Jalview is described as 'Free cross-platform program for multiple sequence alignment editing, visualisation and analysis. Use it to align, view and edit sequence alignments, analyse them with phylogenetic trees and principal components analysis (PCA) plots and explore molecular structures' and is an app in the education & reference category. There are five alternatives to Jalview for Mac, Windows and Linux. The best Jalview alternative is PyMOL. It's not free, so if you're looking for a free alternative, you could try Avogadro or Jmol. Other great apps like Jalview are Rasmol and ChimeraX.
