In-Depth Analysis
Slack
Central hub for workplace communication and collaboration
Slack is the default team messaging tool, and its pricing reflects that dominance.
Watch out
90-day message history on Free: after 90 days, old messages become invisible (not deleted, they return if you upgrade). This is the most common upgrade trigger and feels coercive for teams that relied on older unlimited history

- +Deepest third-party integration ecosystem of any team chat tool (2,600+ apps)
- +Slack Connect eliminates email chains with external partners via shared channels
- +Powerful search across all messages, files, and connected apps from one bar
- +Workflow Builder lets non-technical users automate routine processes
Weaknesses
- -Free plan limits message history and allows only a limited number of app integrations
- -Notification overload in large workspaces, channels can become noisy without discipline
- -Pricing adds up quickly for large teams
- -No built-in project management, still requires separate tools like Asana or Jira
- -Slack AI features require higher-tier plans, not available on all plans
