Slack
Slack organizes team communication into channels with 2,000+ integrations. Learn why teams use it, who it's best for, and alternatives.
Why this tool?
The problem
Email threads get buried, decisions are hard to find later, and pinging colleagues across tools creates fragmented communication.
The old way
Email chains for async discussion, Zoom for everything synchronous, and no searchable record of why decisions were made.
The better way
Slack channels keep conversations organized by project or topic, threaded replies prevent noise, and search surfaces any decision instantly.
What makes it stand out
The integration ecosystem is unmatched—nearly every developer, marketing, and operations tool has a native Slack integration.
Tradeoffs to consider
Can become noisy without disciplined channel hygiene; free plan limits message history to 90 days; costs scale quickly for large teams.
Who it is for
When not to use it
For very small teams (1–3 people), free plans with limited message history may frustrate. Microsoft Teams is stronger for Microsoft 365 shops.
