You can download the latest development version of ServerWrecker through nightly.link.

• GUI & CLI

• Supports SOCKS4 and 5 proxies

ServerWrecker currently supports these versions:

• Release (1.0.0 - 1.19.4 (latest))
• Beta (b1.0 - b1.8.1)
• Alpha (a1.0.15 - a1.2.6)
• Classic (c0.0.15 - c0.30 including CPE)
• Minecraft Bedrock Edition (1.19.70)

This includes every single subversion, not just a few specific versions. The latest Release and latest Bedrock Edition info may be out of sync with the latest development version.

Thanks to a built-in implementation of ViaVersion, ViaLegacy and ViaBedrock, a ServerWrecker bot can connect to all these versions even without the server having ViaVersion installed. The packet translation happens "client/bot side". This feature takes inspiration from services like ViAaaS and ViaProxy, which include client-side translation externally. ServerWrecker includes a similar implementation as these two proxies and is comparable functionality wise to ViaFabric.

Currently versions below r1.7.0 only support offline-mode, but a future version will support online-mode servers as well. All versions newer than r1.7.0 support online-mode.

This project is based on LambdaAttack, but over the years the code has been remade multiple times to be far more complex than the original project.
