Prompt it and you get React and Tailwind components that paste straight into a Next.js project, then ship to production in one click, a very short path from idea to live page. The free plan allows 5 dollars of credits and seven messages a day, and Plus costs 30 dollars per user monthly. Vercel Inc. builds it under California law, and the output assumes you already work in their stack.

Choose Capacity if…
- You want a provider governed by a European privacy regime
- GDPR or public-sector data-protection requirements apply to you
- You'd rather back the European tech ecosystem
Stick with v0 if…
- You depend on integrations only available in the Vercel ecosystem
- Your organisation has no EU data-residency constraints
- Migration costs outweigh the jurisdiction benefits for now
Why choose Capacity over v0?
The decisive argument is data jurisdiction. v0 is headquartered in the United States, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
Capacity removes that overhead. As a France-based provider, it operates under EU GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single jurisdiction that can change the rules without warning.
