Closest thing to true “serverless”: entire MVC app (Django/Rails/Laravel) in the browser with WASM and data persistence by SQLite over CDN.

All the server has to do then is serve binaries, all the business logic is in the client.

Brilliant… but now you need to validate that the client did all their business logic correctly without tampering. That alone can be so complex it defeats the point.

No... you don't need that. Not for the overwhelmingly vast majority of cases. Let people use their own software. Tampering? Not my problem. Let people do it if they want.

The "overwhelmingly cast majority of cases" will be an employee of a larger company, a person/computer that cannot be trusted with arbitrary access to data and exceptions to business rules in code.

If it's a single-user app, you can only load data the user actually needs and is cleared to access. And/or lock down the device.

Multi-user app (and if we're talking about companies, it's multiple users by the very definition) where users are not trusted almost always needs either a central service with all the access controls, or a distributed equivalent of it (which is, indeed, very hard to implement). “Local-first” in those cases becomes less relevant, it’s more of a “on-premises/self-host” in this case.

But I think while end-user non-business software can be small compared to enterprise stuff, it is still a fairly big market with lots of opportunities.
