About:
Slack is a proprietary business communication platform developed by American software company Slack Technologies. Slack offers many IRC-style features, including persistent chat rooms (channels) organized by topic, private groups, and direct messaging.
Key Features:
Slack offers many IRC-style features, including persistent chat rooms (channels) organized by topic, private groups, and direct messaging. Content, including files, conversations, and people, is all searchable within Slack. Users can add emoji buttons to their messages, on which other users can then click to express their reactions to messages.
- Slack’s free plan allows only the 10,000 most recent messages to be viewed and searched.
- Teams – Slack teams allow communities, groups, or teams to join a “workspace” via a specific URL or invitation sent by a team admin or owner. Although Slack was developed for professional and organizational communication, it has been adopted as a community platform, replacing message boards or social media groups.
- Messaging – Public channels allow team members to communicate without the use of email or group SMS (texting). Public channels are open to everyone in the workspace.
- Private channels – allow for private conversation between smaller sub-groups. These private channels can be used to organize large teams.
- Direct messages – allow users to send private messages to specific users rather than a group of people. Direct messages can include up to nine people. Once started, a direct message group can be converted into a private channel.
- Integrations – Slack integrates with many third-party services and supports community-built integrations, including Google Drive, Trello, Dropbox, Box, Heroku, IBM Bluemix, Crashlytics, GitHub, Runscope, Zendesk and Zapier. In December 2015, Slack launched their software application (“app”) directory, consisting of over 150 integrations that users can install.
- In March 2018, Slack announced a partnership with financial and human capital management firm Workday. This integration allows Workday customers to access Workday features directly from the Slack interface.
- API – Slack provides an application programming interface (API) for users to create applications and automate processes, such as sending automatic notifications based on human input, sending alerts on specified conditions, and automatically creating internal support tickets. Slack’s API has been noted for its compatibility with many types of applications, frameworks, and services.
