FAQ

Frequently asked questions

Should .env files be committed?

Real .env files usually contain secrets and should not be committed.

What belongs in .env.example?

It should list variable names and safe placeholders, not production secrets.

Can values or comments stay visible?

Comments remain unchanged. The public-value mode can also retain values based on their variable names, which does not prove they contain no secrets. Review the full output before sharing.

Are my inputs sent to a server?

OnSubmit tools run in the browser whenever the task can be processed locally. Avoid pasting production secrets, real banking details or personal data into public tools.
