AI often generates parts of code for my hobby projects, which allow me speed running with my implementation. It often generates errors, but I am also skilled, so I fix error in the code.
I use AI as boiler plate code generator, or documentation assist, for languages I do not use daily. These solutions I rarely use 1:1, but if I had to go through readme's and readthedocs, it would take me a lot longer.
Would there be more elegant solutions? often - yes. Does it really matter? For me - not.
Vercel's pricing is so ridiculously convoluted that you can't even cleanly compare usage. With render/railway/(insert provider of choice) you can at least predict that you're your biggest cost is going to be egress.
edit: I just saw that it gets 450m pageviews. I'm guessing on the upper end this costs ~$1k with railway + cloudflare?
