About tokenusage.dev
An independent, unofficial site about Codex and Claude Code token usage. Not affiliated with or endorsed by OpenAI or Anthropic.
Who runs it
tokenusage.dev, including the Reset Alerts service, is operated by Pistachio Technology Inc.
tokenusage.dev is run by the maintainer of token-counter, whose Codex and Claude Code plugins are public code. The site has no data of its own: every number here was sent by a sharer, normally through a plugin's share skill, and is self-reported.

How it relates to token-counter
token-counter counts the tokens in your own Codex or Claude Code logs and draws a report on your machine, with no network call. Sharing is a separate skill, and opt-in: only when you ask does it send a summary here, where it becomes a public profile, a row on the leaderboards and, if you include it, your report page at a link you can send. Each plugin counts a share from the same ledger as its local report, so the two agree day for day. The code that reads the logs and sends a share is in the plugins' repository.
Not official
This site is not affiliated with, endorsed by or sponsored by OpenAI or Anthropic. Codex and ChatGPT are OpenAI's products; Claude and Claude Code are Anthropic's. Plan names and prices are their vendors'. The token figures are sharers' own, and nothing here is a statement from OpenAI or Anthropic about what any plan holds.
tokenusage.dev is not related to tokenusage.org.
Handles
A handle is whatever its sharer chose. No one checks who is behind it, so a handle says nothing about who someone is or where they work. If one impersonates someone, ask for it to be taken down.
