Initial problem
When coding agents run across several tools and machines, it is hard to tell which project is using the budget. Teams and freelancers need costs they can assign to work and clients. That accounting should not require uploading prompts, conversations, or source code.
Implementation
Passcard reads the logs that supported coding agents already write locally. The desktop app assigns usage to people, repositories, projects, and clients, then sends usage records to a web dashboard. Installed hooks can warn before or block supported local actions based on recorded usage. The app also checks for exposed credentials locally; complete keys and chat text stay on the device.

Impact
What mattered
Local usage collection across Claude Code, Codex, Cursor, and other coding agents
Usage attribution and cost estimates by person, repository, project, and client
Budget checks and local hooks for supported agent actions
Local credential-exposure detection with masked findings and rotation tracking
Shared team workspace, client reporting, and organization billing
Insights
The landing page introduces usage tracking across tools and devices

The technical frame sits at the end on purpose: it shows the engineering substance behind the solution.
