Generate identifiers, schedules, and test data on demand. Create v4 UUIDs and secure random tokens in bulk, build and explain cron expressions with next run previews, generate QR codes, produce TOTP codes for testing two factor flows, check password strength, and fill layouts with lorem ipsum. Randomness comes from your own browser, which is exactly where secrets should be generated.
Generate v4 UUIDs in bulk and secure random tokens with custom length and character sets.
Build cron expressions from presets, see them explained in plain English, and preview the next run times.
Generate placeholder text by the paragraph, sentence, or word, ready to paste into any design or layout.
Check how strong a password really is: entropy, character variety, and estimated time to crack.
Generate time based one time passwords (TOTP) from a secret key, the same codes your authenticator app shows.
Generate a QR code from text or a URL, entirely in your browser, and download it.
