IP lookup, speed testing, breach detection, password generation, and DNS security analysis — all running privately in your browser. No data stored.
Launch AppBuilt for transparency, simplicity, and privacy
Every test runs client-side in your browser. Passwords are hashed locally with SHA-1 — only a 5-character prefix is ever transmitted. Zero analytics, zero tracking.
Open the app in any modern browser and start scanning. No downloads, no extensions, no command line. Works on desktop and mobile.
Every line of code is on GitHub. No hidden servers, no obfuscated scripts. Fork it, audit it, or contribute — the source is the product.

Sign in with Google, GitHub, or email to sync results — or continue as a guest with full access to every tool.
Check your IP, test your connection speed, scan for breaches, generate passwords, and audit DNS records — one click at a time or all at once.
