What is Moss?
Moss is a runtime for composable peer-to-peer collaboration. You install it like any other desktop app, and then use it to create groups — each group is a private network where you and the people you invite can install and compose collaboration tools to meet your needs.
There are no central servers. There are no accounts. There is no company holding your data. A group is just the people in it, running Moss, connecting directly to each other.
The short version
- Moss is a desktop app. It runs on macOS, Windows, and Linux.
- Groups are private peer-to-peer networks. You make one, invite others, and the group exists between you.
- Tools are what you use inside a group. Chat, documents, task boards, calendars — pick the ones you want. Add more later.
- Tools can link to each other. A chat message can point to a document. A task card can reference a calendar event. This is the Weave Interaction Pattern.
What Moss is not
- Not a chat app. Not a docs app. Not any one thing. It's a container for the tools you choose.
- Not a cloud service. Your data lives on the devices of group members.
- Not a replacement for everything overnight. It's an open standard + reference app for what collaboration can look like when groups own their own social space.
