FAQ
Is Canonical & Hreflang really free?
Yes — free with no signup, no credits and no limits on this tool. It is supported by clearly labeled ads placed away from the buttons, never by paywalls.
Is anything I type into Canonical & Hreflang sent to a server?
No. Every keystroke is computed with a pure JavaScript engine (Web Worker for heavy inputs) inside this page. Close the tab and your data is gone — unless you explicitly download or share it.
What should I enter in "Self"?
Put your self here — for example: https://example.com/x. Leave the defaults first to see how it works, then adjust. Every field is validated with a plain-language message if something is off.
I normally use SmallSEOTools — why switch?
If you are tired of one generator per tab across ad-heavy thin pages, SiteKit is the alternative: one input into meta plus Open Graph plus JSON-LD plus preview plus copy, with validation.
How accurate is Canonical & Hreflang?
Everything runs on your device, so results are instant and repeatable — same inputs, same outputs, no server involved.
