Slack vs Teams vs Discord — Attribute Category Vocabulary
Taxonomy of attribute categories used to classify comparison data for Slack vs Teams vs Discord.
Can I use Discord for business communications?
While Discord can technically be used for business, it lacks enterprise security certifications (HIPAA, FedRAMP), has no message search, and no compliance audit trails. It's best suited for informal teams, open-source projects, or communities rather than regulated industries or formal corporate communications.
Is Teams really free if I have Microsoft 365?
Yes, Teams is included in all Microsoft 365 subscriptions at no additional cost. However, the standalone Teams free plan has limitations: 1-on-1 video calls only, 60-minute group meeting limit, and no advanced features. Standalone Teams Essentials costs $6/user/month.
Slack's premium pricing ($8.75/user/month) reflects its specialized focus on searchability, integrations, and workflow automation. Teams offers lower standalone pricing ($6/month) because many users access it free through Microsoft 365 bundles. For pure ROI, the choice depends on whether you need Slack's superior search and integrations.
Which platform is best for gaming teams?
Discord dominates gaming with superior voice quality, low-latency audio, free access, and a gaming-native community. Slack and Teams are optimized for business, not gaming. Discord's servers and channels are intuitive for raid groups, esports teams, and gaming communities.
Can I migrate from Slack to Teams or Discord?
Yes, data export is possible from Slack (via third-party tools or API), but Teams and Discord have limited import capabilities. Migration is labor-intensive and often requires manual effort. Most organizations use parallel systems during transition rather than pure migration.
