An open-source real-time dashboard for Formula 1 live timing and telemetry data.
F1 Telemetry connects directly to the F1 Live Timing SignalR feed — the same stream that powers the official timing screens during race weekends — decodes the payload in real time, and serves it over WebSocket to a browser-based analytics dashboard.
The goal is to give anyone a clean, fast, and accurate view into what is happening on track during any F1 session.
- Timing Tower — full leaderboard with positions, gaps, intervals, sector times, micro-sector segments, pit stops, tyre compounds and driver status. Multi-key sorting with tie-breaking and sequential position remapping to eliminate duplicate positions from the F1 feed
- Track Map — real-time driver positions on an interactive SVG circuit map with curvature-weighted segment boundaries, forward projection between micro-sector anchors, and smooth 60fps interpolation via
requestAnimationFramewith direct DOM manipulation - Race Strategy — tyre stint timeline showing compound, lap count, and mandatory stop indicator (FIA B6.3.6 compliance). Session-aware with cumulative stint positioning
- Pace Radar — speed trap and sector time rankings with all active drivers, position badges, tyre compound icons, and single-purple enforcement for the overall best
- Race Control — live feed of official messages, flags, safety car deployments, and steward decisions
- Weather — air and track temperature, wind, humidity, and rainfall in real time
- Qualifying Support — Q1/Q2/Q3 knockout detection with elimination line and separator labels between eliminated groups
- Data Resilience — handles F1's lossy feed gracefully: stuck
InPitflags are cross-referenced with stint data,Retired/Stoppedstates are permanently latched, and segment status2064(not-yet-reached) is correctly excluded from position calculations
This is a pnpm monorepo with three packages:
| Package | Path | Description |
|---|---|---|
backend |
apps/backend |
Node.js service that connects to F1 SignalR, decodes payloads, and broadcasts via WebSocket |
frontend |
apps/frontend |
Next.js analytics dashboard |

Shared TypeScript types and constants |
F1 SignalR (livetiming.formula1.com)
└── backend (Node.js + ws)
├── /health HTTP endpoint for frontend status polling
└── ws:// WebSocket broadcast to frontend clients
The backend subscribes to all available F1 channels. Compressed channels (CarData.z, Position.z) are decoded with raw DEFLATE. All channels are batched in 50ms windows before broadcast to reduce WebSocket frame volume.
# Install dependencies
pnpm install
# Start backend and frontend in parallel
pnpm devBackend runs on ws://localhost:8080 (WebSocket) and http://localhost:8081/health (HTTP health check).
Frontend runs on http://localhost:3000.
Environment variables are documented in .env.example at the project root.
pnpm dev:replayThis replays a pre-recorded session through the WebSocket server so you can develop and test the dashboard outside of race weekends. The replay server loops the recording indefinitely.
Note: Replay recordings may have incomplete data depending on when the recording started. Some micro-sectors, position updates, or pit events might be missing. During a live session, the data feed is significantly more complete and the dashboard behaves more accurately.
See docs/replay-mode.md for details on recording your own sessions and configuration options.

See CONTRIBUTING.md for setup instructions, code standards, and PR guidelines.
The live timing schema is reverse-engineered and may change between seasons. See docs/live-timing-types.md for guidance on keeping the types up to date.
