HelloUserBot

HelloUserBot does one thing without extra modules: when someone joins your group, it sends a formatted welcome message automatically, and it can say goodbye correctly when someone leaves too. It supports text formatting so the greeting can include bold, links or simple structure rather than a flat message.

Because it does not bundle moderation, captcha or analytics, it is the right pick if you already have those covered elsewhere and just want a clean, dedicated greeting bot rather than one more module inside a bigger all-in-one tool.
