To create a redirect:
- Go to https://kagi.com/settings/redirects
- Click “Add Rule”
- In the bottom box, use the following format to create your redirect:
^https://original.domain.tld/|https://new.domain.tld/
For example, to replace www.youtube.com with inv.nadeko.net (an Invidious instance), you can use the rule
^https://www.youtube.com/|https://inv.nadeko.net/
I’ve also created a copy of this rule for any youtu.be results, as well as X/Twitter and Reddit for their respective frontends. This will work for any pair of websites if you can simply replace the domain in the URL and have it pull up the correct content on the alternative website.

You sould be able to get to it under settings > advanced > “Open Redirects”
