EU Alternatives to Slack

Slack

Slack is a cloud-based messaging and collaboration tool. It offers team chats, direct messages, and audio or video calls, while also integrating with a wide range of third-party services such as Google Drive, GitHub, and Trello. Although widely used by companies worldwide, Slack stores data primarily on US servers and is subject to US jurisdiction, raising concerns about privacy and compliance with strict EU data protection rules (GDPR). For organizations seeking stronger data sovereignty, EU-based alternatives may provide a more secure and compliant choice.
