Live Scout.
The Sauce for Zwift alternative: your race on a phone, tablet or second screen
BETAPhone on the bars, a tablet beside you or a second screen, your choice. Live Scout shows you what the field is doing right now and already knows every rider lined up with you. It runs in the browser next to any Zwift setup, Apple TV included. The game itself is left alone.
During the race, at a glance
Watts, zone, reserve
Your 3-second average, the zone relative to your CP and how much reserve you have left. Worked out from your own CP and W′, not a flat default.
Group and draft
How big your group is, what it is riding, the seconds to the front and the back, whether the gap is closing right now. Your draft in percent.
Next segment
Distance, length, gradient, calibrated from real races. And how long it takes at your pace.
Riders around you
Category, racing score, power curve, reserve. Anyone whose curve looks like yours is marked.
Signals
Attack from the team, split, segment in 500 m, reserve running low: as a banner, a tone, or spoken into your earphones if you want.
Team and captain
In a club room everyone follows the same race. The team bar shows each of your own riders, the captain watches from outside and gets lines that follow from the numbers.
What only Live Scout knows
The field is settled before the gun goes. For every rider there is a power curve from 5 seconds to 20 minutes, plus CP and W′, phenotype and racing score, taken from public race results and dated. That is where the reserve readouts for strangers, the twins in your field and the duel at the next segment come from, over exactly the duration that segment demands. It is the Race Scout analysis, carried on into the race.
Fair and frugal
You see what ZwiftPower, zwiftracing.app and Sauce show as well, in one place and readable while you ride. Other riders' weight and age group appear the way ZwiftPower shows them, but are never stored. You never see a heart rate as a number, only a heart when someone is riding at their limit; it is not stored either, and neither is any other live data. If an organiser says no HUD, the phone stays in the pocket.
How to get in
Sign in with your Zwift ID. Your club manager unlocks you, or you put yourself on the list. For the live view you add a second, free Zwift account once; it must not be your rider account, or the game kicks you out mid-race. The password is stored encrypted and only used during a race.
Who builds it
Live Scout is the work of two friends. The wizard behind the live core goes by pattn (Patrick Romer): he built the Zwift data client that listens in with no game running, and on top of it the group and attack detection, the segment learner and the race director. Five to six packets a second, the whole start group in view, proven in real races. Data, platform and the browser surface come from VFWorks, with more than 159,000 profiles and a power curve for each of them. Partners in crime, both with the same line in their heads: data beats opinion.
Compared with Sauce for Zwift
Sauce reads the game traffic on your computer and shows watts, groups, gaps and draft in a window over Zwift. It is fast, freely configurable and has been around for years. It needs the computer that runs Zwift, though: there is no Sauce on Apple TV or iPad, and on a single screen the window sits on top of the game.
Live Scout runs in the browser, on a phone, tablet or second computer, and the data stream comes from a server of its own. And the field is known before the start: Sauce sees what the game is sending right now; Live Scout also knows what every rider can do over 5 seconds to 20 minutes.
Sauce for Zwift is a product of Sauce, LLC, and Zwift is a trademark of Zwift, Inc. This project is independent of both. Curves from public race results (D-15), rule-based, no AI black box. Sport, not medicine.
