I update the list at

- Which play against bots, computers and/or humans? (22a = bots, 22b = computers, 22c = humans)

@Ajile it would be nice to maintain a spreadsheet with columns of your list filled with BOT lines.

Here are the numbers for PyChessBot
1, 7, 8, 11abcdefghi, 12abcde, 13c, 16c, 20, 21, 22c

Thank you @gbtami

I've created a spreadsheet at

I spreadsheet !

1, maybe 2 too, 3, 4, 7 (when necessary), 8, 11a+11c, 12f, 13b (+13a, if the opponent is BOT too or don't care about possible problems with lichess cheat detection), 16c, 20

GarboBot runs on the GarboChess-JS engine.

1, 11a, 12abcdefg, 13c, 16c, 20

@Ajile there is a variant called "from position" BOT authors can support. This is not a real variant game type but enables to create arbitrary starting positions to play from. See for example :) All in all add 11j="from position" to the list please!

That's a great idea! I've added it to the list on There currently seems to be something wrong with the ethercalc list, so I haven't updated that one yet.

I've updated and

I've also created a survey for people who have created a lichess BOT at
