Contact
Toolzen doesn't run a contact form, because without a backend server a form here would only be able to pretend to submit — and we'd rather be upfront than fake it. The fastest way to reach us is by email.

Response Times
Toolzen is maintained by a small team, so please allow a few business days for a reply. Bug reports and specific, reproducible issues (for example, "the JSON formatter mis-reports the error line when the input starts with a byte-order mark") are the fastest for us to act on. General tool suggestions are also welcome — many of Toolzen's future tools will come directly from reader requests.
