I really like the swap service of https://deezy.io/ which is https://swap.deezy.io/.

I still remember when I started with Lightning that everything was overwhelming:
"How do I get sats into lightning? How do I get sats out of lightning? How do I get inbound liquidity? Which channels to open?"

But https://deezy.io/ seems to have answers to all of that.

And at some point, I realized that Phoenix has loop-out integrated into the wallet. But the fees on https://swap.deezy.io/ are sometimes better.

(I can only speak for the swap service though since that's the only thing I used so far from deezy)
