Where the rules live matters more than what they do
Command-driven bots are quick: type the rule, it applies. The trouble starts with the second admin. Nobody can see the current configuration without asking the bot question by question, a rule set by somebody who left is invisible, and a mistake is discovered by a member hitting it.
A dashboard turns the rule set into something you can read. Open the channel, see every module that is on, change one, and the next admin sees the same screen you did.
The same jobs, done from the web
Anti-spam and anti-flood, CAPTCHA verification on join, word and link filters, warnings with escalation, ban management, raid protection, and welcome messages. User tags and VIP handling for the members you treat differently. Analytics on messages, engagement and member growth so the weekly question has an answer.
All of it toggles per channel from Modules, and none of it needs code.
One setting that decides whether any of it works
A bot sees group messages only if it is an admin or has privacy mode disabled in BotFather. Moderation reads messages, so with privacy mode on the bot is present and blind. Check this first when a filter does not fire; it explains most of the cases where a tool looks broken on day one.
What it costs
Free covers one channel. Starter is $15 a month for three channels with the full moderation suite, welcomes and triggers. Pro is $39 for ten channels, advanced analytics and AI features. Business is $99 for unlimited channels and your own branded bot. Nothing on any plan limits how many members or messages you have.
Moving across
Add the bot as an admin, turn on the modules you need, and leave the old one in place for a few days. Two moderation bots do not conflict; they both act, and you find out quickly which set of rules you actually wanted.
