Why people look for a Linktree alternative
A link page exists to put your whole activity behind a single URL, the one you drop in your bios. The need is simple, but what you can actually do for free varies a lot from one tool to the next: how many blocks you get, whether you can take a payment, whether you can see your stats, and what it costs the day you want to sell something.
The question worth asking is not which tool has the longest feature list, but what you keep. If a tool sits between you and your buyer, it decides how you get paid and what you learn about your own audience. That is usually what sends people looking for something else.
