Why it matters

Developers work with sensitive data every day. The usual options are worse than useless — they are a liability. Paste your API key into an online tool and you have just sent that key to a server you do not control. The Workbench runs entirely in your browser, so your data never leaves your machine.

Frequently asked questions

Is my data uploaded anywhere?
No. Everything runs in your browser. Your data is never sent to any server.
What is the difference between redact and anonymize?
Redact replaces sensitive patterns with placeholders (***@***.***). Anonymize replaces them with realistic but fake data (a fake email, a fake name).
Can I use the output safely?
The redacted output removes sensitive patterns. The anonymized output replaces them with fake data. Always review before sharing.
