Deep Dive: Switching from v0 to Onlook
Trade-offs, installation & data architecture
What you trade away

How to deploy Onlook
Hosted signup, or self-host with Bun or Docker plus Supabase configuration
What it takes to run
Hosted access may be gated; self-hosting needs Bun or Docker, Supabase and several environment variables
Where your data lives

The hard boundary is vercel models, design tuning, component data, deployment, and ecosystem integration, plus frontier models, context infrastructure, and execution safety.
