Private server talk is dense with shorthand that assumes you already know it. This glossary defines the terms we use across the tracker and our guides, in the order you are likely to meet them. Where a term has a whole guide behind it, the link is inline.
The basics
- Private server (pserver, "emu"). A World of Warcraft realm run by someone other than Blizzard, usually on a leaked or reverse-engineered game server. The engine that runs it is called an emulator.
- Realm. One game world on a network. A single project often runs several: one account, several realms, different rates and rules on each.
- Logon / realmlist. The line that points your game client at a project's servers. Setting your realmlist is the first step of playing anywhere. See how to start playing.
- Layering / sharding. Splitting one world into parallel copies to spread players. Vanilla purists often treat the absence of layering as a feature.
Numbers you will see everywhere
- Rates (x1, x5, x100). Multipliers on experience, and often on drop and gold too. x1 is "blizzlike" speed; x100 is a weekend. Most projects quote rates first because they set the whole feel of the realm.
- Blizzlike. As close to how Blizzard ran it as the team can manage: original rates, original mechanics, original content order. The opposite of a funserver. See our x1 blizzlike picks.
- Funserver. A realm built for speed and toys: boosted rates, strange items, instant progression. Not a slur here. It is a genre, and plenty of players only want that.
- Instant-60 / instant-80. A realm that hands you a max-level character so you skip levelling entirely.
- Progressive / progression (PTE). Content unlocks over time, patch by patch or raid tier by raid tier, instead of all being open on day one. TBC phase 3 is an example.
- Fresh. A realm wiped or started from zero so everyone begins on equal footing. Fresh launches are the biggest events in the scene; our launch calendar tracks the dated ones.
- Wipe. A full reset of characters and progress. A relaunch is usually a wipe plus a new season or ruleset.
Flavours of server
- Vanilla, TBC, WotLK, Cata, MoP, Legion. The expansion the realm emulates, which also decides the client version. WotLK dominates the tracker. See best Vanilla and best WotLK.
- Vanilla+ / Classic+. A Vanilla frame with new content, changed classes, or new systems bolted on. See the Vanilla+ hub and what Classic Plus means.
- Classless. No fixed classes. You pick abilities from every class and build your own. See Ascension's classless model, explained.
- Hardcore / permadeath. One death ends the character. See the hardcore roundup and WOW Hardcore in the tracker.
- RP and RP-PvP. Roleplay and roleplay with open PvP, where staying in character is part of the ruleset. For the wider category, see the PvP picks.
- Cross-faction. Horde and Alliance can group, chat, or trade. Common on small realms because it doubles the available group pool.
How small realms fake a crowd
- Playerbots / PartyBots / altbots / BattleBots. Server-run AI characters that fill groups, level alongside you, or fight in battlegrounds. These are the reason a realm with 40 real players can still run dungeons. See playerbots vs PartyBots vs scaling and playerbot architecture, explained.
- Scaling. Content that adapts its difficulty to your group size, the other way small realms make group content work. See solo scaling, explained.
Money and fairness
- P2W (pay-to-win). A shop that sells power: gear, levels, or advantages a non-paying player cannot match. See who sells power and who sells cosmetics.
- Cash shop / donation shop / store. Where a project takes money. A well-run one sells cosmetics, mounts, or convenience and nothing that decides a fight. A donate bar that "buys nothing" is a claim worth checking.
- Whale. A single player who spends far more than average. Shops that chase whales are the ones that tend to drift toward power sales.
The machinery underneath
- Core. The emulator a project is built on. AzerothCore and TrinityCore are the WotLK mainstays; VMaNGOS and CMaNGOS carry Vanilla and TBC. The core decides how much of the game works, and which bugs a team inherits. See what a core actually is.
- Client versions. 1.12 is Vanilla, 2.4.3 TBC, 3.3.5a WotLK, 3.4.x the modern Wrath Classic client, and later numbers map to later expansions. A "3.3.5a" realm and a "3.4.x" realm can feel very different for the same expansion. See 3.3.5a vs the modern client.
- Scripting quality. How faithfully quests, dungeons, and mechanics behave. It is the single hardest thing to judge from a website, which is why we read the realm before listing it.
- Armory / database (DB). A web view of characters or of every item and quest in the game, usually a sign of a serious project.
Events, numbers, and terms of art
- PTR / OBT / CBT. Public test realm, open beta test, closed beta test. A project in testing is not a launch, which is why our calendar separates verified launches from announced ones.
- C&D (cease and desist). A legal demand, usually from Blizzard, that ends a project. It is the dominant cause of death on the tracker now. See the 2026 crackdown and the shutdown roundup.
- Toplist. A voting directory sites use to rank servers. It measures votes, not players. See votes are not players.
- Discord activity. A count of how many members are active in a server's Discord. It describes the community, not the number of people logged into the game, and the two can be wildly apart. We keep them separate, which is why more than half the tracker carries an unknown population band rather than a guess.
- Uptime. How long the server process has been running without a restart. A high number is a modest sign of stability; a very low one can just mean a routine restart. See what a build number does not tell you.
- Population band (popTier). Our own label, tiny to large, applied only when a project publishes a counter we can name. Where it does not, we say unknown. See the census on why that is the honest number.
How we use these words
Two habits sit behind this glossary.
- We do not upgrade a claim to a fact because a listing site repeats it. A directory's "online" tag is a claim; the project's own status page is evidence. Where we only have the claim, we say so. Our correction policy explains the rest.
- We date everything. A population band or a status without a date is not worth much, because this scene changes weekly.
If a term you have seen in the wild is missing here, it is a candidate for the next pass.
