UUID Generator

PREMIUM — PURCHASE REQUIRED: All features described below are part of Pro and require a purchase: a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase. You need a UUID right now — for a database seed, an API test, a config file — and you're on your phone. Tap once, and a fresh RFC 9562 UUID is on screen with a copy button beside it. No laptop, no website, no signal required. UuidGen generates every identifier on your device using the system's cryptographic random source. Pick v4 for the everyday random default, v7 when your IDs need to sort by creation time, v1 for classic timestamp-based IDs, or v5 to derive the same deterministic ID from a namespace and name every single time. The terminal-green, monospaced interface feels at home next to the rest of your toolchain. WHAT YOU GET • One tap and a fresh UUID is ready to copy — pasted into your code seconds later • A batch of 5, 10, or 50 unique IDs in a single tap when a seed script needs more than one • v5 namespace IDs (DNS, URL, OID, X.500) that come out identical every run — same input, same UUID • Format toggles for UPPERCASE, no-hyphen, and {braces} that re-render the current ID instantly • CSV or JSON export of your generated IDs, ready to drop into a repo, ticket, or test fixture • Your last 100 IDs kept on this device — searchable, one-tap copy per row or copy-all at once PERFECT FOR • Backend and mobile developers seeding databases or mocking API payloads • QA engineers who need unique test IDs mid-session without reaching for a laptop • DevOps and support staff filling in config values and correlation IDs on the go • Anyone learning how UUID versions differ — each version explains itself in one line WHY NOT JUST A WEBSITE? A web generator needs a connection, surrounds your IDs with ads, and you cannot see where its "random" actually comes from. UuidGen works in airplane mode, draws every random bit from your iPhone's secure random generator, and never sends a single ID anywhere. PRIVATE BY DEFAULT Everything happens on your device. No account, no network calls to generate, no analytics on your identifiers. Your history lives in local storage until you clear it. PREMIUM (PURCHASE REQUIRED) UuidGen is unlocked with one plan of your choice: a Weekly subscription, a Yearly subscription, or a one-time Lifetime purchase. Every plan opens the entire app — all UUID versions, batch generation, format toggles, history with search, and CSV/JSON export. Download UuidGen and put your first batch of UUIDs on the clipboard in the next thirty seconds.
