DEV-TOP · horizontalOur take
The default choice for team chat for most small-to-mid teams — the free tier is genuinely usable for very small teams, and the ecosystem of integrations is unmatched, but per-seat costs add up fast for larger headcounts.
Choose this if...
- Teams already living in a messaging-first workflow who want the deepest app-integration ecosystem
- Small teams that can operate within the 90-day history cap on Free
Look elsewhere if...
- You want video conferencing as a primary feature rather than an add-on — huddles are lighter-weight than Zoom/Meet
- You're cost-sensitive at scale — per-seat pricing on Pro/Business+ adds up quickly for larger teams

Free tier reality
Free plan caps message history at 90 days and restricts calling to 1:1 huddles only — no group voice/video meetings. App integrations are capped at 10. Pro removes both caps but is still 1:1-meeting-limited-free; Business+ is the first tier with compliance features. Slack's own pricing page also showed a limited-time 50% introductory discount on Pro/Business+ at time of check — the figures recorded here are the standard (non-promo) list prices.
