Big misunderstanding here: 
it&#x27;s not &quot;server-less&quot; (as in without-a-server), it&#x27;s Serverless (as in &quot;these products we&#x27;re trying to sell through HN&quot;...)<p>You need your users to be able to share information between them? You will need a server at some point. Period.<p>Call it miraculous AWS or whatever, it&#x27;s still a server.
