The honest FiveM anti-cheat comparison (2026)

Server-side vs client-side vs kernel — what each one actually detects, the leak problem nobody mentions, and how to choose. Author's note: I help build BlackGuard, one of the anti-cheats discussed below. I've tried to keep this genuinely balanced — including BlackGuard's real trade-offs — because a buyer's guide is only useful if it's honest. Verify current pricing before you buy; this space changes fast.

Your server just got hit

Someone spawned a few million in cash, teleported across the map, and now your Discord is on fire. You go looking for an anti-cheat and every website says the same three things: "advanced detection," "trusted by thousands," "99.9% protection." None of that tells you what you actually need to know. So here's the real breakdown — what these tools detect, what they cost, and the one architectural question that decides everything.

First: where does the anti-cheat actually run?

This is the question nobody explains, and it determines what a tool can and can't catch. There are three broad approaches:

• Client-side — code runs on the player's machine. It can see injected mod menus, Lua executors, ESP overlays, even memory readers. Powerful — but the detection code lives on the cheater's computer, so it can be reverse-engineered and leaked.
• Server-side — detection runs entirely on your server. It watches what reaches the server — impossible movement, teleports, injected money, unrecognized resources — and there's nothing on the client to leak or bypass. The trade-off: a pure server-side tool generally can't see external/out-of-process cheats (e.g. DMA hardware readers) that never touch the server.
• Kernel-level — a driver runs deep in the player's OS. Maximum visibility, maximum intrusion — and the FiveM community pushes back hard on software that digs that deep (false positives, compatibility, trust).

Hold onto that framing. Every product below is really just a set of choices along this spectrum. We go deeper in server-side vs client-side.

The leak problem (the part the marketing skips)

FiveM anti-cheats get leaked and decrypted on cheat forums constantly. When a cheat developer can read your detection code, they build targeted bypasses — so a leaked anti-cheat's effectiveness decays over time. Several of the most popular client-side products have had their full source (sometimes including the admin panel) reported put up for sale on leak forums — occasionally for less than one month's subscription. That doesn't make them worthless, but it's a real factor the "trusted by thousands" badge won't tell you. This is the single strongest argument for server-side detection: there's no client code to leak in the first place.

The contenders (honest rundown)

Prices are mid-2026 and change often. "Claims" = the vendor's own marketing numbers; "reported" = stated by multiple third-party comparison guides. Verify current pricing and claims yourself before buying.

What actually matters when you choose

Skip the buzzwords. Ask these:

1. Has the source been leaked? A leaked client-side anti-cheat decays fast. Server-side designs sidestep this entirely.
2. What does it gate behind higher tiers? If aimbot detection isn't on the plan you can afford, you're paying for incomplete protection.
3. How does it handle false positives? Auto-banning everything feels powerful until it bans a legit whale — globally. Flag-first + easy revoke beats aggressive auto-banning for most communities.
4. Kernel or not? Kernel-level catches more but creates real player-trust friction. Decide if your community will accept it.
5. External/DMA cheats — do you actually face them? Most servers don't. If yours does (high-stakes competitive), you need a client/kernel tool; if not, server-side is cleaner.
6. Is it actively maintained? An out-of-date anti-cheat is a bypassed one, regardless of who made it.

Bottom line

There's no single "best" — there's best for your situation:

• Facing hardware/DMA cheats on a competitive server? A dual + DMA tool (like Raven) or a kernel tool earns its keep.
• Large RP community with dedicated staff? A monitoring-heavy or network tool may be worth the cost and intrusion.
• Want transparent, no-kernel, server-side protection with nothing to leak — and don't need DMA coverage? That's BlackGuard's lane, and the design is built around it.
• On a tight budget? A budget tool like AnvilAC, or a well-configured free option.

Whatever you pick: check that it's actively maintained, layer it with server-side validation and a whitelist, and don't trust any "99.9%" badge. The right anti-cheat is the one whose trade-offs match your server — not the one with the boldest landing page.
