Overview
Right click any field and fill it with a valid UUID, ABN, TFN, IBAN or password. No network, no page reading.
Testing a form needs a value that passes validation, and the usual ways to get one are worse than they look: a made up number gets rejected, and a real one belongs to somebody. Right click any editable field and pick what it should hold. - Identifiers: UUID v4, v7, v1 and v6, ULID, KSUID, MongoDB ObjectId, Nano ID - Australian: ABN, ACN, TFN, Medicare number - New Zealand: IRD number, NZBN - Banking: IBAN, from a different country each time - A 20 character password over all four character classes Every identifier passes the real check digit algorithm it is meant to, and is issued to nobody. That is what makes it test data: valid enough for a form, attached to no person or business. It asks for no access to any website. There is no content script, and no host permission is requested, so nothing of this runs in a page until the moment you pick something from the menu, and then only in the frame you clicked. It never reads the page it lands in, and it makes no network request of any kind: every value is computed on your machine and forgotten. The same generators, with more options and an explanation of each, are at https://huu.app.
