Rest Sonar

Lightweight anti-bot connection protection for Minecraft servers and proxies, by Rest Studio.

Rest Sonar adds configurable pre-login filtering to reduce repeated joins and connection flooding.

Features

  • Per-IP 10-second and 60-second connection limits
  • IPv4 /24 and IPv6 /64 subnet protection
  • Global flood threshold and adaptive attack mode
  • Username-churn detection and temporary IP cooldown
  • Trusted-IP allowlist, state cleanup, and configuration reload
  • Admin commands: /restantibot status, reload, trust <ip>, untrust <ip>, unblock <ip> (also /restsonar alias)

Loader support

Velocity, BungeeCord, Waterfall, Bukkit, Spigot, Paper, Purpur, and Folia adapters are included in one JAR. Basic startup and command checks passed on selected QA servers; older Minecraft versions and the new rebranded beta still need live validation.

Limitations and setup

Install on the public-facing proxy when available. Backend servers need correct client IP forwarding. Adjust rate limits for shared NAT and Bedrock gateways. No CAPTCHA, VPN lookup, fake-server physics test, or network-layer DDoS protection is included.

Preview status: This version is a developer beta. Real login/flood and false-positive testing is incomplete. Use on test servers before production.
