Offline-first developer utilities in one desktop app
A DevToys-style desktop app for the small jobs developers do all day. Most of its 20 tools work without a network: JSON, XML and SQL formatters, JSON and text diff, JSON ↔ YAML, Base64, URL, hashes, JWT decoding, UUIDs, timestamps and number bases. A few online ones (DNS lookup, WHOIS, IP info, currency, npm versions) use free, keyless APIs. Dense, keyboard-driven, with a command palette.
