Instant interactive calculations and recipe planners

Joining Servers & Port Semantics

Join

Verified servers appear in the in-game list; unverified ones are IP-direct only. Derives the actual UDP game port and the optional TCP query port without inventing any "join command".

Respawn Ticket & Wave Odds Simulator

Simulator

The official comment formula CI% = CI/(MTF+CI)×100%, both documented initial ratios side by side (24:14 / 24:18), step-by-step ticket gains for all nine event keys, plus the per-wave caps and time window.

Speed & Stamina Calculator

Calculator

Converts the human base speeds documented in the official template comments (walk 4.5 m/s, sprint 7 m/s) by the multiplier keys; sprint endurance is a linear estimate from the 5%/s drain, clearly labelled as such since the official regen is curve-based.

Server admin and config generation (7)

Config files, startup scripts and command wizards for running a server

Capacity & Stability Planner

Planner

Both RAM floors side by side (3096 / 4096 MB, neither official), the LocalAdmin auto-restart window (default 4 restarts / 480 s, with the counter-intuitive 0 and -1 semantics), log limits and tickrate notes; every increment is editable.

Port Matrix & Multi-Instance Planner

Ports

The UDP game port (dedicated = LocalAdmin CLI argument; port_queue is NONDEDICATED-only with a source-level 7777 fallback), the TCP query port = game port + query_port_shift and disabled by default, UPnP/dual-stack binding behaviour, and same-host multi-instance conflict detection.

Generate config →

Firewall Rule Generator

Firewall

ufw / firewalld / iptables / netsh flavours: the UDP game port is mandatory; the TCP query port is optional and comes with the source-level warning that it is disabled by default and exposes the RA password surface — never presented as required.

SteamCMD Deploy & Launch

Deploy

app_update 996560 (freetodownload, anonymous OK), LocalAdmin launch with both EULA acceptance methods, a systemd unit and a Windows bat; states the egg README's "NOT compatible with ServerMod2 or MultiAdmin" verbatim.

Generate config →

LocalAdmin Argument Builder

Startup

Tick through the official README argument table to build the command line: --restartsLimit/--restartsTimeWindow defaults and their 0/-1 semantics, the documented --noAutoFlush vs --noLogs incompatibility, both EULA acceptance routes, and the -- passthrough separator.

Generate config →

config_gameplay.txt Generator & Pre-checker

Config

Grouped generation on the current 14.x key set (cross-validated from three live configs, D3) as a full file or a diff-only fragment from one shared value function; the paste pre-checker names unknown/legacy/duplicate keys and never echoes the administrator_query_password value; any violation refuses the whole output.

Generate config →

config_remoteadmin.txt Generator

RA

SteamID64 members validated with BigInt (Number flips the verdict at the boundary); the 19-permission matrix (both D4 readings side by side, ServerConfigs flagged as source-only); badge colours limited to sourced values; override_password ships with the template's all-caps warning verbatim.
