StressCraft (work in progress)

State-of-the-art Minecraft stress testing software written in Kotlin.

Disclaimer

StressCraft should ONLY be used in your own server environment. We do not endorse the use of StressCraft for any other purposes than testing your own infrastructure.

Please be aware that attempting to execute this with an external server as a target can be seen as illegal as it simulates a layer 7 DoS (denial-of-service) attack, which is against the law in most countries.

How to use?

NOTE: DO NOT DO THIS IN PRODUCTION, EVER.

• Ensure max-players (server.properties) is high enough for the number of bots you're planning to test
• Set online-mode (server.properties) to false
• Set network-compression-threshold (server.properties) to -1
• Set connection-throttle (bukkit.yml) to -1
• Increase max-joins-per-tick (paper.yml) to your liking
• Execute the jar with proper arguments

If you're on Velocity, you may also need to set login-ratelimit (velocity.toml) to 0
