The Case for Windmill
- Windmill stores all data exclusively in EU, under European jurisdiction. Unlike Zapier, which is subject to the US CLOUD Act and FISA Section 702, Windmill cannot be compelled by foreign governments to hand over your data.
- Windmill offers a Data Processing Agreement (DPA) that is fully aligned with GDPR Article 28. There is no legal ambiguity about data transfers or adequacy decisions — your data processor is European, and the law that governs it is European.
- As an open-source solution, Windmill gives you full code transparency. You can verify that the software does what it claims, audit it for security vulnerabilities, and even self-host it for maximum control — something that is simply not possible with Zapier.
- You can try Windmill for free before committing. This makes it easy to evaluate whether it meets your needs alongside — or as a replacement for — Zapier, without any financial risk.

Windmill vs Zapier — FAQ
Is Zapier GDPR compliant?
Zapier may offer GDPR compliance features and EU data residency options, but as a US-headquartered company, it remains subject to the US CLOUD Act and FISA Section 702. These laws can compel US companies to hand over data regardless of where it is stored. The EU-US Data Privacy Framework provides some safeguards, but its predecessors (Safe Harbor and Privacy Shield) were both invalidated by the European Court of Justice. Windmill, as a European company, is not subject to these US laws at all.
How does Windmill compare to Zapier in features?
Windmill offers Script and flow editor, TypeScript/Python/Go/Bash support, Scheduling, Webhooks, and 5 more features. While Zapier's ecosystem may be larger due to its market position, Windmill covers the core functionality that most teams need. The trade-off is typically between breadth of integrations (Zapier) and data sovereignty with regulatory certainty (Windmill).
Can I migrate from Zapier to Windmill?
Yes. Most European software providers, including Windmill, offer migration tools or documentation to help you transition from US-based services. Under GDPR Article 20, you have the right to data portability — meaning Zapier must provide your data in a machine-readable format. The migration process varies in complexity depending on your data volume and integrations, but for most teams it can be completed within a few days to a few weeks.
