Generate
Generate RFC UUIDs, validate pasted IDs, build strong passwords, random strings, numbers, mock JSON fixtures, and QR codes entirely client-side. Useful for seeds, test users, and dummy API payloads without a faker backend.
UUID Generator
Generate RFC 4122 UUIDs (v4 and v7) in bulk, or validate and reformat pasted IDs. Copy a list for database seeds, test fixtures, and idempotency keys. Uses the Web Crypto RNG so IDs are created on-device with no telemetry.
Password Generator
Create strong random passwords and passphrases in your browser. Tune length, symbols, and ambiguity, then copy once. Generation uses local randomness and never phones home. A private generator for accounts, test users, and sharing secrets over a side channel you control.
Random String Generator
Generate random alphanumeric strings with a charset and length you choose. Handy for tokens, test IDs, and dummy keys. Uses local randomness so generated values are not logged by a hosted generator.
Random JSON Generator
Generate nested JSON fixtures for mocks and tests. Tune depth and item count, then copy a valid object or array. Built with the Web Crypto RNG so dummy payloads are created on-device.
Random Number Generator
Pick random integers or decimals in a min–max range, one at a time or in a list. Simple test data and dice-style rolls without a remote RNG. Generated on your device.
QR Code Generator
Encode a URL or any text as a QR code in the browser. Tune error correction, size, and colors, then download PNG or SVG. Encoding stays on the device. There is no QR API.
