JSONLab

I built this because I kept running into the same frustration every day - opening JSON tools online and immediately getting hit with slow loading, ads, trackers, and unnecessary backend calls. Simple tasks like formatting JSON or converting XML would lag, reload, or send my data to someone else’s server. So I wanted a different kind of tool: Instant (no loading) Private (runs 100% in the browser) Ad-free and distraction-free Fast even on low-end devices No backend, no tracking, no storage The goal was simple: Make the fastest and most private JSON tools on the internet.
