Mattermost is a free, open-source platform for team communication, designed for organizations that require greater control over their data. It is available for Windows, macOS, Linux, Android, iOS, and as a web service.

Key Features of the Mattermost Platform

Mattermost was created in 2015 and was initially developed as an alternative to the Slack platform. Over time, it established its own identity and became one of the most powerful solutions for messaging. It is based on the idea of providing better and faster communication compared to email.

With Mattermost, teams can communicate in real time through text messages, audio and video calls, and file sharing. All messages, files, and conversations are indexed and searchable, making it easier to find information even after a long time.

The program uses channels to organize communication, reducing information overlap. For example, there can be channels for marketing, software development, customer support, etc. Within these channels, users can share images, videos, and other file formats.

Mattermost applies end-to-end encryption and offers role-based access control and permission management. It integrates with other applications such as Jira, Trello, Zoom, and Jenkins. The platform supports both public and private messaging.

Organizations can install Mattermost on their own servers to gain full control over internal team communication. There are numerous extensions that the community actively develops. Users can customize their workspace with different themes.

Use Cases of the Mattermost Platform

The developers describe Mattermost as a collaborative platform for mission-critical work, known for its flexibility and security. The main difference from other similar programs is that it is an open-source solution (developed under the MIT license), meaning it can be fully adapted to the needs of the organization using it.

Mattermost is an alternative to commercial solutions such as Slack, Discord, and MS Teams. Its availability on mobile platforms allows teams to stay connected while on the move. The web version further extends the range of devices on which this communication platform can function.

Mattermost requires technical knowledge for installation and maintenance. There are multiple versions, with the free version having limited features compared to the paid ones.

Mattermost is popular among development teams. Due to its high level of security, it is used by corporations. Schools and universities use this platform for communication between teachers and students, as well as for project management.
