For people who'd like the joy of seeing their hobby engine face real people, Lichess has a nice system for verified bot accounts: https://lichess.org/team/lichess-bots
I'm personally running bits for sunfish https://github.com/thomasahle/sunfish and fastchess https://github.com/thomasahle/fastchess
There are way too many stockfish clones on there. I hope more hobby chess engine builders will join in.
