Features

From the green flag to every screen in the building.

Raceline is made for the people behind the desk on a busy race day: quick to start a race, hard to get wrong, and clear for drivers to follow.

01

Drop-ins without the admin

Start a timed run with F5. In Auto mode every kart that crosses the loop joins by itself, so nobody has to type in kart numbers.

02

Group events, heat by heat

Build events from templates: warm-up, qualifying, B-final, A-final. More drivers than karts? Each stage is split into heats, and the next drivers are told to get ready.

03

Fairer finals

Balanced allocation ranks every kart by its best lap and gives the fastest ones to the drivers starting at the back. Or draw karts at random, or keep the same kart.

04

A hall screen that runs itself

Live timing, results and today’s best laps rotate on the big screen, with a QR code that opens the race on visitors’ phones.

05

Records with the weather

Track, kid-kart and wet records, each saved with the temperature, humidity and wind from SMHI or your own weather station.

06

Know your fleet

Hours and laps for every kart, tyre-change reminders, and a warning when a kart is slower than the rest of the fleet.

07

Results the moment the flag drops

When a race ends, results go straight to the hall screen and every driver’s phone, with each lap, best lap and speed. Printouts are there if you want them.

08

Diagnostics built in

A live decoder log, transponder signal strength, unknown transponders you can assign in two clicks, and a simulator for training staff.

Customisable

Set it up the way your track runs.

Every track runs its races and events its own way. Raceline adapts to your formats, your karts and your brand, and you can change it all yourself in the settings, without calling support.

Your race formats

Build your own templates, stage by stage: end by time or by laps, score by best lap or by race position, and pick who goes through to each final.

Your rules for karts

Keep the same kart, draw karts at random, balance them by speed or assign them by hand. Set aside spare karts and kid karts.

One race, three screens

The same race, wherever people are watching.

Race control

The staff desk: today’s schedule, the live timing table, flags and results, all with keyboard shortcuts.

Hall screen

Large timing that can be read from across the hall, with a high-contrast light mode for sunny outdoor tracks.

Phones

Visitors scan the QR code and follow their own laps: current lap, best lap, speed and every lap time.

For drivers and spectators

Follow the race from anywhere. No app needed.

Friends in the stands, parents at the café and drivers waiting for their heat can all follow along on their own phone. They scan the code and the race is right there in the browser.

The QR code is on the hall screen. Scan it with the phone camera and live timing opens straight away.
  • Scan and go

    Nothing to download, no account, no sign-up. It works on any phone with a camera and a browser.

  • Live timing online

    Positions, the current lap counting up, best laps and gaps, updated as karts cross the line. Tap a driver to see every lap.

  • Always know what’s next

    The hall screen shows what’s up next and which drivers should get ready for the next heat, so nobody misses their start.
