Cloudflare Pages is pretty good, it's for server-side rendering as well, and have things like Durable Objects that no one else have, and D1, which is built on SQLite. Sending emails is also free with Cloudflare Workers. No egress fees. Best of all fully-local development and testing is supported with an open-source runtime you can also deploy on your own, albeit without Cloudflare's edge-first infrastructure.
Not affiliated with them, just my 2 cents.
