What do we offer for you?

Sierra has been designed and developed by server owners, for server owners. We understand the troubles an average server owner might face with an anticrash and do our best to maximize the reliability of our software.

Accuracy

We aim to have the most precise and accurate detections possible. Precise detection prevents false positives, ensuring a smooth gameplay experience.

Speed

With our Netty-optimized code, we hardly collaborate with Bukkit at any point. As a result, Sierra can be used on servers with over hundrets of players without having a measurable impact on server performance.

Stability

No matter what your player count is, we ensure that Sierra is stable for every customer. Even under heavy load and responds instantly to attacks. No unnecessary overhead or lag.

Dependency free

Everything Sierra needs is already built in. No extra plugins needed—just drag & drop into your plugins folder, and your server is secured.

Compatibility

Due to Sierra's precise operation and the code it's built on, we have almost no compatibility issues with other plugins. Exceptions can be found in our documentation

Customer support

We are happy to assist every customer with any issue they might face with Sierra.
