European Alternative to Slack

🇺🇸Salesforce · US-based

Slack is a messaging application developed by Salesforce, designed to facilitate communication and collaboration within teams and organizations.

Slack is known for its customizable workflow automation and AI-powered message suggestions, which aim to enhance productivity and streamline communication. The application supports cross-application integrations, allowing users to connect with other tools they use daily. Additionally, Slack provides searchable message history and secure guest access for external partners, making it suitable for both internal and external communications. The primary users of Slack include businesses, project teams, and organizations looking for a centralized communication platform. It is important to note that Slack is a US-based product, and user data is stored in the United States, subject to US data laws such as the CLOUD Act and FISA 702. Slack operates on a freemium pricing model, offering basic features for free with additional functionalities available through paid plans.
