Why it stands out
Seat count is the main lever—guests and multi-workspace Grid change the model entirely. Export and e-discovery live on enterprise tracks.
Tool profile
Team messaging platform for channels, direct messages, workflows, and workplace collaboration.
Engineering incident rooms and deploy notifications
Slack is team messaging with channels, huddles, workflows, and a massive app directory for devops and business integrations.
Slack's US pricing page currently shows Pro at $8.75 per active user per month billed monthly or $7.25 billed annually, Business+ at $18 per active user per month billed monthly or $15 billed annually, and Enterprise Grid through sales. Free remains the permanent entry tier with history and capability limits, while AI and admin features move up the paid plan ladder.
Because Salesforce-owned Slack localizes pricing by country and sometimes runs promotions, verify slack.com/pricing in your billing region before treating the public list price as a final forecast.
