    Reviews

    Field Value
    G2 4.5/5​ (~38,100–38,200 verified, Winter 2026) — primary B2B star; ease 4.4, features 4.4, value 4.2, support 4.2; praise channels+integrations+onboarding, gripes cost-at-scale + notification overload + 1 GB file cap
    Capterra 4.7/5​ (~24,100–24,200) — secondary B2B; ease 4.6, features 4.6, value 4.5, support 4.4
    Trustpilot 2.8/5​ (~296) — consumer/billing/cancel friction, NOT core product quality; exclude from B2B avg, report as consumer signal only
    TrustRadius Aligns G2 (~4.5 band) low-n auxiliary
    Product Hunt Launch-era 4.x, not reweighted
    Editorial Softbliq 2026, AISOtools — feature confirm; G2 ranked Slack #5 Best Software Winter 2026
    Praise Channel model still best-in-class, 2,600+ integrations unmatched, Canvas+Huddles kill app-switching, Slack AI recaps genuinely save time, MCP server ahead of Teams/Google Chat, Salesforce CRM depth native
    Gripes $8.75×25 users steeper than Teams-bundled-with-M365, notification fatigue without discipline, 1 GB/file cap hurts design/video, Free 90-day history unusable long-term, Enterprise+ upgrade irreversible, mobile push misses mentions occasionally, no native Outlook/M365 calendar

    Access

    Field Value
    Web App https://app.slack.com — browser + desktop (Win/Mac) + iOS/Android native
    API Web API (classic + Bolt/SDKs: Node/Python/Java/Go), RTM retired, Socket Mode, Workflow Builder, MCP server GA Feb 2026 (remote, OAuth, https://mcp.slack.com/mcp)​ for Claude/Cursor/GPT/Perplexity, Real-Time Search API GA 2026, 6+ SDKs, CLI slack, Slackbot MCP client (reverse direction)
    Integrations 2,600+ Marketplace: GitHub/GitLab/Jira/Notion/Figma/Zoom/Google Workspace/Microsoft 365(add-in)/Salesforce/HubSpot/Zendesk/Asana/Linear/Tableau; Zapier/Make via app
    Admin Workspace + Enterprise Grid orgs, SAML/SCIM/EMM, audit logs, EKM add-on
    Self-host None (Slack cloud only, US/EU data residency options)

    Best For

    Field Value
    Audience 1 Remote/distributed SaaS/tech teams (10–1,000) using async channel-first comms + GitHub/Notion/Jira/Liner stack
    Audience 2 Orgs already on Salesforce wanting CRM records/alerts/Agentforce inside chat
    Audience 3 Agentic devs wiring Claude/Cursor MCP to search channels / draft messages / update canvases without leaving IDE
    Audience 4 Cross-company vendor/client collab via Slack Connect shared channels
    Audience 5 SMBs wanting Workflow Builder to replace light Zapier internals

    Not For

    Field Value
    Exclude 1 Teams deep in Microsoft 365 — Teams is bundled, double-paying for Slack seats rarely justified
    Exclude 2 China-based teams — access latency + weak CN-language/support (Feishu/DingTalk/WeCom fit better)
    Exclude 3 1–3 person micro-teams — WhatsApp/WeChat/Discord enough, Slack value is channel-scale
    Exclude 4 Community/creator discords — Discord voice/bot economy beats Slack there
    Exclude 5 Cost-sensitive startups refusing $8.75×seats when free tier’s 90-day history truncates institutional memory

    Competitors

    Field Value
    Microsoft Teams M365-bundled, stronger enterprise/Outlook/Office native, weaker third-party integration breadth, no MCP server as of 2026-08
    Google Chat Workspace-bundled, lighter, weaker app marketplace, no advanced AI agent story
    Discord Community/voice/bot-first, not B2B async work, no SAML/SCIM/DLP
    Zoom Team Chat Meeting-centric, chat secondary, tiny integration ecosystem
    Mattermost / Rocket.Chat Self-hosted open-source, regulated-env fallback, weaker UX/AI
    Webex Connect / RingCentral Comms-first, not developer-platform-first
