A local command-line tool that compares Claude Code and Codex usage with the plans their vendors sell.

Landing page captured for the 2026-09-10 issue.

Field notes

The command reads local session logs and uses ccusage in offline mode to produce separate provider blocks for Claude Code and Codex. Its documented output covers the current session, the day, and month to date, then compares list-equivalent usage with every plan it has recorded. Plan data is stored in ~/.decadra/plans.json, with prices described as hand-maintained; the site identifies the displayed dollar figures as examples rather than live measurements.
