Mattermost Secure Chat Interface

Collaboration Infrastructure

πŸ“ž

Dedicated Calls Port

Voice and video calls require special UDP port configurations that most hosts block. We pre-configure your Calls Port so you can start a team meeting instantly.

πŸ“±

Mobile Ready

Work from anywhere. Your Leapjuice server connects natively to the official Mattermost iOS & Android apps. Push notifications work out of the box.

πŸ›‘οΈ

Data Sovereignty

Stop feeding your internal strategy discussions to Salesforce (Slack) or Microsoft (Teams). Your chat logs live on your Leapjuice NVMe drive, nowhere else.

Unlimited Chat History Infinity

Unlimited History. Zero Fees.

Free Slack workspaces hide your messages after 90 days. We don't.

Leapjuice Mattermost gives you Unlimited Message History and Search. Go back 5 years and find that one file or conversation. It's your dataβ€”why should it disappear?
