Best Discord Anti-Raid Bots 2026: Join Filters, Anti-Nuke and Server Protection

Two very different attacks get filed under one word. A raid is a flood of accounts joining at once to spam or harass. A nuke is a single account with permissions deleting your channels and roles. Blocking the first does nothing about the second, and most servers discover the distinction on the day it matters.

Raid, Nuke and Alt: Three Problems, Three Defences

DefinitionDiscord anti-raid bot

A bot that detects an abnormal rate of joins and applies an automatic response — kicking, banning or muting the joining accounts, and optionally locking the server down — based on thresholds such as joins per time window and minimum account age.

The defences do not substitute for one another. A raid is a volume problem, answered by a join-rate threshold and an account-age floor. A nuke is a permissions problem, answered by watching the audit log and punishing the executor faster than they can finish. Alts are an identity problem, answered by join filtering on the signals a throwaway account gives off. A server with only the first is protected against the least damaging of the three.

Anti-Raid and Protection Across the Major Bots

Anti-raid is one of the better-served categories — most all-in-one bots ship something. The differences are in what an attack has to look like before the bot reacts, whether the nuke case is covered at all, and what the free plan includes.

Protection: The Anti-Nuke Layer, on the Free Plan

Vetox Protection watches the Discord audit log and reacts to dangerous administrative actions rather than to messages. When a monitored action fires, the executor is punished according to your configuration — and the action itself can be undone, so a deleted role comes back rather than merely being avenged.

Anti-Raid: Join-Rate Detection and JoinGuard

Anti-Raid handles the volume case. You set how many joins within how many seconds counts as a raid, the minimum account age you will accept, and what happens when the threshold trips. JoinGuard then adds conditional filtering on individual joins, so an account that looks disposable is handled on arrival rather than waiting for a crowd.

The JoinGuard action list is the part that repays a few minutes of configuration. Not every suspicious join deserves a ban: assigning a restricted role, or opening a case for a human to look at, catches the accounts a hard filter would have wrongly removed. Defence that produces false positives quietly is worse than defence that flags them.
