Where does the airship dock? Four candidates costed at three scale tiers (research/2026-07-30-hosting-infra.md, with sources): - Cloudflare Workers + for SaaS: ~$5 / ~$10 / ~$150 per month — custom hostnames ($0.10/mo after 100 free) are the only real scale cost, and they track paying users at ~2% of revenue - Hetzner VPS + Caddy on-demand TLS: cheapest at every tier, keeps literal SQLite+Litestream, wisp.place recipe proven — but makes a nights-and-weekends solo dev the 24/7 ops team (PD-7) - Vercel: $20/mo floor before the first paying user, wildcard requires surrendering mooring.page DNS, worst scale curve - Fly.io: dominated on cost and reliability; LiteFS sunset ADR 0011 (Proposed, awaiting ratification): Cloudflare Workers as hosted target; D1 finalizes ADR 0010's provisional SQLite (file + Litestream in self-host mode); VPS+Caddy documented as first-class self-host path and escape hatch; wisp.place-style DID-in-TXT domain verification; one named spike (oauth-client-node under nodejs_compat, @atcute fallback) before scaffolding commits. Also queued in NEXT: item 2 is now "ratify ADR 0011". Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014mXNfP5m9NhhjVgM5VVJ5E
