I would consider the best features that Netlify Platform offers to be that it is a worthy rival to Vercel because, just as that platform does, these platforms allow you to quickly deploy web projects from repositories and the user interface is very easy to use; I'd say that's one of the most useful things about Netlify Platform, and that many features are free. It easily allows you to make secondary deployment environments to, for example, test certain features in staging that you may have implemented.
Regarding the ease of use that I mention, the aspects of the interface or the deployment process that I find especially intuitive or that save me the most time include the fact that it automatically has a CI/CD flow where I deploy, and automatically—that is, I push the code to GitHub, in this case, I have it hosted there—and it automatically starts building the application and it is deployed immediately. It also allows me to easily configure environment variables and also how the application is built.
In the case of my family business, the main benefits or positive changes I've noticed since using Netlify Platform include that it saves me headaches, such as what I mentioned about deployment and building the application. Before, I did it with GitHub Pages, but it's a system that's a bit more rigid, so to speak. With Netlify Platform, I can easily deploy one or several projects, change application settings, and have several versions in the same place.
Since I migrated to Netlify Platform, I have noticed time savings, error reduction, and improvements in efficiency because if there is any error when building the application, it notifies me quickly, and I can see exactly what is failing, which with GitHub Pages was a bit more complicated.
