fuite is a CLI tool that finds memory leaks in web apps by launching Chrome via Puppeteer, running scenarios (like clicking links and pressing back) repeatedly, and analyzing heap snapshots for leaked objects, event listeners, DOM nodes, and collections. It outputs findings to stdout or a detailed JSON file.

Use cases

• find memory leaks in a single-page application
• detect leaked event listeners and DOM nodes in a web app
• check if client-side routing leaks memory on navigation
• run automated memory leak detection in CI
• analyze heap snapshots for growing collections like Maps and Sets

When to choose

• you maintain a client-rendered SPA and want automated leak detection
• you want a quick npx-runnable tool to catch leaks from navigation scenarios
• you need JSON output with details like the source line of a leaked listener

When to avoid

• you need memory profiling of Node.js server code rather than browser apps
• you require a GUI-based heap analysis workflow like Chrome DevTools
• your app is server-rendered with no internal links to click and no custom scenario available
