Generator Tools
Produce placeholder text, unique identifiers and strong passwords — every byte generated locally with the browser's Web Crypto API. Open DevTools → Network and confirm: no request leaves your tab when you click a button.
Random data, never with Math.random()
Three generators backed by crypto.getRandomValues() (UUID v4, passwords) and the canonical Cicero source (lorem ipsum). No Math.random() anywhere — it's not suitable for credentials or opaque identifiers. UUID v7 is supported when you need a timestamp-sortable primary key.
Start with Lorem Ipsum Generator for placeholder text, Password Generator for credentials, or UUID Generator for identifiers.
Frequently Asked Questions
How are random values (UUID, password, lorem) generated?
UUID v4 and passwords use crypto.getRandomValues() (Web Crypto API), a cryptographic entropy source provided by the operating system. Lorem Ipsum uses the canonical Cicero text truncated and permuted — that's the standard usage, not random generation.
UUID v4 vs v7 — which should I use?
v4 is pure random, ideal for opaque identifiers (tokens, session IDs). v7 is sortable by embedded timestamp, optimal for database primary keys (better index locality, smaller B-tree depth). The UUID generator supports both.
Can I bulk-generate (100+ UUIDs or passwords at once)?
Yes — up to 1000 UUIDs in one go. Bulk password generation is rarer in practice, so it's capped to smaller batches by default. Everything still runs locally.
When will QR code, favicon and avatar generators be available?
Planned — see Coming next on this page. QR code lands with tool-saturation-dev-v1 (vendor lib shared with the upcoming TOTP generator). Favicon and avatar generators ship in tool-saturation-generators-v1. All three will run client-side, no upload.
Can I customize the output format (uppercase UUIDs, no dashes, etc.)?
Yes — each generator exposes its options. UUID: uppercase, no dashes, with braces. Password: charset, length, exclude ambiguous characters. Lorem: paragraphs, sentences, words, with or without the canonical "Lorem ipsum dolor sit amet" opener.
