Frequently asked questions

KombatControl is Italian software built to run BJJ, Ne-Waza, JJIF Fighting and Duo System competitions from registration to final standings. It handles registrations, weigh-ins, brackets, the multi-mat schedule, the referee table, the projected scoreboard and live public results, with the IBJJF, JJIF and FIJLKAM rulebooks already loaded.

All features →

Yes. KombatControl covers the same event cycle as Smoothcomp and Sportdata, but it is built around competition day: it counts every athlete's rest between two matches, works out whether each mat is ahead or behind after every finished match, logs result corrections and keeps the projector in step with the table. National federation rules, starting with FIJLKAM, sit on top of the international rulebook instead of replacing it.

Competition day →

KombatControl is the platform for running martial arts competitions: online registration, weigh-ins, automatic brackets, a schedule across several mats, a referee table with a projected scoreboard, and live public pages. It comes from the first-hand experience of people who organise competitions.

Only the referee table desktop app, for Windows, which also opens the scoreboard on the projector. Organisers, athletes and spectators use the browser, on a computer, tablet or phone.

What you need at the venue →

In five steps: create the event by choosing the rulebook, open registrations with a link, record the weigh-ins, generate the brackets and spread the categories across the mats, then run the competition live up to the podium. Categories, match times, scoring and bronzes come from the chosen rulebook, not from manual settings.

The five steps →

A Windows computer with the referee table app for each mat, and an internet connection. If you want the scoreboard in the hall, connect a projector or a second screen to that computer: the app opens its second window there.

The scales, the desk and the audience install nothing: weigh-ins are recorded from the browser or from the app, and everything else opens from a link.

What you need at the venue →

Online, from the event page, with an athlete account and naming their club: each athlete chooses their categories, and the organiser sees the entry list always up to date, without merging spreadsheets or emails.

The weight is recorded once and stays linked to the athlete. The rulebook decides when the weigh-in happens: IBJJF weighs during the event, JJIF before it. Category changes follow the federation's ladders for weight, age and belt.

From the valid entries, in the format the rulebook sets for their number: best of three, round robin or single elimination with any repechage. The bracket moves on by itself with every result confirmed at the table, and the final standings take the federation's shared placings into account.

Yes. Each mat has its own referee table, queue and scoreboard, and the organiser follows them all from one screen, with each mat's lead or delay recalculated after every finished match.

Mats ahead and behind schedule →

The KombatControl referee table has the commands of the match's rulebook: points, advantages and penalties for BJJ, and the JJIF scores and sanctions for ju-jitsu, with the clock. A second window puts the scoreboard on the projector, readable across the hall, and keeps it in step with the table in real time.

The match in progress doesn't stop: clock, score and projected scoreboard run on the table's computer, and the projector follows the table without going through the network. Recorded actions wait in a queue on the computer and go out by themselves, in order, as soon as the connection is back; the table always shows whether it is connected and how many actions are waiting.

Confirming the final result needs the server, because that is where the bracket moves on: without a connection the table says so and keeps the result in its window, ready to send.

If the network drops →

KombatControl counts every athlete's rest: the mat queue shows who is resting and until when, the table warns before the clock starts, and the projector shows the countdown. It warns without blocking: if the athlete says they're ready, the referee decides.

Rest, on the projector and at the table →

The table records the win by absence, and the bracket moves on as with any other result. Where the rulebook has a call procedure, as in JJIF Fighting, the table runs it with the clock on screen before confirming. An absence already known at the scales can also be declared from the entry, without waiting for the call.

From the referee table, on the finished match: while a correction is still possible, winner, points and type of win change and the bracket recalculates; once the category has moved on, the dispute is noted next to the match. Every change stays on record.

The correction, screen by screen →

Yes, with no app and no account: mats, the match in progress, brackets and results open from a link and update by themselves. Viewers are always read-only.

The public page →

Six official 2026 rulebooks: IBJJF BJJ GI, IBJJF BJJ NO-GI, JJIF Fighting, JJIF Ne-Waza, JJIF Duo System and, as the first national federation, FIJLKAM for Fighting, Ne-Waza and Duo System. Other national federations are added the same way, on top of the international rulebook.

The rulebooks compared →

It depends on belt and age. For adults: 5 minutes for white, 6 for blue, 7 for purple, 8 for brown, 10 for black. Juvenile 5 minutes for every belt, Masters 5 to 6, children 2 to 5. KombatControl applies them by itself, and you can change them from the event wizard by age division and belt.

With the IBJJF chain: more points, then more advantages, then fewer penalties. If it is still level, a referee decision is mandatory. The KombatControl referee table applies the chain of the category's rulebook.

IBJJF: weigh-in during the event, two automatic bronzes for the semi-final losers, no repechage; in a tie, points, advantages and penalties count, then the referee decision.

JJIF: weigh-in before the event, two bronzes fought against those coming back through repechage, and whoever loses the bronze match is fifth; in a tie, extra rounds in Fighting and golden score in Ne-Waza. KombatControl applies the rules of the chosen rulebook.

It is an ippon in each of the match's three parts: atemi, standing and ground. The match ends there. The KombatControl referee table recognises it from the score, declares it and asks for confirmation before closing, because once closed the bracket moves on. The same goes for disqualification at the second chui.

As matches: red couple against blue couple, from the same club, in the mat schedule like any other match. The jury has 3 or 5 judges, and with 5 the extreme scores are dropped; the table collects the scores series by series and the higher total wins. In a tie there is an extra series, then the referee decides.

Yes. The FIJLKAM rulebook adds the U8 division to JJIF, with its own limits: in Fighting 2 minutes, only the standing and ground parts, no full ippon, and the referee decides a tie; in Ne-Waza a minute and a half. In U8, U10 and U12, pools have at most four athletes.

Yes, from the event wizard: match times by age and belt, tie-break mode, automatic or fought third places, rest times, categories added, duplicated onto other belts or turned off. Everything else stays official, and you can always see whether a rule comes from the rulebook or from the event.

It is how the first competitions start on KombatControl: we set up your event's rulebook, categories and mats with you, and the price you start with stays locked even when the price list goes public. Places are limited, because we follow every event closely.

Apply with your event →

We reply within 2 working days. If the event is a good fit, we show you KombatControl on a demo built with your numbers: your federation, your categories, your mats. If you decide to go ahead, we load the rulebook, categories and mats together with you. Applying and the demo commit you to nothing.

The price list isn't public yet: we're defining it with the organisers in the founders programme, who keep their starting price. The demo on your event is free and with no commitment.

The founders programme →

In the European Union: the servers are in the Hetzner datacentre in Falkenstein, Germany, and no transfer outside the European Economic Area is planned. It matters, because minors compete too.

Demos run on sample data or on an export of your event, which we delete on request at the end of the session. Processing is described in the privacy policy.
