Dominique,

You should be able to use Gatsby Source WordPress v4 anywhere you use Gatsby.

Gatsby Cloud is the only platform that’s fully dedicated to the Gatsby Experience, so while you can use Gatsby on Vercel, Netlify, or other similar services, some features like Incremental Builds and Preview will likely not work on other build services, because they don’t have the infrastructure setup to support these features.

We’re always working on making Gatsby builds run faster on ALL platforms, but Gatsby Cloud has a lot that it can do to speed things up further that only a dedicated platform can deliver.
