Generators for developers
Six tools for when you need something that does not exist yet: an ID for a new row, a password for a service account, a QR code for the office WiFi or a slug for the post you are about to publish. The UUID generator produces up to 500 at once as v4 or v7, or as ULID and NanoID when you want something shorter or sortable by date.
For layouts and tests, lorem ipsum gives you paragraphs, sentences or words, wrapped in <p> if you need HTML, and the mock data generator builds up to a thousand rows of names, emails, Spanish IDs and IBANs that agree with each other, as JSON, CSV or SQL. With a seed you get the same rows every time, so a test that fails today fails the same way tomorrow. Passwords come from crypto.getRandomValues and are never stored.
All 6 tools
- UUID generatorGenerate up to 500 UUID v4 or v7, ULID or NanoID at once and check any identifier: version, validity and the date it carries.
- Lorem ipsum generatorGenerate Lorem ipsum placeholder text by paragraphs, sentences or words, starting with “Lorem ipsum dolor sit amet” or not, as plain text or HTML <p>.
- Mock data generatorGenerate up to 1000 rows of consistent fake data (name, email, Spanish IDs, IBAN, address…) as JSON, CSV or SQL. With a seed, always the same.
- Strong password generatorGenerate strong random passwords with crypto.getRandomValues, choose length and character types and see their entropy in bits. They are never stored.
- QR code generatorCreate QR codes for text, links or WiFi networks in your browser and download them as PNG or SVG. With accents, emojis and the error correction you choose.
- URL slug generatorTurn titles into clean URL slugs: no accents or symbols, with the separator you choose and without splitting words. One line, one slug.
