The Landr team believes in a zero configuration approach. We think Landr should be able to determine what you have and how to present it in the best possible way. We know this is a very ambitious goal, and if you think something is off, reach out to us! Whatever you have in mind, we can try to teach Landr about it, which benefits the community more than adding a configuration flag.
Sure! Landr generates static HTML, CSS, and JS. You can add more files to the bundle as you wish before pushing them to Netlify.
Netlify can do everything that GitHub Pages can do, and it also provides some extra features and flexibility that we find really valuable for Landr, such as being able to deploy more than one branch of a site at the same time, A/B testing, form submissions management, and more. On top all of that, Netlify is free to use!
