Spam reaches a group at different moments: at the join, in the first messages, or from people who never followed your channel. Each of these four bots acts at one of those moments. All four have a working free plan. They are made by the same maker, so this page compares them with each other only.

🛡️ Group Gate
…if spam accounts join and post right away. It stops accounts that never tap.
Open @GroupGateProBot →🧱 Group Shield
…if real members post promo links, or someone floods the chat.
Open @WordRaceGroupBot →📣 Subgate
…if the group belongs to a channel and you want writers to follow it.
Open @MostLikelyToProBot →🚪 Join Approve
…if you use join requests and admins cannot approve them fast enough.
Open @JoinApproveProBot →Group Shield and Subgate never check group admins, other bots or messages sent as a channel. So if you test a filter with your admin account, nothing happens, and it looks broken when it is not. Test with a regular member account, or ask a friend to post a link.
No anti-spam bot stops all spam, and these four say what they skip. Group Shield does not check edited messages, and a bare @mention is not a link to it. Group Gate is a one-tap check, not a puzzle: it stops accounts that never tap, not what people write later.
Group Gate's Pro link filter only deletes messages; it bans and mutes nobody.
* Join Approve: chats with 500 or more members are offered 300 Stars per 30 days instead of the one-time price. There is a free 24-hour Pro trial per chat.
