About CrispUtils
A small set of genuinely useful browser tools, built to be fast and free of the account walls and dark patterns that clutter most "free tool" sites.
What this is
CrispUtils hosts a growing set of single-purpose utilities — a JWT decoder, a cron humanizer, an IBAN validator, and others — each on its own page, each running entirely in your browser. There's no upload step, no account, and no waiting on a server: the calculation happens the instant you type.
How it's funded
This site is supported by advertising, shown around the tools rather than inside them. We don't sell data because we don't collect any — see the privacy page for specifics.
