Generators
UUID, ULID, NanoID, fake data, mock JSON, QR codes, lorem ipsum, and more.
UUID Generator
UUID generator — create UUID v4 (cryptographically random) or UUID v7 (time-ordered, RFC 9562) identifiers instantly. Bulk-generate up to 100 UUIDs at once and download as a text file. UUID v7 is ideal for database primary keys — it is lexicographically sortable and avoids index fragmentation.
Open →Lorem Ipsum Generator
Lorem ipsum generator — create placeholder text by paragraphs, sentences, or words. Standard lorem ipsum corpus for typesetting mockups, UI wireframes, and design prototypes. Copy instantly with no signup required.
Open →Slug Generator
Generate URL-friendly slugs from any text. Converts titles to lowercase kebab-case, strips diacritics (é→e, ü→u), removes special characters, and handles Unicode. Perfect for blog post URLs, product slugs, and SEO-friendly permalinks.
Open →Mock JSON Generator
Generate realistic mock JSON data from a JSON Schema. Define fields with types, constraints, and format hints (email, uuid, date, url) and get sample data for API testing, UI prototyping, and unit test fixtures. 100% client-side.
Open →ULID Generator
ULID generator — generate Universally Unique Lexicographically Sortable Identifiers. 48-bit timestamp prefix + 80-bit random component, Crockford Base32 encoded. Time-ordered, URL-safe, case-insensitive. Better than UUID v4 as a database primary key.
Open →NanoID Generator
NanoID generator — create secure, compact, URL-safe unique IDs using crypto.getRandomValues. Default 21-character IDs have the same collision probability as UUID v4 but are shorter. Configurable alphabet and length.
Open →Fake Data Generator
Fake data generator — create test data with realistic names, emails, phone numbers, addresses, company names, dates, IPs, and usernames. Bulk-generate CSV or JSON for seeding databases, testing forms, and API development. 100% client-side.
Open →QR Code Generator
QR code generator — create QR codes for URLs, text, contacts, and WiFi credentials entirely in your browser. Output is clean SVG (infinitely scalable). No watermark, no sign-up, unlimited use. Download and use on print materials, presentations, or websites.
Open →.gitignore Generator
.gitignore generator — create a .gitignore file from 20+ built-in templates for languages (Node.js, Python, Java, Go, Rust), editors (VS Code, JetBrains), and operating systems (macOS, Windows, Linux). Combine multiple templates into one clean file.
Open →License Generator
Open source license generator — create a complete LICENSE file for MIT, Apache 2.0, GPL-3.0, BSD, ISC, or MPL-2.0. Enter your name and year, choose your license, and copy or download. Includes all SPDX-standard licenses used on GitHub.
Open →Random String Generator
Random string generator that creates cryptographically secure random strings using the browser's crypto.getRandomValues, never Math.random. Pick the length, how many strings you need, and which character sets to include — lowercase, uppercase, digits, symbols — or supply your own custom alphabet.
