No. Doohickey’s Dev Tools only loads on its own admin page. It adds zero scripts, styles, or markup to your public-facing site.

Do I need to be online for the tools to work?

Most tools work entirely offline once the page is loaded. The QR Code generator and Placeholder Image generator use client-side rendering. No external API calls are made.

Pro unlocks 5 additional tools (Palette Generator, Code Formatter, Diff Checker, HTML Table Generator, Test Data Generator) plus advanced features in 5 more tools. The Pro version is available separately at mosaiclifecreative.com.

Is my code/data sent anywhere?

Never. All processing happens in your browser. Nothing is transmitted to external servers.
