Rating: 4.4 / 5 — Slack is still the best team communication tool for most businesses. The channel model is intuitive, the integrations are unrivaled (2,000+ apps), and the new workflows and huddles features have closed the gap with competitors. It's not cheap at scale, but for productivity, it earns its keep. Pro at $8.75/mo is fair for what you get.

Pricing
Slack's pricing is per-user, per-month:
- Free: 90-day message history, 10 apps/integrations, 1:1 huddles. Good for micro-teams testing the waters.
- Pro ($8.75/mo per user): Unlimited message history, unlimited apps, group huddles, guest access. The standard for most small businesses.
- Business+ ($15/mo per user): Adds SAML/SSO, 99.99% uptime SLA, compliance exports, and 24/7 support. Necessary if you have compliance requirements.
💡 Pro gets expensive at 50+ users ($437/mo). Evaluate whether you actually need unlimited history — the free plan's 90-day window is enough for many small teams.

- Excellent search that actually finds what you need
- Huddles replace internal Zoom calls
- Workflow automation reduces repetitive tasks
❌ The Bad

- Can become a productivity sink if not managed well
Verdict
🏆 Choose Slack if: Your team lives in integrations. Slack's superpower isn't messaging — it's connecting all your tools into one place. If you use a dozen SaaS tools and need them to talk to each other, nothing does it better. Teams gives Slack a run for its money on price (included with Microsoft 365), but Slack's UX and integrations are still superior.
