Technical edge cases & frequently asked questions
Is my input sent to a server?
No. These tools run entirely in browser JavaScript with no external processing.
What are the limits?
The calculator handles the nine standard rwx bits, not setuid, setgid or sticky bits. Commands are never executed.
Are commands executed?
No. Commands and configuration outputs are plain text for you to review and copy.
Can I download the output?
Yes. Copy or download the generated result in the selected format. Large env inputs use a cancellable local worker.
