There is no single best Slack replacement for every team. Microsoft Teams and Google Chat are natural fits when you already use Microsoft 365 or Google Workspace; Mattermost suits organizations that prioritize deployment control; and Twist, Zulip, and Discord offer distinct communication styles. Start with your existing tools, data-control requirements, and need for asynchronous chat, voice, or video—not a universal ranking.
Compare alternatives by how your team works
Slack’s own comparison pages frame alternatives around differences in integrations, security, communication features, and audience. Those descriptions and integration counts are vendor-published, not independent rankings. Use them to build a shortlist, then verify critical capabilities with each provider.
| Option | Potential fit | What to verify |
|---|---|---|
| Microsoft Teams | Organizations centered on Microsoft 365 and teams seeking chat alongside meetings and collaboration. | Current Microsoft 365 integration, meeting features, administration controls, and the plan that includes the capabilities you require. |
| Google Chat | Teams already working in Google Workspace, with Chat alongside Gmail, Drive, and Meet. | Workspace plan requirements, administration, and whether its communication features fit your workflow. |
| Mattermost | Organizations prioritizing infrastructure or deployment control. | Whether self-hosted, private-cloud, or managed-cloud deployment meets your technical and compliance needs—and who will maintain it. |
| Twist | Teams that favor asynchronous communication. | Whether its current features and integrations cover the workflows you need; Slack’s comparison lists no native voice or video. |
| Zulip | Distributed teams that want conversations organized in threads. | Whether its current calling options and integrations meet your needs; Slack’s comparison lists no native voice or video. |
| Discord | Groups that value community-oriented communication and voice/video. | Whether its administration, identity, and governance capabilities are appropriate for workplace use. |
| Rocket.Chat | Teams exploring open-source flexibility and security-focused positioning. | Deployment, security, and administration details in Rocket.Chat’s own documentation. |
| Pumble, Wire, or Flock | Additional candidates described by Slack as budget-oriented, secure-enterprise, or cross-functional options, respectively. | Current plan limits and the specific features behind those descriptions. |
Which Slack alternative fits your situation?
Choose Microsoft Teams for a Microsoft-centered workplace
Slack’s comparison positions Teams for Microsoft-centric organizations and unified collaboration. TechRadar’s 2026 description also cites Office 365 integration and features such as screen sharing, recording, breakout rooms, live captions, and transcription. Those third-party descriptions are not a substitute for checking Microsoft’s current product and plan documentation.
Choose Google Chat if your team already uses Google Workspace
Slack’s comparison places Google Chat alongside Google Workspace tools including Drive, Gmail, and Meet. The practical question is whether using Chat within that environment serves your team better than adding a separate communication platform; check the Workspace edition and controls your organization needs.

Consider Mattermost when deployment control matters
Slack’s June 2026 comparison describes Mattermost as open-source and available as self-hosted, private-cloud, or managed cloud, and notes playbooks for repeatable workflows. Because Slack competes in this category, treat these as claims to validate with Mattermost. Self-hosting can increase infrastructure control, but your organization takes on operating and maintaining that infrastructure.
Consider Twist or Zulip for different asynchronous patterns
Slack describes Twist as async-focused and Zulip as organized around threaded communication. Its comparison table lists neither as having native voice or video. Confirm current product capabilities directly, especially if calls are central to your team’s work.

Consider Discord for community-style communication
Slack’s comparison describes Discord as community-focused with voice and video. That can be appealing for live interaction, but community-oriented features alone do not establish that a product meets workplace requirements for administration, identity, or governance.
Keep Rocket.Chat, Pumble, Wire, and Flock on a verification list
Slack’s alternatives table characterizes Rocket.Chat around open-source flexibility and security, Pumble around budget, Wire around secure enterprise communication, and Flock around cross-functional communication. These are vendor-comparison labels, not independent evaluations. Check each provider’s current documentation against your requirements before treating a label as a deciding feature.

Check capabilities, not just the product name
“Team chat” does not guarantee identical collaboration. Before choosing, write down what the team actually uses and distinguish essential features from preferences:
- Communication: channels, threads, asynchronous updates, voice, video, and meetings.
- Connected tools: the integrations your team depends on, including who supports and maintains them.
- Administration and security: access controls, identity management, compliance needs, and data governance. Vendor descriptions are not independent certification evidence.
- Deployment: hosted service, private cloud, or self-hosted operation, including responsibility for upgrades and infrastructure.
- Cost: the plans and billing terms needed in your region, plus administration, migration, and retraining effort.
Slack says its Marketplace has over 2,600 apps; that is a vendor-published figure, not an independently audited count or evidence that another platform’s integration total is directly comparable. Focus on whether the alternatives support the specific connections your team relies on.

Before switching, verify cost and migration requirements
Do not assume that replacing Slack will reduce costs. A reliable comparison requires current official plan information for your region, billing cadence, user thresholds, feature gates, and taxes. Include the work of setup, administration, and onboarding when assessing the total effort.
Migration compatibility and effort depend on your existing workspace and the destination product. The cited comparisons do not establish supported Slack export or import formats, integration-migration coverage, effects on retention, or likely downtime. Confirm these details with both vendors before scheduling a change.

- Confirm how identity provisioning and account administration will work in the new platform.
- Ask both providers which data and integrations can be migrated, what cannot, and whether migration affects retention or availability.
- Compare the actual plans your users need, including billing terms and applicable taxes.
- Plan user onboarding and allow time to test essential workflows before committing to a full transition.
