Hey everyone,
Like most developers, I regularly need quick tools throughout the day: formatting a JSON dump, checking an expired JWT signature, calculating a CIDR subnet, or merging two PDF files.
The problem is that 90% of the top Google results for these tools are either:
- Sending your confidential strings/tokens to a remote backend API.
- Covered in popups and auto-playing ads that shift the layout.
- Slow and bloated.
So I spent the last few weeks building Omnikite — an open, zero-install workspace with 80 tools that run 100% client-side in your browser memory.
Features & Highlights:
- 🔒 Zero Data Transmission: Sensitive JSON, JWTs, and files never leave your machine. It works completely offline.
- ⚡ Instant Execution: Sub-millisecond speeds using WebAssembly (WASM), Web Workers, and the native
crypto.subtleAPI. - ⌨️ Command Palette: Press
⌘Kanywhere to search and launch any tool instantly. - ⭐ Local Favorites & Recents: Pin your daily tools with zero signup required.
- 📱 Clean UI & Dark Mode: Built with Next.js 16 App Router, React 19, and Tailwind CSS v4.
A few of the flagship utilities:
- JSON Studio Pro: Formatter, Minifier, Tree Search, and TypeScript Type Generator.
- JWT Debugger: Claim viewer and HMAC signature verifier with 0 network calls.
- Shamir's Secret Sharing: $K$-of-$N$ cryptographic secret splitting and reconstruction.
-
CIDR / Subnet Calculator: Bitwise visualizer with instant
ufw/iptablesrules. - PDF Suite: Client-side PDF Merger, Splitter, and Image-to-PDF.
- Salary & Take-Home Studio: Hourly ↔ Annual ↔ 1099 Contractor rate calculator with PTO deductions.
It’s completely free to use: https://omnikite.vercel.app
I'd really appreciate any feedback, bug reports, or suggestions for new tools!
