About:
UndercutF1 is a terminal-based live timing application that streams real-time Formula 1 telemetry data directly to your console. It allows users to set a variable delay buffer, ensuring the live data stays perfectly synchronized with a television broadcast. The tool supports detailed session views including timing towers, sector times, and tire compounds for all F1 sessions.
Key Features:
  • Variable delay buffer to sync with TV broadcasts
  • Rich terminal user interface (TUI) with timing towers and telemetry
  • Support for all session types: Practice, Qualifying, Sprint, and Race
  • Detailed tire compound and DRS status tracking
Use Cases:
  • Syncing live F1 telemetry with a TV broadcast to avoid spoilers
  • Monitoring detailed sector times and tire strategies on a second screen
  • Viewing race control messages and penalties in real-time
Alternatives:
  • f1multiviewer – F1MV is a GUI-based desktop application requiring a browser, whereas UndercutF1 is a lightweight CLI tool.
  • f1-timing-stream – A Python script approach that requires manual setup; UndercutF1 offers a pre-packaged, interactive TUI experience.
