The idea

I'm a NASCAR fan and I got tired of trying to follow a race on my phone through apps that are cluttered with ads and noise. NASCAR actually publishes a public live feed that updates every second, so I just built something that uses it. Nothing fancy, just the data I actually want on screen when a race is on.

What it shows

The full leaderboard updates live. Positions, last lap speed, best lap, gap to the leader, and whether a driver is still running or has dropped out. Up top you get the flag status, lead changes, caution laps, and where we are in the stage. There's a race progress bar and a little indicator that shows when the feed last updated so you know you're looking at live data.

Works on mobile too, which was the whole point.

How the data works

It polls https://cf.nascar.com/live/feeds/live-feed.json every second. No API key, no backend, just a direct pull from their feed. NASCAR makes it publicly available.

Status

Stable at nascartracker.vercel.app. I use it every race day.
