It's truly amazing that a product with the reach of Lichess can be run so cheaply. Comments here criticizing the hosting costs extremely myopic - dev time isn't free, and doing a rewrite to chase down hosting savings isn't necessarily a good call.

I just signed up for a monthly donation. I complain about the ad supported internet all the time, but had never donated to LiChess. This thread is a good reminder of how far dollars to support projects like this can go.
