Have you seen Rog Ally? It was recently released so it has newer and better hardware than Steam Deck. Unfortunately it runs Windows 11 but I'm pretty sure you can install Linux, or even Nobara Linux if you want to game on it like Steam Deck.
It has a Ryzen Z1 Extreme CPU (Zen 4), RDNA3 graphics, 512Gb storage, 16Gb RAM and 1080P 7" screen, so I think it should be good enough for web development, at least anything that doesn't need more than 16Gb RAM and a beefier CPU, but if you need that sometimes you can go cloud when you need it.
