    Our take

    Understanding Slack.

    Slack is professional messaging for communicating with clients and partners. Starting at €6.28/month. Built for managers and IT directors and SaaS founders.

    Estimated time saving: 3h/month.

    Keep it if: you collaborate with clients who use Slack or you manage a small team (2-5 people). Skip it if: you are a 100% solo freelancer (emails are enough) or your clients do not use Slack. As soon as you collaborate regularly with a team or clients who use Slack. Free alternative: discord.

    Practical uses

    • Team chatSearchable history and CRM/GitHub integrations.
    • Automated workflows notifying on GitHub bugs or Salesforce updates.
    • AI analysis summarizing async discussions for quick team alignment.

    Pros and cons

    What Slack does especially well — and the limits to anticipate.

    Pros

    • Unlimited searchable message history (all paid plans).
    • 1000+ native integrations or via Zapier/webhooks.
    • No-code workflows and automations.
    • Slack AI for conversation summaries and analysis.

    Cons

    • Free plan limited (90-day history, 10 integrations max).
    • Per-active-user cost becomes substantial for large teams.
    • No AI on Free/Pro plans (Business+ minimum required).

    Slack: when it makes sense.

    Slack suits tech teams prioritizing asynchronous chat and integrations; for video conferencing focus or tight budget, Microsoft Teams or Discord fit better.

    Keep if

    Your team prioritizes asynchronous communication and searchable history.. You need 1000+ integrations with existing tools.

    Slack becomes worthwhile when
    • You use it at least once a week
    • The monthly cost (€6) is small next to the time it saves you

    Challenge if

    You prioritize high-fidelity video conferencing (consider Teams/Zoom).. Limited budget favors free chat alternatives (Discord, Mattermost).

    Slack becomes too expensive when
    • You use it less than once a month
    • discord (free) already covers the essentials for occasional use

    Our verdict on Slack.

    Why this verdict

    Decent

    Slack is fairly easy to replace with an alternative, a free tier to test before paying, clearly documented use cases.
