Need something built?
Write me.

I take on a small number of commissions at a time so each one gets done right. Minecraft plugins, security focus, Folia-compatible by default.

Custom Plugin
Got an idea that doesn't exist yet? I build it from scratch. We scope it, agree on a price, and I ship it.
Security Audit
I go through your server setup and look for exploits, misconfigs, and known bypass methods.
Plugin Fix / Update
Something broken or running on an old API? Send it over. I patch, update, or rewrite whatever's needed.
All Plugins

What I've built.

Three plugins. All Folia-compatible. All on BuiltByBit.

AntiFreeCam
AntiFreeCam$9.99

Catches every freecam client and Block Entity ESP exploit I've come across. Silent, async, no main-thread impact.

AntiSeedCracker
AntiSeedCrackerFREE

Clients can calculate your world seed from just a few ore positions. This scrambles those calculations. Free.

AntiPearlGlitch
AntiPearlGlitchFREE

Pearl-glitching through walls and protected zones is a common bypass. Stops it per region, per world, however you want.

This antiCheat is the best I've ever seen in my life, I'm not joking. It prevents all methods of KryptonClient from working. Never causes lag — you can adjust everything from the config. Highly recommend.

★★★★★

Truly one of the few plugins that is not vibe-coded and actually works as the description says.

After testing several anti-freecam plugins on our Folia server, this one stands out. No lag, no tick spikes, even with many players online. Entity blocking feels instant and reliable. Highly recommended.

About me

Plugin dev. Network builder.

I'm Kayo. About two years writing Minecraft plugins, mostly security: freecam, seed leaks, pearl glitches. The stuff that actually ruins servers and nobody else fixes properly.

Three plugins on BuiltByBit, two full networks built from scratch with 20+ custom modules each. Everything async, everything Folia-compatible.
