## What it is
A set of JavaScript libraries, tools, and visualizers from Google for instrumenting, tracing, and analyzing complex web applications. It helps developers find performance problems and build smooth 60fps web apps, with a Chrome extension for capture and rich trace visualization.

## Use cases
- find performance bottlenecks in web apps
- trace and visualize javascript execution
- debug jank to hit 60fps
- capture and replay canvas and webgl rendering
- track memory allocations per function
- remotely trace chrome for android pages

## When to choose
- you need fine-grained custom instrumentation of javascript async flows
- you want to analyze canvas/webgl rendering or heap allocations in the browser
- you need a visualizer for millions of trace events

## When to avoid
- you need actively maintained tooling - the project is largely dormant since ~2019
- you just need basic profiling - Chrome DevTools covers most needs today
- you need server-side or non-browser tracing

## Facets
- artifact type: library
- maturity: abandoned
- function: tracing, monitoring, data-visualization, developer-tools
- domain: web-development, frontend, performance, developer-tools
- platform: browser
- tags: web-performance, profiling, chrome-extension, webgl, canvas-replay, heap-tracking, javascript, nodejs
