Siphon is an unofficial, community-built Windows tray utility for developers who use Claude Code. It sits in the system tray and surfaces the current 5-hour session quota, the rolling weekly limit, and daily and monthly cost totals, reading from the local Claude Code data files and the OAuth usage endpoint that Claude Code itself uses for authentication.
When a session quota reaches 100%, Siphon schedules a native Windows toast notification for the exact reset time so the next usage window is not missed. If the application is closed when the reset occurs, the missed notification fires on the next launch.
An optional always-on-top floating widget keeps the key numbers visible during work, and color-coded tray icons reflect the current quota level at a glance. The interface is available in English and Brazilian Portuguese. Siphon is open source under the MIT license and is not affiliated with, endorsed by, or sponsored by Anthropic.
