ChatZilla pricing: it is free

Yes. There is no paid plan today: verification, filters, anti-spam, triggers, statistics and everything else on this site work in every group at no cost.

Post, edit and delete messages, plus restrict members (to ban spammers). The mini app's Add chat button pre-selects these rights. Without delete rights the bot can't remove anything.

No. Messages from group administrators skip the filters and verification, so you can post links and media freely. Triggers still answer admins, so you can test them yourself.

Verification works together with the filters: set at least one filter to "Only for validated users". New members then have to pass the check before they can write in the group. The Subscription type is an exception: it checks every message of a non-admin on its own.

Yes. Every topic is moderated, and the language filter and triggers can also be set for a single topic.

Yes, through join requests. Turn on "Approve new members" in the group's type settings, then enable join requests in the mini app. The bot greets the applicant, can test them and auto-decline spam profiles, and admins decide with one tap.

No. In a group the bot's notices are private: only the member they are addressed to sees them, and Telegram removes them by itself. Public bot messages, such as a ban notice or the /rating answer, delete themselves after a time you choose in Bot Message Settings, from 5 to 60 seconds, or you can keep them.

ChatZilla filters by content type. To find and delete NSFW images, videos and stickers, add our @NudesRemoverBot next to it.

Yes. In the mini app, Team Management gives other people access to the group's settings without making them Telegram admins.
