What are some edge cases for Mock Generator?

Generating more than 100,000 rows might slow down the browser.

Is this Mock Generator safe for sensitive data & credentials?

Yes, 100%. All processing runs client-side in your local browser memory. No text, tokens, payloads, or logs are ever transmitted to any remote server or analytics engine.

Can I use Mock Generator offline without internet?

Yes. Because this tool runs strictly on client-side JavaScript with zero external API calls, once the web application is loaded in your browser it will continue working offline.

How does URL state sharing work?

When you click Share Payload, your state is encoded directly into a URL hash fragment (#data=...) without storing anything on a database server.
