Thousands?

It's a 60kb Javascript file, seems quite static to all users, and appears to be cached and delivered from CloudFlare. I don't think their free accounts have bandwidth limits, just feature limits, so... it's probably more "pennies" on hosting than "thousands." Given the popularity of it, it's a good bet that it's almost always in the CF cache, so very few requests going through to the origin.

This is more of a "You could host it on a home ISP" type project with how well caching systems handle it. Or toss it in a Google Cloud Storage bucket, which has reduced egress fees to CF and it'll still be constantly cached.

Nothing I see indicates it's the slightest bit expensive to host.

From what I can tell it's all client side, including all 5 letter words. You could host it pretty cheaply.

I think part of the success of wordle was the network effect of having a single word to share your success or failure with everyone who's playing. For a group of friends you could probably get people to switch but there's still the wider population effect of the shared puzzle each day. That second is much harder for any copycats to replicate.

He's probably paying tens of dollars per month if he put Cloudflare in front of it.
