1. Their logo sits under your name
Linktree keeps its logo and a "Made with Linktree" footer on every free page, and removing it means moving up a tier.
What fixes it: Nobody, on a free plan. Every tool here brands its free tier — what differs is the price to remove it, and Carrd is the cheapest at $9/yr. We are no better: pages published on Stick carry a Stick badge, and removing it is not available yet. If a clean page is what you are switching for, this is not the reason to switch to us.
