Show HN: Tokenmaxx – CLI that merges usage across Claude Code and Codex accounts

Tokenmaxx is a CLI from RubricLab that merges usage data across Claude Code and Codex accounts. It appeared as a Show HN on Hacker News, with the repo at github.com/RubricLab/tokenmaxx and the discussion at news.ycombinator.com/item?id=48995775. At listing time it had 3 points and 0 comments.

The product is a command-line tool, not a hosted dashboard or IDE plugin. Its stated job is to combine usage across Claude Code and Codex so operators see one view instead of checking each product’s own accounting. Mechanics beyond that merge role are not specified in the listing.

Engineers who run both Claude Code and Codex often track spend and limits in separate UIs. A single CLI that merges that usage cuts context switching when budgeting sessions, checking headroom before long runs, or reconciling team cost across the two stacks.

The Show HN framing puts Tokenmaxx next to other small utilities that stitch AI coding tools together rather than replace them. Claude Code and Codex each ship their own usage surfaces; a third-party merge layer sits in the gap for people who refuse to standardize on one vendor. Early traction is thin: 3 points and no comments yet, so demand is unproven on HN alone.

Practical next steps: install from the RubricLab GitHub repo, run it against real Claude Code and Codex credentials, and confirm the merged totals match each product’s native usage views. Watch whether the project documents supported auth methods, export formats, and how it handles multi-account setups as the Show HN thread (if it grows) and the repo evolve.
