Free forecasts for about 95 sports leagues, from models that publish their own track record.
Make honest sports forecasts free and legible: a win probability for every game or race, season and title odds, and a public record of how the models have done on seasons they never saw.
A model's settings are fitted once on tuning seasons and saved in version control. Every ordinary rebuild re-scores the holdout seasons with those frozen settings, so the track record cannot quietly improve by refitting on the seasons it is graded on. Refitting is a deliberate, committed act.
Each league is a small plugin on a shared kit of ratings, match and race models, simulations and backtests. A new league appears on the site the first time it is built, with no change to the site code, which is how the count reached 95.
Each league builds to JSON files served from Cloudflare's edge, so pages are fast everywhere and a traffic spike costs nothing. A Worker renders a snapshot of every page for search engines and answers the API: chat, live scores, accounts and the community.
Bookmaker and prediction-market prices sit beside the forecast on every game. It keeps the model honest in public and gives readers a second opinion without leaving the page.
GitHub's own cron can fire long after its time, which is useless during a live round. A tiny scheduler Worker checks every five minutes and starts the runs itself, including live rebuilds while games are on and a daily freshness watchdog that reports any league whose page is older than it should be.
Weather lookups, odds feeds and league APIs all cap requests. The pipeline caches everything it has already asked for, carries on without a missing piece and fills it in on the next run, and spends counted requests only where they change a page.
Anyone can read the discussions and chats; accounts can post. Every post passes a word filter and a cheap AI check before it appears, with rate limits per visitor and per address, so the boards stay usable without someone watching them all day.
The chat rooms hold open connections, which a normal deploy would drop. They live in Durable Objects in a Worker of their own, deployed separately from the site, so a site release never disconnects a room.
PodiumOracle is live at podiumoracle.com with about 95 leagues, rebuilt twice a day on self-hosted runners, with odds collected every three hours and monitoring through Sentry, Slack and PostHog. It is the product behind our data-pipeline and forecasting work for clients.
