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
