Features

Built for the chaos of race day

Everything you need from the first sign-up to the final medal ceremony — and the reports to hand out after.

Distributed Registration

Invite group leaders to manage their own rosters. Import from spreadsheets or add participants one by one.

Works Offline

No gym WiFi? No problem. Everything runs in the browser and works without an internet connection on race day.

Smart Scheduling

Lane-balanced heats generated automatically using proven algorithms. Every racer gets a fair shot in every lane.

Live Audience Display

Project results for the crowd on a big screen. Dramatic medal reveals, live leaderboards, and staging previews.

Handle the Unexpected

Late arrivals, broken cars, DNFs — RallyLab adapts. Re-run individual lanes, end early, add extra rotations, or swap lanes mid-race.

Track Integration

Connect a Raspberry Pi Pico W for automatic timing. Live sensor diagnostics, auto pin mapping, and WiFi or USB — or enter results by hand.

Reports & Export

Generate PDF reports for the whole rally, individual sections, or scout groups. Export detailed Excel workbooks with standings, heat results, and statistics.

Car & Lane Analytics

Per-car statistics across every lane, lane deviation diagnostics to spot track issues, and live leaderboards updated after every heat.

How It Works

Three steps to race day

1

Set up your rally

Create sections, invite group leaders, and collect rosters. Everyone manages their own registrations online.

2

Run race day

Check in participants, generate heats, and record results. The operator console handles the entire flow.

3

Celebrate

Leaderboards update live as each heat finishes. Final results are revealed dramatically — medals and all.

Works for any Scouting program

Whether you call them Kub Kars, Pinewood Derby, or something else entirely — if your Scouting group races small wooden cars down a track, RallyLab has you covered. Sections and terminology are fully configurable.

STEM Learning

A real project youth can hack on

RallyLab's track controller is a Raspberry Pi Pico W running MicroPython — open source hardware and software that youth can explore, modify, and make their own.

Python

The firmware is MicroPython — the same language taught in classrooms, running on real hardware.

Electronics & Raspberry Pi

LEDs, sensors, breadboards, and a $6 microcontroller. Tangible circuits youth can build and debug.

Open Source

All code is on GitHub. Youth can read it, fork it, break it, fix it — the way real developers learn.

Free forever. Open source.

RallyLab is MIT licensed — no server to maintain, no subscription, no catch. Built by a Scouting volunteer, for Scouting volunteers everywhere.
