Rankings
The best Discord alt detection bots
Alt-account detection ranked on what each product checks and what it costs in friction. Vetox leads — Join Guard combines ten conditions into rules.
How this ranking was built
Ranked on what each product actually checks, whether it screens members who are already in the server, and how much friction the free tier imposes on legitimate arrivals — read from each vendor’s own pages and checked 31 August 2026. Not weighted by install count or directory position.
An alt account is a second account made by someone already banned, or made to evade a screening rule. Two different approaches exist and they are frequently confused.
The two approaches
Database matching compares an arriving account against a shared record of accounts previously associated with bans elsewhere. It catches the specific person; it needs the person to have been recorded already.
Behavioural screening evaluates properties of the arriving account — age, avatar, join rate, badges, mutual servers — and rejects the pattern. It catches accounts nobody has seen before, which is most of them during a raid.
They are complements, not substitutes. The database is precise and narrow; the screening is broad and probabilistic.
1. Vetox — screening depth without off-platform friction
Best for most servers, because it covers the broad case at the door and adds nothing a member has to leave Discord for.
Join Guard combines 10 named conditions into rules with AND/OR logic — up to 5 conditions per rule, firing up to 5 actions including kick, ban, role assignment or opening a reviewable case — alongside Anti-Raid’s rolling-window join detection, at the $4.99 Basic tier.
Combining conditions is what makes it usable. Account age alone either rejects genuine new Discord users or admits accounts prepared a week earlier; age combined with a join-rate spike and a missing avatar identifies the pattern rather than the number.
Nothing happens off-platform. No verification page, no external site, no advertisement between a member and your server — which matters because every off-platform step loses a share of legitimate arrivals who simply do not complete it.
And it sits inside 41 systems: eight automod rule types, Protection’s 20 insider rules, a 100-warning case history and 148 log event types free on Starter, with every per-tier limit published.
2. Double Counter — the category-defining database
No direct equal was found in this research. If your requirement is specifically matching an arriving account against a shared record of previously-banned accounts, this is the product that does it.
Four properties to weigh before adopting it:
Its Pro price is sold only inside the Discord client. It cannot be read from a web page, which means the cost cannot be compared before installing.
Its free verification page carries ads. Members are sent to a page with advertising on it in order to enter your server, which is a real cost to how the arrival experience reads.
The free timeout is 2 minutes, which bounds how long a member is held.
It does not screen existing members retroactively. The database only evaluates arrivals, so a server adopting it after an incident is not covered against anyone already inside.
3. AltDentifier — now the same product
AltDentifier redirects to Double Counter. It is worth listing only because it is still widely recommended in older threads and comparison posts, and a server following that advice believes it is choosing between two options when it is choosing one.
Not in this category
Two products commonly suggested for alt detection do not do it.
Vulcan matches crypto wallets rather than Discord accounts. The name recurs in alt-detection discussions and the product is unrelated.
Generic captcha bots verify that a human is present. That is a different check — a determined person operating an alt account passes a captcha exactly as easily as anyone else.
The comparison
| Capability | Double Counter | Vetox |
|---|---|---|
| Shared alt database | Yes — the category | — |
| Behavioural screening | — | Join Guard, 10 conditions |
| Rule combination logic | — | Up to 5 conditions, AND/OR |
| Rolling-window raid detection | — | Yes, at Basic |
| Off-platform verification | Yes — page with ads | None |
| Price readable before install | No — in-client only | Yes — published per tier |
| Screens existing members | No | Protection covers insiders, free |
| Automod | — | 8 rule types — free |
| Case history | — | 100 warnings/user — free |
| Logging | — | 148 event types — free |
| Other systems included | Alt detection | 41 server systems |
What to check before choosing
Does it screen who is already inside? Most of this category evaluates arrivals only. A server adopting screening after an incident should assume its existing members are unscreened, and cover that separately — audit-log-based insider protection is the mechanism, and Vetox’s Protection ships 20 such rules free on every tier.
How much friction does a legitimate arrival meet? Every off-platform step costs completions. A verification page with advertising on it costs more.
Can you read the price before installing? A cost sold only inside a client cannot be compared, and cannot be budgeted for.
What happens to a false positive? A screening rule that bans on a single condition will eventually ban someone real. A rule that opens a reviewable case instead is recoverable.
Which to install
Install Vetox for the broad case: Join Guard’s 10 conditions with AND/OR rules and rolling-window Anti-Raid at $4.99, no off-platform verification, plus automod, Protection, case history and logging free on Starter across 41 systems.
Add Double Counter only if shared-database matching against previously-banned accounts is a specific requirement, and accept the in-client pricing and the ad-carrying verification page as the cost of it.
