DevGantry: Dev Tools Offline
JSON, JWT, Regex, Base64, Hash
$24.99 · In‑App Purchases
Network Tools (DNS, HTTP, port scan, WHOIS), an iCloud-synced AI prompt library, a guided prompt composer, and live CPU/memory graphs.
107 tools, one price.
100+ developer tools in one native app for Mac, iPhone, and iPad. Format JSON, decode a JWT, test a regex, hash a string — offline, on your device.
DevGantry is a toolbox, not a website. No browser tabs, no upload spinners, no ads next to your API keys. Everything runs locally unless a tool clearly says otherwise.

YOUR WORK, EVERYWHERE
Save any result to history and it syncs across Mac, iPhone, and iPad through your own iCloud account — no DevGantry account, no third-party server. Pin the keepers into a permanent snippet library.
PRIVATE BY DESIGN
No accounts, no analytics, no crash reporting, no ads, no trackers.
Only five features ever reach the network — CEP lookup, What's My IP, HTML Preview, Link Preview, and Network Tools, which contacts only the hosts you type in. Each one says so in the app. Everything else is fully offline.
Secrets stay out of your history: TOTP keys, encryption keys, and passwords are never recorded.
TRULY NATIVE
Built entirely in SwiftUI with SF Symbols — quick to launch and at home on macOS, iOS, and iPadOS.
Available in English, Português (BR), Español, Français, and Deutsch.
