Hey Product Hunt community! 👋

I'm the maker behind DevArmory (https://devarmory.org), and I’m excited to share it with you all today!

💡 Why I Built This

Like most developers, I find myself needing quick utilities every single day: formatting an unreadable JSON payload, diffing two code snippets, converting a cURL command into Fetch or Python, or inspecting an expired JWT.

The hidden problem? Many random online formatters quietly transmit whatever you paste back to remote servers. If you're dealing with customer PII, internal database SQL queries, or API bearer tokens, that's a serious security and compliance risk.

I wanted a fast, beautiful, and completely private toolset that developers can use with 100% confidence.

🛡️ What Makes DevArmory Different:

- 100% Client-Side Privacy: Every single utility runs purely in your local browser memory using modern Web APIs. If you pop open your DevTools Network tab while formatting or decoding, you will see zero outbound requests. Your code never leaves your computer.

- ⌘K Command Palette: Hit `⌘K` (or `Ctrl+K`) anywhere to search and launch any tool instantly with keyboard shortcuts—just like Raycast or Spotlight.

- Offline PWA: Install it directly to your dock or desktop. Once cached, all 15 utilities work completely offline—perfect for flights or trains.

- Viral Team Sharing: Click "Share Diff" or "Share Link" to generate a compressed client-side URL that lets teammates view your exact comparison or payload with zero server database storage.

- 15 Built-in Everyday Utilities:

- JSON Formatter & Syntax Validator

- Visual Side-by-Side Code Diff Checker

- cURL to Code Converter (Python, Fetch, Go, Axios)

- SQL Beautifier & Query Formatter

- Mock Data Generator (Custom schemas & 1-click JSON export)

- JWT Token Inspector & Expiration Decoder

- Color Studio & WCAG 2.1 Contrast Auditor

- RegEx Sandbox, Unix Epoch Converter, Cron Explainer, and more.

- 100% Free Forever: No subscriptions, no feature gates, and no mandatory account creation.

🔮 What’s Next:

Based on early developer feedback, I'm already working on adding a JSON-to-TypeScript type generator and a Base64 image previewer next.

I’d love your honest feedback, critique, and feature requests:

What everyday developer utility would you like to see added to the armory next?

Thank you for your support! ⚔️
