Privacy & network tools
Each tool explains exactly what it measures and where its limits are. Passwords and files never leave your browser.
Connection & leak tests
- 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.
Passwords
- 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.
File integrity
- File Hash Calculator: SHA-256, SHA-384, SHA-512 Online Calculate SHA-256, SHA-384 or SHA-512 hashes of files or text directly in your browser using the Web Crypto API. Files are processed locally and never uploaded.
- 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.
