Frequently asked questions
Is JS Dependency Analyzer free to use?
Yes. JS Dependency Analyzer is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does JS Dependency Analyzer upload your file to a server?
No. JS Dependency Analyzer processes your file inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.
Is there a limit on how much input I can use?
JS Dependency Analyzer handles inputs into the megabytes without trouble; the only real limit is how much your browser tab can hold in memory.
Do I need to install anything to use JS Dependency Analyzer?
No installation is needed. JS Dependency Analyzer runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use JS Dependency Analyzer on a phone or tablet?
Yes. The JS Dependency Analyzer interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.
What happens to your file when I close the tab?
It is discarded. JS Dependency Analyzer keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
