Slack
FreeA workplace messaging platform built around channels, huddles and app integrations, owned by Salesforce.
About Slack
Slack is a business messaging platform that organises conversation into channels by team, project or topic. It adds direct messages, threads, audio and video huddles, file sharing, search, and a large directory of integrations and workflow automations.
It runs on Windows, macOS, Linux, Android, iOS and in a browser. Individuals can start a workspace on a free plan with limits such as message history, and paid plans add features for larger organisations including admin controls and expanded history. Specific pricing is not in the supplied data, so check the official pricing page.
Slack suits teams that want a searchable, organised alternative to email for daily collaboration, especially when they connect it to tools such as calendars, ticketing and code hosting. It requires an account tied to a workspace, and heavy use of notifications can become noisy without channel discipline. Google Play lists more than 50 million downloads, and the iOS app has about 53,000 ratings.
Agree on channel naming and notification rules early. The free plan limits how much history you can view.
