DevGantry: Dev Tools Offline
JSON, JWT, Regex, Base64, Hash
$24.99
New in 1.1.0:
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.

Pay once. Work offline. Keep your data yours.
Version 1.1.0 adds three new tools, a live device monitor, and a faster app all round.
NEW TOOLS
• Network Tools — DNS lookup, HTTP(S) inspector, TCP port scan, WHOIS/RDAP, and offline local-network info, all in one place.
• AI Prompts — save and search your AI prompts, synced across your devices with iCloud.
• AI Prompt Creator — build a prompt section by section (task context, background documents, rules, examples) and export it as XML, Markdown, or plain text.
DEVICE MONITOR
• Device Info gains a Monitor mode with live CPU, memory, and network graphs — and you can save a snapshot to history.
IMPROVEMENTS
• Image tools can now pick from the Photo Library on iPhone and iPad, alongside Files.
• Brackets and quotes auto-close as you type in the code editors, with skip-over and pair-delete.
• JWT segments and regex matches are now color-coded, so structure is easier to read at a glance.
• HTML Preview opens .html files from the file picker or by drag-and-drop.
• Color Converter carries alpha through, so transparency survives the round trip.
• History loads the newest 200 entries with a Show More button, so a long history opens instantly.
• Faster launch, cached tool search, and debounced text tools across the app.
FIXES
• Clearing History no longer freezes the app — it runs in the background and the sheet stays responsive.
• Device Info's Monitor no longer stalls when you open the tab or come back to it.
• Label and value rows show their full content on iPhone instead of truncating.
