Cookie & Storage Inspector

About

Cookie & Storage Inspector — The all-in-one browser storage editor that's actually safe.

The only free Chrome extension that lets you manage Cookies, localStorage, sessionStorage, AND IndexedDB from a single panel — with zero data ever leaving your browser.

🔒 TRUST-FIRST SECURITY
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• 100% local — no data ever sent to any server
• No debugger permission required (no scary yellow warning banner)
• Cookie access is optional — only granted when YOU click "Enable"
• Open-source, auditable code — inspect every line on GitHub
• Zero background network requests, ever

After two EditThisCookie malware incidents and the 2025 spyware wave affecting 4M+ devices, we built this with security as the foundation — not an afterthought.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🍪 FULL COOKIE MANAGEMENT
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• View, create, edit & delete cookies — including HttpOnly cookies
• Bulk selection with Shift+Click and one-click mass delete
• Global search across ALL sites (not just the current tab)
• Domain filter chips for rapid navigation
• Sort by name, domain, value, or expiry date
• Export as JSON or Netscape format (cookies.txt) for curl / wget / yt-dlp / Python scripts
• Import cookies from JSON file
• Supports partitioned cookies (CHIPS, Chrome 119+)
• Real-time cookie monitoring

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
💾 STORAGE INSPECTOR
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Edit localStorage and sessionStorage inline — no DevTools needed
• Export localStorage / sessionStorage as JSON with one click
• Smart value type detection: JSON, JWT, number, boolean, string
• Built-in JWT decoder — no need to copy tokens to jwt.io
• IndexedDB browser: view databases, object stores, and records
• Add, edit, or delete individual storage entries
• Bulk delete with checkboxes
• Search across all storage keys and values

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
⚡ DEVELOPER-GRADE UX
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Dark, professional UI — inspired by VS Code and Chrome DevTools
• Zero configuration — works immediately after install
• Manifest V3 compliant — built for the future of Chrome extensions
• Auto-detects when page has no cookies or storage (no confusing blank screens)
• Gracefully handles chrome:// and restricted pages

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
👥 WHO IS THIS FOR?

• Web developers testing authentication flows and session tokens
• QA engineers who need to switch between test accounts quickly
