Where does DayZDB get server data?

DayZDB discovers servers through Steam’s GetServerList API and refreshes details with the Steam A2S query protocol. Results are cached server-side. Visitors never talk to game servers directly and never receive the Steam API key.

Why are some fields Unknown?

DayZ only exposes some settings through public tags and rules queries. If a value cannot be verified, DayZDB shows Unknown or Not reported instead of guessing.

Are favourites saved to an account?

No. Favourites and recently viewed servers stay in your browser localStorage. They are not synced between devices and DayZDB does not require login.

How this browser works

Steam discovery + A2S refresh, cached for visitors — not a live query of every host on page load.

DayZDB pulls candidate servers from Steam’s public GetServerList API (AppID 221100), then refreshes details with UDP A2S_INFO and, when practical, A2S_RULES for mod payloads. The public site only reads a local cache through a rate-limited API. Your browser never receives the Steam Web API key and never opens arbitrary game-server sockets from DayZDB’s backend on demand.

Tags such as no3rd, mod, external, and battleye come from the server’s advertised keywords. If a setting cannot be verified, it is shown as Unknown. Player counts are as reported by the server and can be spoofed. Region/country values are approximate IP-based estimates when available.

Pair the browser with DayZDB’s CE types reference and XML Validator when you run your own mission files.

FAQ

Where does DayZDB get server data?: Steam GetServerList for discovery and A2S queries for refresh. Results are cached server-side on a schedule with controlled concurrency.
Why are some fields Unknown?: Public Steam/A2S data does not expose every DayZ setting. DayZDB does not invent values.
Are favourites saved to an account?: No. Favourites stay in localStorage on this device only. No login is required or offered.
How do I connect?: Open a server’s detail page for copy-IP actions and optional steam://connect using the query port. Prefer DayZ Launcher Direct Connect with the game port when listed.
