The Bottom Line

Best for

Startups, agencies, and companies not already paying for Microsoft 365 — especially teams that value messaging UX over bundled everything. For M365-standardized enterprises, Teams is the cheaper default even if users prefer Slack's day-to-day feel.

Entry price

Free plan available, paid tiers above

Biggest pro

Intuitive interface with low learning curve, most teams adopt it within days

Biggest con

Free plan limits message history and allows only a limited number of app integrations

TL;DR - Slack

Channel-based messaging platform with 2,600+ integrations, huddles, Canvas docs, and workflow automation
Free plan covers basics (90-day history, 10 apps); paid plans start at $7.25/user/month with unlimited history
Best for distributed teams needing deep app integrations, less ideal if you need built-in project management

What Users Say About Slack

Slack's 2026 story is about AI integration. Users (42M daily actives) praise the AI features bundled into all paid plans since mid-2025 — thread summaries, meeting recap, search improvements. The persistent complaint: Microsoft Teams' free bundling with M365 is still winning on price, even as Slack now beats Teams on AI cost-per-user ($7.25 Pro vs $18+/mo for Teams + Copilot).

Highlights

Snappier messaging UX than Teams — still the best daily-driver feel
Slack AI bundled in all paid plans since mid-2025 — no $10/user/mo add-on
Slack Connect shares channels with external partners — essential for agencies and client work
Canvas (collaborative docs in channels) matured beyond Teams' Loop components
Semantic search (Pro+) actually finds what you meant, not just keyword matches

Limitations

Pro at $8.75/user/mo is pricey vs Teams bundled free with M365
Enterprise Grid pricing is custom and frequently $15-25+/user/mo
Huddles and video quality still trail Zoom and Google Meet
Some enterprise compliance controls lag behind Teams
File storage limits (5GB Free, 10GB Pro) are stingier than Teams + OneDrive

Best for: Startups, agencies, and companies not already paying for Microsoft 365 — especially teams that value messaging UX over bundled everything. For M365-standardized enterprises, Teams is the cheaper default even if users prefer Slack's day-to-day feel.

Slack Connect enables secure communication with external partners and clients. The platform integrates with over 2,600 apps including Google Workspace, Salesforce CRM, Jira, and GitHub. Slack AI provides channel summaries, daily recaps, and thread catch-ups. Used by organizations from startups to Fortune 100 companies, the platform processes a high volume of messages daily, with a significant number of Slack Connect users collaborating across organizations weekly.
