About ReplayPop
ReplayPop replays records as races. You pick a record, press play, and watch who led and when it changed hands.
Where the numbers come from
The numbers come from Wikipedia. Each page shows the date they were last read. Career totals are reported figures where Wikipedia lists one. The few added up from season rows are marked ~. The movement between seasons is estimated, and each page says where that applies.
How it is built
The site is built with Astro and runs on Cloudflare Workers. The races are drawn in plain TypeScript, with no chart library. The parsers that read Wikipedia are my own. AI coding agents wrote most of the code, working to my direction.
Using the races
You can use the races. Recording mode, on the NBA races for now, is there so you can put one on screen and talk over it. If you do, please credit ReplayPop. Copy credits gives you the line, with the photo credits included.
If you see a number that is wrong, tell me.
