Why I stopped using cloud-based JSON and XML formatters (And what I built instead)

As developers, we constantly copy-paste data into online formatters, decoders, and tools. But have you ever stopped to think where that data goes? If you're pasting an API response with PII (Personally Identifiable Information) into a random cloud formatter, you might be violating compliance rules.

That’s why I created FreeClientToolbox. It’s a suite of over 180 utilities where all processing happens directly in the browser via JavaScript and WebAssembly.

Why Client-Side?

Zero Latency: No waiting for network requests.

Infinite File Sizes: Our XML Viewer & Formatter handles massive files without crashing because it doesn't need to POST the data to a backend.
