One of my favorite “go-to” sites for quickly accessing translations is BibleGateway. They also have apps for your smartphone.
I like it on my computer because when I need a quick reference to view a verse in several different translations, this site is the easiest for me. I can type in the reference and go to it, then add parallel passages easily. They have an incredibly thorough list of English translations. They were also one of the first to utilize the Common English Bible, which is one of my favorite newer translations.
They also have decent study aides. One of my favorites is the IVP series. It’s nice to have a quick synopsis of what is going on in the passage.
BibleGateway is the busiest site for Bible reading for a reason. For me, it’s because it offers the quickest access to a wide range of translations.
