Subgate in short

Subgate checks channel subscriptions when members write in a Telegram group. An unsubscribed member is restricted and gets a channel link with an I subscribed button for a fresh check.

Limits

  • One required channel is free. Setting another channel on the free plan replaces the previous one.
  • The bot must be a channel admin, including for private channels. Private channels need an invite link the bot can use or permission to create one.
  • Group admins are never checked. Bots and messages sent as a channel are skipped. A successful check is cached for 10 minutes; a failed lookup does not restrict a member.

Facts checked against the bot on .

Subgate runs as @MostLikelyToProBot. When a member writes without subscribing to the required channel, the bot deletes that message if it has permission, restricts the member and shows a channel link. After subscribing, the member taps I subscribed for a fresh check and can write again under the group's usual permissions.

Make the bot an admin of your group with permission to restrict members and delete messages. Make it an admin of the channel too, then send /setchannel @channel in the group. Use your channel's actual username in place of @channel.

Group admins are never checked. Bots and messages sent as a channel are skipped too. If Telegram can't confirm membership, the bot doesn't restrict the member. A successful subscription check is cached for 10 minutes, so leaving a channel isn't detected immediately.

Commands

CommandExampleDoes

/removechannel/removechannel @channelStop checking this channel. With only one channel, the argument can be omitted.
/settext/settext {name}, please subscribe before writing.With Pro, set the text above the buttons. {name} inserts the member's name. Use /settext reset to restore the default.

FAQ

Does it work with private channels?
Yes. Make the bot a channel admin and send /setchannel with the numeric channel ID, or omit the argument for the group's linked channel. The bot needs a usable invite link; if none is available, it needs permission to create one.
Are admins required to subscribe?
No. Group admins and owners are never checked. Test with a regular member account. The check starts when a member writes, not when they join.
What does Pro cost?
Pro is optional and costs 150 Stars once per group. It allows up to 3 channels and your own text, and removes the footer. One channel stays free. On the free plan, setting another channel replaces the previous one.
What if the bot loses access to the channel?
When it can't verify membership, it doesn't restrict anyone on that failed check. Restore its channel admin access and group permissions. A member already restricted by the bot can subscribe and tap I subscribed for a fresh check.
