Do you use React? Do you need an internationalized static website? We have a brand new GatsbyJS starter supporting you out-of-box! Check out our Github.
In Ackee, we use React as the main front-end technology. Most of the time we create SPAs, but sometimes we need to create a static website with just a few pages, and an internationalization is compulsory every time. There is a lot of static site builders but if you want something easy to use with React, you should go with GatsbyJS and its huge starter ecosystem.
