Why organizers choose it

No internet, no per-device installs, no license servers

One download and the whole tournament — server, console and judges' app — is live on your LAN.

🚀

Zero-friction setup

Download one package (Windows, macOS or Linux), launch it, and everything is live on your LAN. The launcher auto-updates itself on startup.

📡

Truly offline

Built for venues without reliable internet. The embedded database keeps all data on disk, survives restarts mid-tournament, and backs up by copying a single file.

📱

Judges bring their own devices

The ring operator displays a QR code; each judge scans it and starts scoring from their phone's browser in seconds — no installation needed.

⚡

Real-time by design

Scores travel over WebSockets and are routed in memory — benchmarked at roughly 1,000× the load of a real tournament (20 rings × 5 judges).

🌐

Bilingual out of the box

Every screen is available in English and Spanish, switchable at any time.

🔐

Secure where it matters

Administration restricted to the server host, ring access controlled by an IP whitelist per ring, and token-authenticated sessions.

ITF Brackets · the tournament console

The organizer's control center

  • Execution: rings, categories and the QR codes judges use to connect.
  • Red vs. Blue scoreboard with consolidated votes, timer, warnings and fouls.
  • Random Tul selector from the official list of 23 ITF patterns.
  • Awards: podium per category, marked delivered or pending at a glance.
  • ADMIN: scheduling with load balancing, IP security, category and judges management, data sync.

ITF Clicker · the judges' scoring app

Scan a QR, start scoring

A purpose-built scoring interface that adapts to each competition type, on any phone's browser — no app store, no install.

  • Individual sparring: red/blue panels with +1, +2 and +3, plus per-judge undo.
  • Patterns and prearranged sparring: both start at 10 points, judges apply deductions.
  • Breaking, child festival and team events: simple +1 tap counter per competitor.
  • A page reload or dropped connection never loses a score — the app recovers with one tap.
  • When the operator loads the next match, all judges' clickers clear and update simultaneously.

Tournament Server

The engine underneath

One process, one port: a Spring Boot (Java 21) server exposing REST APIs and WebSockets, and serving both web apps.

DB
Two modes

Embedded H2 or PostgreSQL

Zero-install file database for offline venues — live backup is copying one file — or PostgreSQL for production and multi-venue.

⚙
No rebuilds

Dynamic configuration

Frontend configuration served via API, plus interactive API documentation (Swagger UI) built in.

✓
Battle-tested

Proven concurrency

Automated tests covering 100 simultaneous scoring sessions, plus benchmarks of the hot scoring path.
