Developer & Test Data Tools
35 free generators, no sign-up needed.Developers spend a surprising amount of time inventing plausible data. Card numbers that pass a Luhn check, passwords that satisfy a policy, UUIDs, hashes of a known string, IMEI and VIN numbers that look right to a validator. This category collects the tools that produce that data in one click.
Everything generated here is synthetic. Card numbers are not linked to real accounts and will not authorise a payment; they exist so you can test what happens when someone types a valid-looking Visa number into your form. Treat the outputs as fixtures, not as anything with real-world value.
