클라우드 기반 JSON 및 XML 포맷터 사용을 중단한 이유 (그리고 대신 구축한 것)

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?

1. Zero Latency: No waiting for network requests.
2. Infinite File Sizes: Our XML Viewer & Formatter handles massive files without crashing because it doesn’t need to POST the data to a backend.
3. Absolute Privacy: Unplug your internet after loading the page, and the tools still work!

I built this for the community. Try it out and let me know your thoughts!

(If you have 10 seconds, test the XML formatter with a huge file and let me know if it lags for you!)
