// WHAT IT DOES

Hex puts 21 developer utilities in your pocket — the tools you reach for daily but shouldn't need a laptop to use. Format JSON, decode JWTs, generate UUIDs, test regex, convert timestamps, check diffs, hash strings, and more.

Everything runs on-device. No network, no accounts, no subscriptions. Clipboard auto-detection suggests the right tool when you copy something. Deep links let you jump straight to any tool via hex://json URLs.
