Onshape: sovereignty score and 8 European alternatives

Onshape is a cloud-native product development platform that combines 3D CAD, product data management (PDM) and real-time collaboration. It covers parts, assemblies, drawings, sheet metal and surfacing, plus release management, branching and merging, and bills of materials. Related tools include CAM, simulation, rendering and an AI Advisor, and it connects to PLM systems such as Arena and Windchill. It is delivered as software as a service: users work in a web browser or in iOS and Android apps, with no installation, and the vendor rolls out updates.

Onshape was founded in 2012 in Cambridge, Massachusetts, and PTC, a US company, acquired it in 2019. The platform runs on Amazon Web Services. The pages consulted do not list specific AWS regions or an EU data-residency option; Onshape Government is a separate offering built on AWS GovCloud. Onshape reports an annual SOC 2 Type 2 audit, with the report available under NDA. US law, including the CLOUD Act, can apply to data held by US providers, so ask in writing where design data is stored and which sub-processors are used.

Why digital sovereignty matters with Onshape

Onshape is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Onshape hosts data in EU, OTHER. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

Onshape is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Onshape together with your other vendors and gives a total score, a heatmap and the main risk drivers.
