Slack Alternatives
Slack
Slack is a unified communication platform built with an optimized workflow to keep modern teams focused and productive. A familiar chat interface facilitates discussions while advanced features are easily exposed based on context. Hover over a message to see more options such as emoji reactions, sharing and pinning features and more. A navigation bar provides easy access to key features including a powerful search to find important discussions, files and more.
Conversations are organized across dedicated Channels, neatly arranged in a responsive sidebar with collapsible sections. These Channels are highly configurable and allow for flexibility in working with various teams but can also be shared externally, making it easy to hold discussions with partners and clients.
