I've been building a suite of privacy/security analysis tools. Everything runs in the browser, no data collected, no accounts:

  1. DNS Leak Test — Check if your VPN is leaking DNS queries: http://5.78.129.127/dns-leak
  2. Browser Fingerprint Check — Canvas, WebGL, fonts, WebRTC leak detection: http://5.78.129.127/privacy-check
  3. HTTP Headers Inspector — Every header your browser sends, with risk ratings: http://5.78.129.127/headers
  4. What's My IP — IP, geolocation, ISP, device detection: http://5.78.129.127/my-ip
  5. Password Strength Checker — Real entropy calculation, crack time estimates: http://5.78.129.127/password
  6. Website Security Scanner — SSL, headers, DNS audit for any domain: http://5.78.129.127/security-scan

All free. Feedback welcome — especially on what other tools would be useful for the privacy-conscious.
