2015. Mattermost - open-source, on-premise Slack-alternative



GitLab, the provider of git repository management, has joined forces with SpinPunch, a YC alumni, to introduce Mattermost, an open-source messaging app designed for on-premises deployment (similar to Slack). Many large organizations opt for on-premises software hosting due to security, scalability, and control reasons. However, Slack lacks an on-premises version. Mattermost was developed as a team communication platform that enables users to exchange messages and files across multiple channels, receive notifications and alerts, and search message history on both PCs and smartphones. Users can utilize hashtags to organize messages and threads, customize team-specific color themes, and archive important communications for future reference. In summary, Mattermost provides a more streamlined and efficient approach for remote teams to collaborate and communicate compared to traditional email, which is starting to feel outdated in comparison.
