Free Web Tools
A growing set of fast, privacy-first tools for everyday security and development tasks. Everything runs entirely in your browser — nothing is uploaded.

Built for privacy and speed
Every tool here runs 100% client-side. There's no sign-up, no upload, and no tracking of what you type. Open your browser's Network tab and you'll see these tools make no requests with your data — the one exception is the optional password breach check, which uses a privacy-preserving k-anonymity model that never sends your actual password.
