I've been building managed hosting for this exact category of agent systems. The supervision/persistence angle is what drew me to it.
My stack is Elixir on Fly.io — OTP supervision trees are basically purpose-built for long-running processes that need to stay alive. If something crashes, the supervisor restarts it. No systemd, no cron, just the runtime doing what it was designed for.
The self-hosting path is great for tinkering — and Karpathy's point about NanoClaw's ~4000 lines being auditable is a solid trust argument. But once you want 24/7 uptime across multiple agents, you end up rebuilding production infrastructure from scratch.
I run 5 Elixir apps on Fly for under €50/month, so the economics of multi-tenant hosting work well here.
(Founder of OpenClawCloud — clawdcloud.net — happy to talk architecture if anyone's exploring this space.)
