Choose Capacity if…
- You want your data to stay under EU law without extra legal paperwork
- GDPR compliance or public-sector requirements apply to you
- You'd rather back the European tech ecosystem
Stick with v0 if…
- You depend on integrations only available in the v0 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 US, 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 natively under 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 non-EU jurisdiction that can change the rules without warning.
