Coolify vs OpenNext
Self-host pick — both replace Vercel (Frontend hosting / serverless deploy).
Both Coolify and OpenNext self-host as a replacement for Vercel (Frontend hosting / serverless deploy). Pick Coolify if you want the lighter footprint — 10min (single-line bash installer), $10 vps for the controller + however much you need for the apps it runs. Pick OpenNext if you need next.js apps that want to deploy to AWS or Cloudflare Workers without giving up Next features — 15min (build adapter; deploy target is your choice) and $0 framework cost; pay for whatever cloud you target (aws, cloudflare, etc.

Good fit for
Coolify
Solo devs and small teams who want a Vercel-feeling PaaS on a VPS.
Weak at:No global edge network — single-region; no instant preview-per-PR.
OpenNext
Next.js apps that want to deploy to AWS or Cloudflare Workers without giving up Next features.
Weak at:It's an adapter, not a UI — you still need to wire the deploy pipeline.
In a terminal? npx -y github:SolvoHQ/os-alt-cli vercel prints Vercel's self-host options including both —
