What is it?

Valour is a community platform where each community is called a planet. A planet can include chat channels, thread feeds, wikis, voice and video calls, roles, an in-app economy, and a village view where members move around and meet. The client supports tabs, split views, and multiple open conversations at once. Apps are available in the browser, as a Mac Catalyst build, and as an Android app.

The codebase is written in C# on .NET, with a shared Blazor UI used by the browser and native hosts. The server provides HTTP APIs and SignalR connections, and bots use the same SDK and API contracts as the client. Entity Framework handles the database layer, with PostgreSQL and Redis as the backing services.

Self-hosting uses a Docker Compose bundle that includes the application, PostgreSQL, Redis, Caddy for HTTPS, and filesystem media storage. Optional federation lets a hub manage accounts and a registry while independent community nodes host planets on their own domains. Voice self-hosting uses a LiveKit overlay.

Things to know

  • Licensed under AGPL-3.0, a copyleft license that requires sharing modified source code, including for network use.
  • Self-hosting needs a public domain, inbound ports 80 and 443, and a generated DATAPROTECTION__KEK secret, since Compose will not start without it.
  • Development setup needs .NET SDK 11 preview, PostgreSQL, and Redis.
