Coda is the better alternative, pretty much on the same level, but with a different focus and polished at other parts I would say. Appflowy (open source) might become some day an alternative, but it's still in development, and somewhat lacking. I would give it another 1-2 years. There are also many other direct alternatives, in the sense to be a 1:1 clone, like Microsofts Loop or Zenkit Hypernotes(?), and a bunch of Open Source-Projects, but they all are very early in their development, or just lacking here an there, so I would more call them future alternatives.
