Free Online Generators for Developers
Generators for the values developers create every day
A lot of development involves creating values on demand: a fresh identifier, a QR code for a print asset, a strong password for a new account, or placeholder text for a mockup. These generators produce those values instantly, using cryptographically secure randomness where randomness matters (UUIDs, passwords) so the output is safe to use in real systems. Everything is generated on your device — none of it is ever transmitted or stored.
All Generators for Developers
UUID Generator
Generate random UUIDs (v4) and time-ordered UUIDs (v7) online. Bulk generate up to 1000 at once and copy with one click.
Lorem Ipsum
Generate placeholder Lorem Ipsum text by words, sentences, or paragraphs. Perfect for mockups, wireframes, and design drafts.
Password Generator
Generate strong, random passwords with customizable length and character sets. All generation happens locally in your browser.
QR Code
Generate QR codes online for URLs, text, WiFi credentials, and more. Download as PNG or SVG. Everything runs locally.
When to use these tools
Use these tools to mint unique IDs for records, produce scannable QR codes for links or Wi-Fi credentials, create a strong password for a new account, or fill a design mockup with realistic-looking text.
Frequently Asked Questions
Are the generated values secure?
Yes. UUIDs and passwords come from the browser's cryptographically secure `crypto.getRandomValues`, not `Math.random`. QR codes are rendered locally and never sent to any server.
What is the difference between UUID v4 and v7?
UUID v4 is fully random. UUID v7 embeds a Unix timestamp in the leading bits, so ids are time-ordered — much better as a database primary key because they preserve insert order.
