// FAQ
Is open source better than a paid bot?
Different, not better: maximum control and zero subscription cost against significant setup and strategy effort. Public strategies mostly fail live - your edge has to be yours.
Which open-source bot has the best community?
Freqtrade (Python) and Hummingbot (market-making focus) have the largest communities and most frequent releases. Both publish years of development history.
