I got a wave of shudder reading the acronym "HAM stack". Yugh. MEAN, MERN, RERN–once hyped up hot air which now sounds so dated and hackneyed. It's cool to be excited about tech but if your main selling point is building "faster and cheaper", I don't know if picking up a minimalistic framework you know nothing about is faster than just re-using your trusty boilerplate.

Be it React or Svelte or whatever. With serverless backend if you want to keep costs down. Although a server from Hetzner isn't that expensive and you can host multiple APIs there.
