Open-source alternative to Slack for internal team communication.
Mattermost is a collaborative messaging platform designed for professional teams. Themed channels, private messaging, integrations, and notifications make it a comprehensive tool for internal communication.
Hosted on your server, it guarantees confidentiality and sovereignty of exchanges.
Test Mattermost for up to 7 days. If the tool does not meet your expectations, send a cancellation request during this period, and you will receive a full refund, no questions asked (offer limited to one application per person).
No worries. Explain your requirements in the registration form, along with the approximate number of users, and I will get back to you with advice. If the solution is not suitable for your situation, I will let you know. You can also call me directly to discuss it in person, or book a video call at a time that suits you.
Yes, you can test an application for 7 days with no obligation. An instance will be created for you, and if at the end of the trial you do not wish to continue, you will receive a refund within a few days. The data will be completely deleted.
Of course, you can upgrade or downgrade your plan at any time. If you pay monthly, your request must be made before your next invoice is renewed. For annual commitments, you can also make the request during the year, prorated for the months already used. If you downgrade your plan, you will need to ensure that your used disk space does not exceed the new limit.
