A full-featured Formula 1 terminal UI built with Go and Charm
Real race analysis, live standings, circuit track maps, pit stop insights, AI chat, and a growing deep-dive Race Analysis mode — all in your terminal.
A dedicated deep-dive view for any completed session — navigate to any race weekend and explore 9 interactive charts:
| # | Chart | What you see |
|---|---|---|
| ① | Strategy | Per-driver tyre stint timeline — compound colours, lap counts, undercut/overcut windows |
| ② | Sparklines | Per-driver lap-time sparklines across the full race — identify degradation and purple laps at a glance |
| ③ | Pace | Box-plot style pace distribution per driver — median, spread, outlier laps |
| ④ | Sectors | Sector-by-sector time breakdown per driver across all laps |
| ⑤ | Speed Trap | Top-speed trap readings per driver — straight-line performance comparison |
| ⑥ | Positions | Position changes chart — every driver's race trajectory lap-by-lap, right-anchored finish sidebar |
| ⑦ | Team Pace | Constructor-level pace comparison — team median vs field |
| ⑧ | Pit Stops | Ranked pit stop duration bar chart (see below) |
| # | Tab | What you get |
|---|---|---|
| 1 | Dashboard (WIP) | Live timing — being rebuilt on top of the official F1 live-timing protocol |
| 2 | Standings | Driver & Constructor championship standings with team-coloured proportional bar charts |
| 3 | Schedule | Full season calendar grouped by month. Cursor-navigate with j/k. Next race auto-highlighted |
| 4 | Weather | Air temp, track temp, humidity, pressure, wind speed/direction, rainfall + sparkline trend charts |
| 5 | Ask AI | Chat with Groq's compound-beta model (live web search) — race strategy, regulations, history |
| 6 | Track Map | Real circuit outlines rendered from GPS coordinate data. Corner numbers overlaid. s to simulate any GP, along with Heatmaps of driver speed |
| 7 | Driver Stats | Per-driver lap-time sparklines, best/avg/worst laps, sector trends, lap histogram, pit stop counts |
| 8 | Race Analysis | 9-chart deep-dive for any session — strategy, pace, positions, pit stops, sectors, speed |

A custom Go server that connects to the official F1 live-timing SignalR feed (livetiming.formula1.com) and broadcasts a clean WebSocket/JSON stream that the TUI subscribes to:
- Reverse-engineered SignalR handshake + subscription topics:
TimingData,CarData.z,Position.z,RaceControlMessages,TeamRadio,SessionInfo - Real-time sector splits and mini-sectors per car
- Per-car telemetry: speed, throttle %, brake %, gear, RPM, DRS state
- Race control messages (SC, VSC, red flag, penalties) piped live into the dashboard header
- Live gap tree: delta to leader, delta to car ahead, racing interval
- On-track battle detection — automatic highlight when two cars are within 1 s
Rebuild the dashboard as a unified live race command centre:
- Animated driver dots on the real circuit outline (GPS X/Y positions from
Position.z) - Side-by-side track map + live timing table + mini gap sparklines
- Real tyre age counters ticking per lap
- Weather overlay: real-time track/air temp, rain probability
- Team radio clips — playback URLs streamed from
TeamRadiotopic
- Tyre degradation model — fitted lap-time slope per stint, visualised as a trendline on sparklines
- Undercut/overcut detection — flag when a driver gained/lost position via pit stop timing
- Interactive session picker UI (rather than config flag)
- Head-to-head driver comparison mode across any two drivers
- Animated replay of race positions chart with a lap scrubber

v1 was vibecoded. v2 is structured, data-accurate, and built to be extended. v3 brings it live.
