I built a 100% Privacy-First Toolbox for Developers (No more pasting JWTs into random sites)

Hey everyone! 👋

As a developer, I found myself using online JSON formatters or JWT decoders every day. But I always felt a bit uneasy pasting sensitive production data or customer tokens into sites where I didn't know where the data was going.

So, I built SyntaxSnap — a 100% local-first developer workbench.

🔒 The Rule

Everything runs in your browser memory. No API calls. No databases. No tracking. Your production data, schemas, and tokens never touch a server.

⚡ What's inside?

• TypeScript/JSON to Zod: Generate schemas instantly for your Next.js/React projects.
• Secure JWT Debugger: Inspect tokens without sending them to a third party.
• Aurora Gradient & Tailwind v4 Tools: Visual tools for modern CSS.
• 100% Offline-first: Works without an internet connection once loaded.

🧩 Chrome Extension

I also bundled the core logic into a Chrome extension so you can right-click any JSON on the web and convert it to a Zod schema or TypeScript interface instantly.

I'm actively looking for feedback! What other "local-only" tools should I add to the suite? Let me know in the comments below. 👇
