Questions.

It's built not to. Every flag is checked against 36 game mechanics and your server's TPS, and has to repeat before it counts. Movement checks only alert by default. If you're ever unsure, /sentinel observe on makes the whole plugin log-only.

No, on purpose. Cheat clients can report the same name as performance mods, so a name check can't tell them apart. SentinelAC looks at what a player does instead, so private clients are caught the same way.

Reach, killaura, multi-aura, auto-clickers, hits through walls, auto-totem, speed, fly, no-fall, water walking, timer, nuker, fast place, block reach and freecam. The checks page lists all 20.

When TPS drops below the floor you set, movement and timing checks stop and wait until the server recovers. Flags that happened during lag are marked in /sus and count for less.

Yes. Every check has a mode (observe, alert or kick) and its own limits in config.yml. Change a mode in game with /sentinel mode <check> <mode>.

Only if you want it to. After five real kicks inside the window, SentinelAC gives a timed ban. Alerts and observe findings never count toward it. You can turn auto-ban off or change the numbers.

Any anti-cheat can be tuned around given enough effort. SentinelAC's advantage is that it doesn't rely on a list of known clients, so there's nothing to rename or hide.

Anyone with the sentinel.sus permission. Kicking, banning and freezing each have their own permission, so you can give helpers read-only access.

No. Staff watching through /sus are hidden from the tab list and from the player being watched.

Their game mode and position are saved to disk before they enter spectator. On their next join they're put back exactly where they were.

Yes. Colours and icons are in gui.yml, every message is in lang/en_US.yml, and both reload with /sentinel reload.

A website where you can see your license key, every connected server and a live feed of alerts. It's included with every license.

No. The plugin works fully on its own. Alerts only reach the dashboard after you add your license key to config.yml.

For each alert: the player's name and UUID, the check, its level, the reading, world and ping. Plus your server's name, version and player count. Nothing else, and nothing about players who aren't flagged.

The latest 10,000 alerts per license. You can clear them any time from the Alerts page.

Rotate it from the License page. The old key stops working immediately; paste the new one into your config and reload.

Paper 1.21 and its forks, like Purpur and Pufferfish, plus Folia. It needs Java 21. Spigot and Bukkit aren't supported.

Yes. The same file detects Folia and runs each task on the region that owns it.

No. SentinelAC has no dependencies. PlaceholderAPI is optional.

It can run alongside them, but two anti-cheats kicking for the same thing makes false kicks more likely. If you keep another one, set overlapping SentinelAC checks to alert.

The checks run on events the server already fires, and saving happens on a background thread. On a normal server the cost is a small fraction of a millisecond per tick.

$9.99, paid once for a license.

Your license key shows on the confirmation screen and in your dashboard, where you can also download the plugin.

Yes, on the servers of one network, like a lobby and its game servers. A separate network needs its own license.

Every V1 update is included.

If SentinelAC doesn't work on your server, ask within 14 days. See the refund policy.
