• Claude Usage MonitorUsage limits of several Claude accounts on the phone2026

  A page built for the phone shows the limits of several Claude accounts in real time, with a countdown to the reset and the rate at which the quota is shrinking. Each account signs in through its own OAuth with PKCE, so the logins on the computers stay valid. The service needs nothing beyond the Python standard library and can also wake a server via Wake-on-LAN.

  Built with Python, OAuth 2.0 (PKCE) and Docker

• Claude FleetA macOS overlay for running coding agents2026
