15 Alternatives

Microsoft

Enterprise Collaboration SuiteEnterprise

Microsoft Teams competes with Slack in enterprise communication by bundling chat, video, and file sharing directly into the Microsoft 365 ecosystem. While Slack focuses on a best-of-breed, flexible user experience, Teams offers a distinct advantage for organizations already invested in the Microsoft stack, providing seamless integration with SharePoint and Outlook.

Mattermost

Open Source CollaborationMid Market

Mattermost competes with Slack by providing a self-hosted, open-source alternative for teams requiring strict data sovereignty. While Slack operates as a cloud-native SaaS, Mattermost allows organizations to maintain full control over their infrastructure. This is a key differentiator for highly regulated industries that cannot rely on public cloud storage.

Discord

Community Communication PlatformMid Market

Discord competes with Slack in real-time messaging and voice channels, particularly for agile teams and creative communities. Unlike Slack’s structured, thread-heavy workspace, Discord offers a more fluid, low-friction environment for spontaneous voice interaction. Buyers often choose Discord for its superior audio quality and lack of restrictive message history paywalls.

Rocket.Chat

Open Source Communication PlatformMid Market

Rocket.Chat competes with Slack in the open-source messaging space, offering high levels of customization and white-labeling capabilities. Unlike Slack’s rigid interface, Rocket.Chat allows developers to modify the platform’s source code to fit specific workflows. It is the preferred choice for companies needing deep integration with custom internal tools and private servers.

Chanty

Team Chat and Task ManagementSMB

Chanty competes with Slack by combining team chat with integrated task management features at a lower price point. While Slack relies on external integrations for project tracking, Chanty includes these capabilities natively. This makes it a compelling alternative for budget-conscious teams looking to consolidate their communication and task tracking tools.

Flock

Business Messaging PlatformMid Market

Flock competes with Slack by offering a more streamlined, lightweight communication experience focused on built-in productivity tools like task management and polls. Unlike Slack’s complex, app-heavy ecosystem, Flock provides a simpler, all-in-one interface.
