PixelVault
A privacy-first security and developer tools platform — featuring AES-256 encrypted LSB steganography and 55+ client-side utilities across five categories. No data ever leaves the browser on tool pages.
Steganography + 55 developer tools — all client-side
PixelVault is a web platform built on Laravel 12, Inertia.js v2, and Vue 3. Its core feature is LSB (Least Significant Bit) steganography with AES-256-GCM encryption — hiding encrypted messages inside images entirely in the browser using the native Web Crypto API. No image, message, or key ever touches a server.
Around that core, 55+ developer utility tools span five categories — developer utilities, image and design tools, SEO and network tools, AI-powered tools, and productivity tools — all processing data locally in the browser with no account or rate limits required.
