Generators

Sometimes you need a fresh value on demand: a unique identifier for a database row, a strong password, a checksum to verify a download, a QR code for a link, placeholder copy to fill a mockup, or a cron expression for a scheduled job. These generators produce them instantly and, where randomness matters, use the browser’s cryptographically secure random source rather than a predictable pseudo-random one. Identifiers follow their specs (UUID v4 and the time-ordered v7), hashes come straight from Web Crypto, and every generator explains the trade-offs — entropy, collision odds, error-correction levels — so you can pick sensible options instead of guessing.

UUID Generator (v4 / v7)Generate random v4 and time-ordered v7 UUIDs online, free and private. IDs are created in your browser with a CSPRNG and never sent anywhere.Password GeneratorGenerate strong, random passwords in your browser with adjustable length, character sets, and a live entropy readout. Private and offline, nothing is sent.Lorem Ipsum GeneratorGenerate lorem ipsum placeholder text by paragraphs, sentences, or words. Free, private, and fully in-browser — copy classic filler for mockups instantly.Hash Generator (MD5/SHA-1/256/512)Generate MD5, SHA-1, SHA-256 and SHA-512 hashes from text in your browser. See all four digests at once, computed locally so nothing is uploaded.QR Code GeneratorGenerate QR codes from any URL or text in your browser, free and private. Tune error correction and download a crisp, scalable SVG — nothing is uploaded.Slug GeneratorTurn any title or heading into a clean, URL-safe slug. Strips accents and punctuation, collapses spaces to hyphens, and runs entirely in your browser.NanoID GeneratorGenerate short, URL-friendly NanoIDs online with a secure random source. Set the size, count, and alphabet, then copy compact unique IDs, all in-browser.Random Number GeneratorGenerate random numbers online in any range with a cryptographic RNG. Pick integers or decimals, unique sets, and bulk counts, computed in your browser.Meta Tag GeneratorGenerate SEO meta tags, Open Graph, and Twitter card markup from a title, description, and image. HTML-escaped output you can paste, all in-browser.
