# Our open-source stack

> Plauder.Party stack explained: Matrix for interoperable chat, Cinny as the client, LiveKit for voice and video — all inspectable and self-hostable.

Matrix, Cinny, and LiveKit - what each component does.


Plauder.Party builds on software you can inspect and self-host.

## Matrix

Matrix is an open standard for decentralized communication. Messages, rooms, and identities are interoperable - you are not locked to one vendor. End-to-end encryption is available for DMs and rooms.

## Cinny

Cinny is a lean Matrix client for web and desktop. Channels, DMs, and room settings in a familiar UI - without a heavy Electron shell.

## LiveKit

For voice and video we use LiveKit (WebRTC). Media runs on our EU infrastructure, separate from the Matrix homeserver.

## Custom SSO

Our own sign-in layer connects the services - currently in development. Details will follow on the blog.

**Note:** We do not claim to be “better than X.” We offer a transparent alternative for communities that care about open source and EU hosting.
