Nine tools for producing something you need right now — a password, a placeholder identifier, a hash, a scannable code — without an account, a history log, or a rate limit that kicks in on the third try.
Security and identifiers
The password generator builds strong, random passwords with configurable length and character sets, using your browser's cryptographically secure random number source — the same quality of randomness a password manager would use. UUID and SHA256 generators produce standard-format identifiers and hashes for development and testing work.
The one server-side tool
Every generator runs entirely in your browser except Bcrypt Hash Generator, which submits your input to the server because Bcrypt hashing needs a real backend implementation — there's no equivalent JavaScript primitive that matches it. Nothing you submit is logged or stored.
Test data, not production data
Credit Card Generator produces numbers that pass the Luhn checksum — the same arithmetic check real card numbers satisfy — but aren't issued against any real account, so no payment processor will ever authorize a charge against one. They're for testing checkout forms and validation logic, not real purchases.
Everyday utilities
Lorem Ipsum for placeholder copy, Base64 for encoding binary-ish data as text, QR codes for links and Wi-Fi credentials, and Open Graph tags for how a page previews when shared on social platforms — small, focused tools you reach for once and move on.
