Best for Teams that need developer tools with EU data residency Teams already invested in the Prefect ecosystem

Choose Kestra 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 Prefect if…

  • You depend on integrations only available in the Prefect ecosystem
  • Your organisation has no EU data-residency constraints
  • Migration costs outweigh the jurisdiction benefits for now

Why choose Kestra over Prefect?

The decisive argument is data jurisdiction. Prefect 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.

Kestra 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.

Frequently asked questions

Is Kestra a good alternative to Prefect?
Yes. Kestra is one of the top-ranked European alternatives to Prefect in our directory, covering the same developer tools use case. It is headquartered in France, keeping your data under EU law by default.
What's the main difference between Kestra and Prefect?
The biggest difference is jurisdiction: Kestra is based in France and operates under GDPR and EU data-protection law, while Prefect is headquartered in US and may transfer data outside the EU. For regulated industries or organisations following Schrems II guidance, this difference is decisive.
Is Kestra GDPR-compliant?
Kestra is a European company based in France, so GDPR compliance is the default operating model rather than a bolt-on. No transfer impact assessment is required for EU customers, unlike when using Prefect.
How do I migrate from Prefect to Kestra?
Start by exporting your data from Prefect (most providers offer an export in their settings). Then import into Kestra using its native import tool or migration guide. Running both in parallel for a week catches any feature or workflow gaps before you fully switch.
