Data Residency

Where is your data stored and processed?

Flowise: Self-hosted deployment provides maximum data sovereignty—data stays entirely within your own infrastructure. Score reflects self-hosted path. Cloud product is US-hosted (score 1).

Nscale: Norwegian data centres offer EEA data residency with renewable hydropower. UK facilities planned. Customer workloads stay on Nscale infrastructure. Norway option provides strong EU data residency.

Self-hosted deployment provides maximum data sovereignty—data stays entirely within your own infrastructure. Score reflects self-hosted path. Cloud product is US-hosted (score 1).

4/5

Norwegian data centres offer EEA data residency with renewable hydropower. UK facilities planned. Customer workloads stay on Nscale infrastructure. Norway option provides strong EU data residency.

Legal Jurisdiction

Which laws govern the company and your data?

Flowise: US-incorporated company but open-source Apache 2.0 licence means self-hosted instances are independent of vendor jurisdiction. For self-hosted EU deployments, your infrastructure jurisdiction governs. Cloud product falls under US jurisdiction.

Nscale: UK incorporation provides GDPR adequacy but UK CLOUD Act equivalent (Investigatory Powers Act) applies. Norwegian data centres under EEA law offer stronger protection for EU workloads.
