Building this?
Read ten of the asks above first, because they say what the existing launches miss. If you ship it, post it as a Show HN so the next run of this list finds it.
Ship it like Vercel, on a server you own
This site runs on ShipTiffin. A push to GitHub deploys it, the way it would on Vercel, but the server is a Hetzner box in your own account. Postgres, sign-in, email, jobs and analytics are already on it, every project gets a hard limit, and nothing is billed by usage.
$19 a month per box, plus about $10 for the server at Hetzner. Open source, so you can also run it yourself for free.
