CookieVault

Minimal cookie management for security researchers and web developers.

CookieVault gives you complete control over your browser's cookies — directly from your toolbar. No developer console, no complexity. Just a clean, focused interface that gets out of your way. ────────────────────────────────────── FEATURES ────────────────────────────────────── ▸ Real-Time Cookie Inspection View every cookie tied to your active tab the moment you open the extension. Name, value, domain, path, expiration date, and all security flags are displayed at a glance. ▸ Inline Editing Click any cookie to edit its value or expiration date without leaving the popup. Changes are applied instantly to your browser session. ▸ Add Custom Cookies Create new cookies from scratch with full control over all attributes — including Secure, HttpOnly, SameSite, and custom expiration. ▸ Import / Export (JSON) Export all cookies for the current site as a clean, human-readable JSON file. Import previously saved sessions to restore state instantly. File names automatically match the site (e.g. youtube.com_cookievault.json). ▸ One-Click Clear Remove all cookies for the active domain in a single action. Useful for resetting sessions or reducing your tracking footprint. ▸ Security Flag Visibility Instantly see which cookies are marked Secure, HttpOnly, or SameSite — critical indicators for session security analysis and XSS/CSRF assessments. ▸ Smart Search & Filters Filter cookies by HttpOnly, Secure, or Expired status. Search across names, values, and domains in real time. ▸ Dark & Light Mode Automatically matches your system theme on first launch. Switch anytime from the Settings tab. ────────────────────────────────────── WHO IS IT FOR? ────────────────────────────────────── Web Developers — Debug session bugs, test different authentication states, and inspect cookie behavior across environments without opening DevTools. Security Researchers — Audit how websites set and protect cookies. Identify missing HttpOnly or Secure flags, weak SameSite policies, and overly permissive cookie scopes. QA & Automation Engineers — Simulate specific user states by injecting or modifying cookies, then export that state as a reusable JSON file for your team. Privacy-Conscious Users — See exactly which cookies are tracking you on any site, and remove them instantly. ────────────────────────────────────── PRIVACY & SECURITY ────────────────────────────────────── CookieVault operates entirely locally on your device.
