I struggled with trying to setup yourls, an open source link shortner on my limited hosting platform (cloudways). It didn't work; dumped an hour or two into it. Turned my attention to appsumo's offerings and landed with Linke. I just bought it a few moments ago; instant activation; added my custom short domain via DNS/CNAME and created my first shortened URL in like 5 minutes top. Cute QR code builder is icing on the cake. Not even sure how to use the bio links (ffff--am I that old!?) but as a local marketer this is going to be invaluable in the toolkit.
