Is local-first local-only actually harder to build and secure than a four-nines uptime service?

I understand that it's less profitable, which is the real reason nobody does it.

Building and securing local first is definitely harder than four-nines.

Want 99.99% uptime? Easy.

Cloudflare, AWS, fly.io, Vercel etc. have poured decades of person-years of engineering into platform reliability and operational excellence so you can get it with a few quick CLI commands.

Just because the infra you built on top of is 99.99% uptime doesn't mean that your application is.
