We have known the saying for years: the cloud is just someone else's computer. But in 2026, it is more than a quip — it is a genuine attack surface.

Three major outages in Q1 2026 (two AWS regions, one Cloudflare incident) reminded us that digital infrastructure is fragile by design when it is concentrated. Most startups do not even own the keys to their own data. They can't. The tooling was never built for it.

What changed is that self-hosting is no longer painful. Cheap ARM servers, NixOS reproducible configs, WireGuard mesh networking, and tools like Tailscale mean a single person can now run infrastructure that is genuinely sovereign. Not "self-hosted on AWS." Actually yours. The gap between "enterprise-grade" and "what one engineer can run at home" has collapsed in the last three years.

The question is not whether self-hosting is feasible. It is. The question is: why are so few developers treating it as the default, not the exception?

What is actually stopping you from running your own stack in 2026 — complexity, time, trust in providers, or something else?
