I switched from Svelte/SvelteKit to Svelte/Laravel and my productivity went through the roof. Same would apply with Rails or probably other batteries included backends. SvelteKit gives you SSR but that’s it. Laravel/Rails/etc gives you database, queues, real time support, authentication, authorization, the list goes on.
I plan to make my next YouTube video making my case for why Laravel is better with Svelte than SvelteKit is https://youtube.com/@samldev
In this scenario you’d also have to pay for bandwidth since that’s the variable cost here. The more views you get, the more you pay. And obviously you wouldn’t get any money from YouTube for views since they aren’t making money from your videos.
