Frequently asked questions

What is the main difference between Stackfield and Trello?

Stackfield is a German tool with EU-only hosting, end-to-end encryption and compliance certifications like ISO 27001 and BSI C5. Trello is US-based, hosted on AWS and subject to the CLOUD Act, with a focus on lightweight Kanban boards.

Where is my data hosted with Stackfield and Trello?

Stackfield hosts all data exclusively in German data centers. Trello stores data on US-based AWS infrastructure, which may involve transfers outside the EU.

Which tool is better for GDPR compliance?

Stackfield is the stronger choice for GDPR compliance due to its EU-only hosting, end-to-end encryption and German jurisdiction. Trello’s US hosting and CLOUD Act exposure create compliance friction for EU businesses.

Which is better for a small team?

Trello suits freelancers or very small teams that prioritise simplicity and quick onboarding. Stackfield is better for teams of five or more, especially those needing integrated tools and compliance features.

Which is better for a company with works-council or strict data-protection requirements?

Stackfield is the clear choice. It offers EU-only hosting, end-to-end encryption and certifications like ISO 27001 and BSI C5, which address works-council and regulatory demands in Germany and the EU.

Do Stackfield and Trello offer Kanban boards?

Both offer Kanban boards. Stackfield adds Gantt charts, integrated chat, video calls and file management, while Trello focuses on a lightweight Kanban experience with Power-Ups for additional functionality.

How do Stackfield and Trello compare on integrations?

Trello has a vast ecosystem of Power-Ups for integrations. Stackfield offers native integrations with common tools but focuses more on built-in features like chat and video calls, reducing the need for third-party add-ons.

Can I migrate from Trello to Stackfield?

Yes. Trello exports boards as JSON or CSV, which Stackfield can import. However, custom fields, automations and some metadata will not transfer and must be rebuilt manually.
