Sorry for late reply. I can add Raydium and Jupiter, no problem with that. And yes, it's completely free. Users can send donations for me if they want.
Edit: Added new group link and updated text.

Your bot could actually get more popular if it ended up getting advertised on platforms like Dextools or dexscreener but given that it's not making money for you through subscription, I understand.
