Slack
Slack — Cloud messaging platform for team communication with channels, threads, apps, and a REST bot API.
Our Verdict
The incumbent team chat, loved and loathed; hard to avoid even when Teams or Lark pressure it.
Pros
- Default chat for modern knowledge work
- Huge app directory and robust bot API
- Channels, threads, and DMs well tuned
- Enterprise-grade compliance tooling
Cons
- Pricing feels punitive at scale
- Message retention limits on free plan sting
- Notifications drown less-disciplined teams
- Search across long history still weak
Best for: Tech-forward companies needing a best-in-class chat platform with a rich app ecosystem.
Not for: Microsoft-standardized orgs or teams prioritizing suite-bundled collaboration.
