Overview
Slack is a messaging and collaboration platform for teams, owned by Salesforce. It is available on the web and as apps for Windows, macOS, Linux, Android and iOS.
Work in Slack is organised into a workspace with channels for projects, teams or topics, which keeps conversations easier to follow than long email threads. Members can send direct messages, share files, start audio and video huddles, and search past conversations. Slack connects with thousands of other apps and services through integrations and automated workflows. The free plan lets small teams get started but has limits, such as on how much message history is available; paid plans unlock full history, more integrations and administration features.
Slack is popular with technology companies, startups, remote teams and community projects. Administrators should configure security settings such as two-factor authentication and guest access. Download Slack from slack.com or official app stores.
