Found out, you should not post on HN a vercel app running an hobby plan, as you quickly reach KV store usage limit. Fair :)
But upgrading vercel was not a smooth experience : https://twitter.com/skeetmtp/status/1748702685325398388
I'm pretty interested in this kind of solutions. But I don't really see the real advantages vs a vagrant based setup ? You can already do filesharing and changing port fw only happens once in a while, in my case.
