Questions
Is my code executed?
No. The text is read like data and never run, so pasting unknown code is safe.
What happens to undefined, functions or variables?
undefined becomes null. Functions, variables and template literals with ${…} need running code, so the tool tells you where they are.
Is my data private?
Yes. Everything happens inside your own browser: nothing you type or choose is uploaded to us or anyone else.
Is it free?
Completely free, with no sign-up, no watermark and no limit on how many times you use it. Light ads keep the site running.
