This post lists EVE Online bots that are easy to set up. The main criterium for inclusion in this list is ease of use. The efficiency of the bot while running is secondary.
The links lead not directly to the bots themselves but to guides that explain how to set up the bot. To see a bot’s source code, you can follow the link in the corresponding catalog entry.
