Coming soon. The Leaderboard tab arrives in the next release of the extension, and that is how you join. Until it ships, the board shows early testers only.

Ranked by API-equivalent cost from real local usage, measured by the Claude Code and Codex Assist extension.

## How ranking works

* Numbers come from daily usage rollups the extension builds from local Claude Code and Codex session logs.
* Cost is API-equivalent: tokens priced at each model's public list price. On a subscription it is what the usage would cost at API rates, not what you paid.
* Server-side checks recompute cost from the token counts and hold back implausible days. The top of each board is reviewed by hand, and reviewed profiles carry a verified mark.

## What is shared

Per day and per model: token counts, API-equivalent cost, request count, active minutes and turn count. Project names, file paths, prompts and code never leave your machine. You choose to appear under a username, as an anonymous entry, or not at all. [Full details in the privacy policy](/privacy/#leaderboard).

## How to join

Coming soon: the Leaderboard tab ships in the next extension release. Then: Install Claude Code and Codex Assist in VS Code, open its Leaderboard tab, sign in with your email and pick a username and visibility. Your history is uploaded once, then kept current in the background. Turning sharing off takes you off the board straight away.
