PrivMX Fusion · legacy

The suite that
started it all.

PrivMX Fusion is the end-to-end encrypted team workspace that PrivMX grew from. It is still available for self-hosting – and today PrivMX has moved on to a developer platform and new products.

PrivMX Fusion

An open-source, self-hosted collaboration suite: one workspace for everything a team does every day, with all data end-to-end encrypted – not only messages.

  • ChatsConversations and video calls with your team.
  • FilesDocuments and files, encrypted before they leave your device.
  • TasksTo-do lists and task tracking.
  • CalendarShared calendars for the team.

Two parts. The Team Server is a Node.js, zero-knowledge server for Debian-based Linux (at least 2 GB RAM), installable from a .deb package or with Docker. The Desktop client is an Electron app for Windows, macOS and Linux.

Activation. On first start the server generates an activation token. You paste it into the desktop app and create the first account – the Team Keeper.

Video calls need the optional PrivMX Video Server installed next to the Team Server.
