@villapirorum @linkstack It's been years since I moved from Linktree to Linkstack, but I remember Linktree having inserted all kinds of limits and restrictions, trying to lure you to switch to a paid subscription.
You can set up a Linkstack page as you like using its CMS, inserting different kinds of link entries, text headers, etc., and choose from a range of design templates. And it's totally free, although donations support the maintenance of the platform.
