Keep Cursor plan limits in sight
Cursor usage is easy to lose track of because it lives inside the editor: plan allowance, Auto + Composer, and API spend do not show up in a Claude or Codex status line. A Cursor usage tracker is useful when you want those supported numbers visible before you start another long agent run.
UsageAtlas reuses your signed-in Cursor desktop session from read-only local state. It can show plan usage, Auto + Composer, API usage, and recent history, then place a remaining-capacity alert on the windows you care about.
See Cursor next to the rest of your stack
If Cursor is only one of the tools you pay for, a Cursor-only meter still hides the combined day. UsageAtlas adds supported Cursor activity to the same running total as Codex, Claude, and OpenCode. Filter to Cursor when you need an editor-only answer; open it back up when you want the whole picture.
History, weekday balance, and model mix help explain whether Cursor is carrying the project or merely filling gaps between other tools.
No extra Cursor login
UsageAtlas does not ask for a second Cursor password. It reads supported state already present from the signed-in desktop app, then renders bounded aggregates. Prompts and responses are not read, and credentials stay out of the interface.
Provider-reported limits can be delayed or incomplete. Treat UsageAtlas as a planning view, and confirm billing in your Cursor account when a number has to be exact.
Questions, answered
Can UsageAtlas track Cursor usage limits?
Yes. For supported Cursor windows, UsageAtlas shows plan, Auto + Composer, and API usage from your signed-in desktop session, including remaining capacity where the provider reports it.
Do I need to paste a Cursor API key?
No. UsageAtlas reuses the signed-in Cursor desktop session already on this computer. A separate UsageAtlas account is not required.
Can I see Cursor usage beside Claude Code and Codex?
Yes. Cursor is one supported source in the same local dashboard as Codex, Claude, and OpenCode. You can filter to Cursor or view the combined total.
