Bugs, wrong output, a tool you wish existed, or a question about the privacy policy — all of it goes to the same inbox.

Please put the tool name in the subject line, for example JSON to Go Struct — wrong type for nested array. If you are reporting incorrect output, the input that produced it is the single most useful thing you can include. It is safe to send: nothing on this site stores what you paste, so there is no copy on our side to compare against.
What gets fixed fastest
- A tool producing output that is simply wrong, with the input that shows it.
- A page that breaks on your phone or browser, with the device and version.
- A tool that claims to do something it does not do — accuracy of the description matters as much as the code.
Security
If you believe you have found a way for this site to leak tool input off the device, that is the highest priority class of bug here — it would contradict the entire premise of the site. Please describe the steps to reproduce it rather than only the symptom.
