Product

What it currently does

Horizon is a KDE Plasma application for Linux. It tracks remaining quotas for AI coding tools you already use. Currently named services are Codex, Cursor and StepFun.

The compact panel shows one remaining percentage: the lowest among enabled providers. The popup shows per-provider plan, meters, reset times, and stale, auth or error labels. Providers can be turned on or off in widget settings.

Quota APIs for these tools are unofficial and can break when a provider changes them. Horizon does not implement provider login or OAuth.
