Feature-by-Feature Breakdown
Data Privacy & Compliance
Stackfield’s core selling point is EU-based hosting and GDPR-focused infrastructure, with end-to-end encryption for chat - a genuine advantage for European teams with strict compliance requirements who want a cloud-only solution.
Worklenz offers a different path to data control: full open-source self-hosting, so you control infrastructure location entirely rather than relying on a vendor’s EU hosting commitment.
Winner: Depends on approach - Stackfield for EU-hosted cloud without self-hosting effort, Worklenz for teams wanting to control their own infrastructure.
Team Chat & Communication
Stackfield integrates team chat and video conferencing as core, well-built features alongside project management.
Worklenz offers basic collaboration (comments, mentions) but doesn’t include a full chat/video system.
Winner: Stackfield, for teams wanting integrated chat and video without a separate tool.
Task & Project Management

Worklenz offers comparable project management depth - boards, lists, subtasks - with resourcing as a more central feature.
Winner: Tie, both cover core PM needs well.

Stackfield doesn’t emphasize dedicated resource/workload views as a core feature.
Worklenz provides team-wide utilization visibility as standard.

Worklenz is genuinely open source (AGPL-3.0) and self-hostable for free.
Winner: Worklenz, for teams wanting actual infrastructure control rather than trusting a vendor’s hosting location.

Frequently Asked Questions
Is Stackfield GDPR compliant?
Stackfield markets itself around EU hosting and GDPR-focused infrastructure, which is a real differentiator for European teams that want compliance without managing their own servers.
Is open-source self-hosting more private than Stackfield’s EU hosting?
It depends on your threat model - self-hosting (Worklenz) gives you full control over where data lives and who can access the infrastructure, while Stackfield’s EU hosting relies on trusting their compliance commitments rather than running your own servers.
Does Stackfield have a minimum team size?
Yes - most plans require a minimum of 5 users, so smaller teams pay for unused seats.
Does Worklenz include team chat like Stackfield?
Worklenz offers basic comments and mentions but not a full chat/video conferencing system. If integrated team chat is a priority, Stackfield’s bundled approach may suit you better.
Final Verdict
If you’re an EU-based team that wants GDPR-focused cloud hosting with integrated chat, without managing your own infrastructure, Stackfield is a solid choice. If you want genuine open-source control over your data - with no seat minimums and resourcing built in - Worklenz offers a more direct path to that control.
