🪶 CapPreventer is the only updated AAE (anti-anti-exploit) free plugin on the market.

CapPreventer tries to block popular anti-exploit mods, so your server can see players' mods without any spoofers.

CapPreventer strives to be the top AntiSpoof Pro alternative. If you want to help me achieve that goal, you may report any cool findings for the plugin's development in my Discord DMs.

🔍 Made for
| Mod(ule) | Operation | Versions |
|----------|-----------|----------|
| Server Spoof (optional impl.: Meteor Client, Opsec) | detects / breaks¹ | all |
| Opsec | breaks | <v1.1.5 (alone), i lost track, new unpatched (requires at least one of some common mods) |

¹ Whether it breaks or detects is dependent on the module configuration. In OpSec <=v1.1.6, it always breaks.

📮 Outdated handling²

• Opsec v1.1.5                                                             🔴 outdated [breaks]
• ExploitPreventer v1.0.5 x Server Translation API 🔴 outdated [breaks]
• ExploitPatcher                                                       ⚫ taken down [breaks]

² These operations only work on outdated versions of the given mods.

🪧 Newest Protection

To have your server use the newest CapPreventer protection methods, remember to keep it updated.

I am trying my best to always find new exploits when old ones get patched.
