It's very sad to see Aviary go and didn't choose to continue pushing their web editors to a more advanced audience and photo hobbyists. If they're abandoning plans moving forward in the web, Polarr (https://www.polarr.co/) might just be the last player trying to push web photo editing experience. It always seems like the web has not done with photo processing yet though companies are all jumping into mobile these days or moving on to video processing.
