Are Open Source tools from EU companies GDPR-compliant?
EU-headquartered Open Source providers are subject to the GDPR by default. The Open Source startups on this page are based from Germany, France, and Netherlands; whether a given company is outside the US CLOUD Act depends on its ownership and hosting, which EU Alts checks per listing.
How do I switch to a GDPR-compliant Open Source alternative?
Start by identifying which EU-based Open Source tools match your feature requirements from the list above. Most EU providers offer free trials and data migration guides to help you move from US-based incumbents. For a Open Source switch specifically, check what data export formats your current tool supports and whether the EU alternative offers an importer.
