About Slack

Slack is a team messaging platform organised around channels, available on web, Windows, Mac, iOS, and Android, designed to replace internal email for professional teams. Channels can be public or private, and messages are fully searchable. Slack's 2,500+ app integrations connect it directly to GitHub pull requests, Jira issues, Google Drive files, PagerDuty alerts, and hundreds of other developer and business tools. Huddles provide low-friction audio calls without scheduling a meeting. The free tier gives 90 days of message history and 10 active integrations. Paid plans unlock full message history, unlimited integrations, and Slack AI for summarising channel threads. It is the standard team communication tool at software companies of all sizes.
