Free scripts, DIY, or a platform: choosing a Roblox anti-cheat

By the waves.ac team · 6 min read · All posts

Search for a Roblox anti-cheat and you will find free scripts, open-source modules, and paid platforms, all promising roughly the same thing. They are not the same thing. This is the rubric we would use to choose one if we were not building one, applied evenly, including to us.

The four questions that actually separate them

Where does detection run? Anything that runs on the player's device can be turned off by the player you most need to catch. What happens when it is wrong? Every detector is sometimes wrong; the difference is whether a mistake is a log line or a banned innocent. What happens after the ban? If a banned cheater is back on an alt in twenty minutes, detection was theater. Who is accountable? A tool with no evidence trail leaves your moderators defending decisions they cannot explain.

Free client-side anti-cheat scripts

The most common starting point: a LocalScript that watches speed and teleports. Honest assessment: better than nothing against casual cheaters, and worth exactly what it costs against anyone with an executor, because the executor can delete the script. False bans are common since client-side detectors cannot tell lag from cheating. No evasion story at all. Fine for a small passion project; a liability the day your game has an economy.

DIY server-side checks

Validating remotes, rate-limiting, and server-authoritative math (we published a checklist in our guide on stopping exploiters) is genuinely the right foundation, and every serious game should do it whether or not they buy anything. Its limits are structural: it is one game's view of one account, it takes engineering time you are not spending on your game, and it comes with no review tooling, no evidence trail, and no answer to ban evasion. DIY is the floor, not the ceiling.

Paid platforms

This is the category waves.ac is in, so grade us with the same rubric. Detection: fully server-side, scored against each player's own baseline. Mistakes: every game starts in shadow mode where verdicts are visible but nothing is enforced, a lone weak signal can never ban, and every step below a network ban is reversible by your staff. After the ban: enforcement flows through Roblox's official Ban API with alt propagation, and WaveTrust makes a cheater's record follow them across protected games. Accountability: machine-readable evidence attached to every action, full audit log on every tier.

When evaluating anyone in this category, two red flags do most of the filtering. A vendor advertising IP or hardware bans is describing something Roblox does not expose to game servers, which tells you how the rest of their claims are calibrated. And a vendor who will not show you why a player was flagged is asking you to outsource your community's trust to a black box.

When you should NOT buy waves.ac

Honesty cuts both ways. If your game is single-player, has no economy, no leaderboard and no competitive stakes, cheaters mostly hurt themselves: do the DIY checklist and spend your money on the game. If your whole game is a sandbox where flying and teleporting are features, behavioral detection has little to push against. And if you want a tool that instantly permabans on the first flag, we are structurally the wrong choice, on purpose.

The short version

Free client scripts guard against players who were not going to hurt you anyway. DIY server hardening is necessary and not sufficient. A paid platform is worth it when your game has something worth protecting, and the one you pick should be judged on where detection runs, what happens when it is wrong, what happens after the ban, and whether it shows its evidence. That rubric is free, whoever you end up choosing.
