Privacy tools that work, and VPN facts we can source

Free privacy & network tools

Everything runs in your browser except the IP and DNS lookups, which use our own servers and a local geolocation database. Nothing is sold or shared.

• What Is My IP Address? IPv4, IPv6, ISP & ASN Lookup See your public IP address (IPv4 and IPv6), approximate location, ISP and ASN instantly. Privacy-respecting: lookups use a local database and we don't log your IP.
• DNS Leak Test: See Which DNS Servers Handle Your Lookups Run a real DNS leak test: we observe which recursive DNS resolvers query our authoritative server, so you can confirm your VPN's DNS protection is working.
• WebRTC Leak Test: Does Your Browser Expose Your Real IP? Check whether WebRTC in your browser reveals a public IP that differs from your VPN address. Runs locally with standard browser APIs and explains each result.
• Strong Password Generator: Random & Local, Never Uploaded Generate strong random passwords in your browser with cryptographically secure randomness. Choose length and character sets. Nothing is logged or sent to a server.
• Password Strength Checker: Local zxcvbn Estimate, Nothing Sent Test how strong a password is with the zxcvbn-ts estimator, entirely in your browser. See estimated crack times and suggestions; the password is never transmitted.
• Checksum Verifier: Compare a File's SHA-256 With the Expected Hash Verify downloads by comparing a file's SHA-256, SHA-384 or SHA-512 checksum with the publisher's value. Clear pass/fail result; the file never leaves your device.
