What is a better substitute for Sandvox?

One of my websites was made with iWeb and then Sandvox. Sandvox did work but with constant shut downs until recently. I had started a new website but would like to maintain the old one as well. Is there a suggested app to use so that I can still edit the site? I found Everweb as a substitute but before I started paying for software again I wanted to ask for suggestions.
