uuidly

Generate and copy UUID v1, v4, v7, NIL and MAX in one click. Bulk up to 100 with CSV export. Offline, no tracking.

Open the popup and a UUID is already there. Click it and it is on your clipboard. That is the whole product. VERSIONS • v4 — random, the one you usually want • v1 — timestamp-based, with a random node id (your MAC address is never read) • v7 — Unix-epoch time-ordered, so it sorts lexicographically and makes a good database key • NIL and MAX — the two constants, without having to remember which is which BULK Generate up to 100 at a time. Copy them as plain text or as a JSON array, or download a CSV with proper RFC 4180 quoting and a UTF-8 BOM so Excel opens it without mangling anything. FORMATTING Uppercase, hyphens on or off, and {braces}, "quotes" or urn:uuid:. Changing the format never regenerates the value, and what reaches your clipboard is exactly what is on screen. KEYBOARD 1–5 pick a version, R refreshes, C copies, B opens bulk, Esc closes. The whole extension works with the mouse unplugged. PRIVACY uuidly requests one permission: storage, to remember your chosen version and formatting. It has no host permissions, so it cannot read or change any page you visit. It makes no network requests of any kind — a build-time check rejects the bundle if fetch, XMLHttpRequest or WebSocket appears anywhere in it. There is no analytics, no telemetry and no remote code. It is 17.6 kB of JavaScript with two dependencies, MIT-licensed, and the source is on GitHub. You do not have to take any of this on trust. https://github.com/ease-my-work/uuidly
