C13 Modding Masters provides modifications and server-management tools for DayZ communities. Its catalogue includes mods featuring traders, quests, mutants, anomalies, territory zones, stashes and crafting, with both paid and free options. Server owners can purchase or access mods through an account linked to their SteamID, connect a server using a key, and manage settings through a web dashboard. Configuration is designed for mouse-based controls, including forms for map zones, traders and quests; saved changes can reach the server without a restart.

The platform also offers administrative features for managing players, servers, server slots, mod licences, purchases, payments and discounts. Owners can review mod instructions, files and updates, and send update announcements to Discord channels. Website chat support includes an AI assistant and an option to contact a person, while the site advertises 24/7 Discord support. C13 Modding Masters also presents SIGNAL, a DayZ launcher focused on game optimisation, crash assistance and a configurable interface, with support for partner servers.
