Why it exists

Everything you need to stay under the limit

Built to answer one question at a glance — how much Codex you have left, everywhere — without logging in and out of account after account.

Every account, side by side

Session and weekly limits for all your Codex accounts on one screen. A single glance tells you where everything stands.

Alerts when it matters

Browser push notifications for resets and high usage. Scheduled checks run about every five minutes, so alerts can arrive within a few minutes of a change.

Private by design

Your Codex credential is encrypted in a private vault, never returned to the browser, and decrypted server-side only for usage checks and renewal.

Open source or hosted

Self-host the whole thing for free, or sign in with Google and use the hosted version without managing a server. Same dashboard either way.
