As the FIFA World Cup 2026 reaches its final stages, millions of fans around the globe are glued to every match. The Ruby community is no exception.
Over the past few weeks, we’ve seen several developers build and share open-source Ruby and Rails applications inspired by the world’s biggest football tournament. From prediction pools and tournament managers to live leaderboards and match simulators, these projects showcase both creativity and the versatility of the Ruby ecosystem.
Here are a few that caught our attention:
🏆 La Quiniela
Repository: https://github.com/emilio2601/la-quiniela (replace with the correct repository if different)
Live demo: https://quiniela.emilio2601.dev
A Rails 8 prediction pool with an original scoring system that rewards players for spotting unlikely results. Rather than awarding one point per correct prediction, each correct pick earns points based on how many other participants it beats. The application is fully server-rendered using Hotwire and modern Rails components including Solid Queue, Solid Cache, Solid Cable, Propshaft, and PostgreSQL.
🌎 World Cup 2026
Repository: https://github.com/DArceCampos/World-Cup-2026
A complete World Cup management platform featuring a Rails 7.1 REST API and a React + Vite frontend. It includes group management, standings, knockout stages, match administration, and automatic tournament simulations through a clean service-oriented architecture.
🎯 2026 FIFA World Cup Pool
Repository: https://github.com/danecjensen/world-cup-pool
A traditional prediction pool built with Rails 7.2, PostgreSQL, Hotwire, Tailwind CSS, and Devise. Players predict both the group stage and knockout bracket, while administrators manage official results through a dedicated admin interface.
⚡ PitchPredict
Repository: https://github.com/dr-bizz/pitchpredict
A modern Rails 8 score prediction game demonstrating many of the latest Rails features, including Turbo Streams, the complete Solid stack (Queue, Cache, and Cable), Propshaft, Importmap, Tailwind CSS v4, and Progressive Web App support with live-updating leaderboards.
It’s always exciting to see developers building projects around global events, and the World Cup has inspired some fun and technically interesting Ruby applications this year. Whether you’re looking for Rails architecture ideas, experimenting with prediction games, or simply enjoying the tournament, these repositories are well worth exploring.
And, as an Argentine, I have to admit I’ll be glued to the remaining matches, cheering on La Albiceleste. 🇦🇷
