The problem I have is I know the differences between Electron and Meteor but I don't know how Gatsbyjs fits with that or if its completely different and if Gatsby can be used with Meteor or Electron.

I am creating a web application using HTML, CSS, and react-redux and I want to have it built across all platforms desktop (Mac, Linux, Windows) and iOS/iPadOS. Also I am using Netlify to upload my webite which I already have a domain for.
