## What it is
spy-js is a JavaScript tracing, debugging, and profiling tool developed by JetBrains, bundled with WebStorm and IntelliJ IDEA Ultimate and available as a plugin for other JetBrains IDEs. The tool itself is not open source; this repository only holds MIT-licensed documentation and samples, and the project has been inactive since 2020.

## Use cases
- trace javascript execution across browsers and devices
- debug javascript in browsers without devtools
- profile node.js applications
- trace javascript on mobile devices via proxy
- trace https javascript traffic
- debug code running in phantomjs or karma runner

## When to choose
- you use WebStorm or IntelliJ IDEA Ultimate and need cross-browser JS tracing
- you need to trace JavaScript on devices where browser devtools are unavailable

## When to avoid
- you need an actively maintained tool (last release 2020, effectively abandoned)
- you require open-source software (the tool itself is proprietary)
- you don't use a JetBrains IDE
- you need modern browser devtools features like source maps for ES modules

## Facets
- artifact type: plugin
- maturity: abandoned
- function: tracing, monitoring, developer-tools
- domain: web-development, frontend, developer-tools
- platform: cross-platform
