Spacebar is split into two components: spacebar (front-end), and spacebar-daemon (backend-daemon).

The background daemon, which is configured to autostart, has the following responsibilities:

• Handles the sending and receiving of messages.
• Saves messages to the database.
• Creates notifications when a new message arrives.

spacebar-daemon exposes its API in D-Bus under the service name org.kde.spacebar.Daemon. Front-end applications like spacebar depend on it for messaging functionality. It manages incoming messages and notifications in the background without needing a front-end app running.

A front-end app for spacebar-daemon written in Kirigami.
