The best alternatives to Slack

7 European alternatives · updated 1 November 2026 · How we select

Slack’s Pro plan quickly becomes expensive for growing teams, and the free tier’s 90-day message history limit pushes businesses to pay for features they rarely use. European alternatives like Stackfield offer predictable per-user pricing with full message history and EU-based hosting, removing the cost and compliance friction that often triggers a switch.

In short

Slack covers team messaging, file sharing, video calls, task management and workflow automation. European alternatives: Stackfield, Talkspirit, Wire, Nextcloud Hub and Jamespot and 2 more. By area: Stackfield, Talkspirit and Wire for team messaging; Stackfield, Talkspirit and Wire for file sharing; Stackfield, Wire and Nextcloud Hub for video calls; Stackfield for task management; Jamespot for workflow automation.
