Frequently asked questions
Can I search by name?
Yes — search by code (e.g. 404) or by name (e.g. 'gateway', 'redirect').
Is it private?
Every calculation happens on this page, in your own browser. Your input is never sent to a server, never logged and never used for training — which also means the tool keeps working when you are offline.
