TgGrow

TgGrow supports more distinct contest mechanics than most competitors — seven types in total, covering comment-based draws, reaction-based entries and referral (invite-a-friend) contests rather than just a plain subscribe-and-win format. It also exports the participant list to Excel, useful for admins who need to document a giveaway for sponsors or advertisers.

This makes it a better fit for admins who want variety across campaigns or need referral mechanics to grow a channel, at the cost of a slightly steeper learning curve than a single-format bot like Randomize.
