Frequently asked questions
Is JSON Diff really free?
Yes. JSON Diff is completely free on PureBrowser — every feature, with no account, no trial, and no credit card.
Does JSON Diff upload my data?
No. JSON Diff runs entirely inside your browser, so anything you type, paste, or open stays on your own device.
Do I need to sign up or install anything?
Neither. There is no account and nothing to download — open the page and JSON Diff is ready to use on desktop or mobile.
Does JSON Diff work offline?
Once the page has loaded, yes. All of the processing happens locally in your browser, so it keeps working without a connection.
