FAQ
Is Security Headers Builder really free?
Yes. No account or credits are required, and no paywall blocks the task. Browser, device, and stated file-size limits still apply. Ads may appear only when configured and enabled after the required consent signal.
Is anything I type into Security Headers Builder sent to a server?
The calculation runs in this page and is not sent to a Tolari processing server. Depending on your settings, recent runs may be saved in local browser storage; use Private Mode or clear local history on this device if needed.
What should I enter in "Domain"?
Put your domain here — for example: example.com. Leave the defaults first to see how it works, then adjust. Every field is validated with a plain-language message if something is off.
How should I compare Security Headers Builder with other options?
Compare supported inputs, output quality, file-size limits, browser compatibility, and privacy terms using the same sample. Provider features and terms can change; check their current documentation.
