I use Arkane Linux, which is based on Arch but is immutable. Every update is a new install. You can easily configure custom images to deploy for your specific wants or needs. It’s nice for keeping up to date with Arch while keeping how my machine is configured declared in an image. You can always roll back if something was wrong with the image you deployed too.
Not using Kagi because its an American company is valid. But people are too used to products that are free because they make the person using them the product. There is still a transaction with a free product.
Kagi is not free because they respect your privacy and don’t sell your data.
