Node.js or Web Streams.

Memory and event loop testing for Node.js — heap monitoring, event loop delay and utilization tracking, object lifecycle verification, stream buffer assertions, and comparative profiling

Middy AWS Lambda CPU profiler middleware

Continuous CPU profiling for Bun (JavaScriptCore) via Pyroscope/Grafana ingest — zero native dependencies

Live GPU memory profiler for WebGPU. Patches GPUDevice once and gives you exact byte-level snapshots of every buffer and texture, plus an optional React HUD overlay.

memlab is a framework that analyzes memory and finds memory leaks in JavaScript applications.

one rAF to rule them all

Scan your React app for renders

Run a promise (perhaps with p-queue) generating a profiler json suitable to be consumed inside Chrome or Edge devtools to be analyzed

pyroscope nodejs package

This is lightweight memory stream module for node.js.

This is the implementation of the Profiler for iOS app. It uses [py-ios-device](https://github.com/YueChen-C/py-ios-device) to poll CPU, RAM and FPS data in real time.

In-memory state adapter for Chat SDK — zero-dependency subscriptions, locks, and cache for local development and tests

NestJS web profiler module inspired by Symfony's Web Profiler

MongoDB Server for testing (core package, without autodownload). The server will allow you to connect your favourite ODM or client library to the MongoDB Server and run parallel integration tests isolated from each other.

A performance profiler panel addon for Storybook — real-time FPS, INP, CLS, memory and more. Works with all Storybook frameworks.
