Show HN: F1 COSMOS – Live timing and data dashboard for F1 fans
f1cosmos.com
What it does:
- Live timing: Real-time data updates in milliseconds - sector times, telemetry, team radio, you name it. No more refreshing pages or waiting for delayed updates.
- Replay feature: Missed qualifying or fell asleep during practice? You can replay the live timing from any past session. Pretty handy when you're in a bad timezone.
- Proper data visualization: I went beyond just showing lap times. There's race analysis with telemetry data, championship standings, technical updates, and a bunch of other stats that make watching races way more interesting. Oh, and the race calendar automatically adjusts to your timezone because I was sick of doing timezone math in my head.
- Multi-device setup: Here's the thing - I watch races on my TV but wanted data on my phone as a second screen. So I spent ages making the mobile experience smooth for exactly this use case. Desktop has customizable widgets if you're into that.
Technical stuff:
Built with modern web stack, focused heavily on real-time performance. The trickiest part was getting the data pipeline right for millisecond updates without everything falling apart.
Why I built this: Honestly, existing F1 apps either suck or cost money or both. I wanted something that just works and gives me all the data I actually care about in one place.
Been using it myself all season and figured others might find it useful. Currently supports English, Spanish, Japanese, and Korean (partially) - still working on expanding language support. Would love to hear what you think if you check it out during the next race weekend.
