"Which moderation bot is best?" has no universal answer: it depends on your goals. So instead of an abstract ranking, we'll compare four popular solutions by parameters that actually matter, and honestly say who each fits.
Briefly about each
Combot — a well-known name with strong activity analytics. Good if charts and stats matter; some features are paid, and newcomers will need to learn it.
Rose — a flexible modular bot for those unafraid of commands. Powerful filters and logs, but no web panel or entry CAPTCHA, and the rule syntax scares off beginners.
ChatKeeper — a solid all-rounder with a web panel, anti-spam and welcomes. One of the most balanced options, though not everything is free.
Mod Assistant Bot — an all-in-one solution with semantic moderation, a web dashboard, verification, channel features and a 50+ language interface.
By parameter
Anti-spam
Combot and Rose filter by words and links; ChatKeeper adds behavioral rules. Mod Assistant Bot goes further: it analyzes the meaning of a message, so it catches reworded spam and scams that bypass word lists.
Entry verification
Combot, ChatKeeper and Mod Assistant Bot have a CAPTCHA. Rose has no entry CAPTCHA — a notable downside for open groups where bots join in batches.
Channels
Rose and Combot are mostly group-oriented. ChatKeeper and Mod Assistant Bot work with channels; Mod Assistant Bot has scheduled posting and auto-delete out of the box.
Ease of setup
Rose is configured by commands — powerful but complex. ChatKeeper, Combot and Mod Assistant Bot have a panel; Mod Assistant Bot puts all management in one web dashboard.
Languages
Combot, Rose and ChatKeeper are mostly RU/EN. Mod Assistant Bot offers 50+ languages, which is critical for international communities.
