Cobblemon vs Pixelmon: the actual difference
Both have turn-based battles. That is the misconception worth clearing first — people assume Cobblemon is the "casual" one because it looks like Minecraft, but it runs the Pokémon Showdown engine, which is the same competitive battle simulator the tournament scene uses. Cobblemon also lets you move freely during a battle, which Pixelmon does not.
The real difference is how much game comes in the box.
Pixelmon is a complete Pokémon RPG. Gym leaders, the Elite Four, NPC trainers, trading, breeding, held items, abilities, weather — built in, nine generations, 1,000+ species with detailed models. You install it and there is a game there. If what your group pictures is "Pokémon, but Minecraft", Pixelmon is the shortest route to it.
Cobblemon is Pokémon added to Minecraft survival. 851 species fully implemented as of 1.7.3, with data for all 1,025 (the ones without finished models show as substitute dolls and still battle). The art style matches vanilla deliberately. But there are no gyms, no Elite Four and no trainer NPCs in the base mod — that structure comes from addons, or from a pack that has already assembled them.
So the choice is not really "which is better". It is: do you want the RPG scaffolding built in, or do you want Pokémon that sit inside a normal survival world you can mod however you like?
Where Cobbleverse fits
Cobbleverse is the answer to "I like Cobblemon's style but I want the gyms". It is Cobblemon plus the adventure layer — progression, trainers and structure assembled into one pack, so you are not hand-picking addons and hoping they agree with each other.
It costs you two gigabytes for the privilege: 8GB minimum against Cobblemon's 6GB, because you are running a much larger mod list. On a server that is the difference between our 8GB and 10GB tiers, which is worth knowing before you pick.
Where All the Mons fits
All the Mons is a different animal. It is an All the Mods–scale kitchen sink — 400+ mods of tech, magic, storage and automation — that happens to have Cobblemon in it. You are not buying a Pokémon pack with some mods; you are buying a full ATM-class pack where catching things is one of several progressions running at once.
That is why it needs 10GB minimum and 12GB to be comfortable, the same as ATM10 itself. If your group's actual plan is "Pokémon", this is an expensive way to get there. If your group already loves kitchen-sink packs and wants Pokémon threaded through one, it is the only pack on this list that does that properly.
Loaders, and why it matters for your other mods
Cobblemon supports Fabric and NeoForge; the official pack ships Fabric. Pixelmon is NeoForge only.
This matters more than it sounds. A loader is not a preference, it is a hard boundary — a Fabric mod will not load on NeoForge and vice versa. If your group has a list of mods it refuses to play without, check which loader those are built for before you choose the Pokémon layer, because that choice is the one you cannot undo without rebuilding the server.
The practical shape of it: Fabric tends to have the performance and quality-of-life mods first; NeoForge carries more of the big content and tech mods. If you want Pixelmon, you are on NeoForge and that is settled.
Server-side: what actually costs you memory
Pokémon packs are entity-heavy, and entities are the thing that makes a Minecraft server work hardest. Every wild spawn is a living entity with AI, a model and a state the server tracks and broadcasts to everyone nearby. A hundred players' worth of Pokémon is a very different load from a hundred players' worth of cobblestone.
Three things follow from that, and they apply to all four packs:
- Spawn caps are your main performance dial. If the server feels heavy, lowering wild spawn density helps more than adding RAM. Adding RAM to an entity-saturated server mostly gives the garbage collector more room to be slow in.
- Player count moves the number more than the pack does. The table above is sized for a group of friends. A public Pokémon server with 30+ people needs the next tier up regardless of which pack you picked, because every player carries their own bubble of loaded chunks and spawns.
- CPU matters as much as memory. Entity AI runs on the main thread. A server with plenty of free RAM and a slow core will still stutter.
Our standard tiers scale CPU with RAM and the Premium tiers run on faster cores — on entity-driven packs that is one of the few places where the upgrade is doing something you can feel, rather than just raising a number.
Which one to pick
- You want gyms, the Elite Four and a Pokémon game, with the least setup → Pixelmon.
- You want Pokémon in a survival world that still feels like Minecraft → Cobblemon.
- You want Cobblemon's style with the RPG structure already assembled → Cobbleverse.
- You want a huge tech pack that happens to have Pokémon in it → All the Mons.
- Your group has a mod list it will not give up → check its loader first, then pick from what is left.
Every one of those is one click here — we pre-select the pack at checkout and install the loader, Java and the pack before you first join, so the decision above is the only one you actually have to make.
Frequently Asked Questions
Is Cobblemon or Pixelmon better for a server?
Neither is better outright. Pixelmon gives you a complete Pokémon RPG — gyms, Elite Four, trainers, 1,000+ species — with nothing to assemble. Cobblemon gives you Pokémon inside an ordinary survival world, in a vanilla-matching art style, with the RPG structure left to addons. Pick on which of those two experiences your group actually wants; the server cost is the same at 6GB minimum either way.
How much RAM does a Cobblemon server need?
6GB minimum and 8GB recommended for a group of friends. Cobbleverse, which adds the adventure layer on top, wants 8GB minimum and 10GB recommended. A busy public server should go a tier higher than whichever of those applies, because Pokémon packs are entity-heavy and player count drives the load more than the pack does.
How much RAM does a Pixelmon server need?
6GB minimum and 8GB recommended — the same range as Cobblemon, despite the larger species roster. Pixelmon's extra content is mostly data and models rather than additional mods running code, so it does not cost as much server memory as you might expect from the feature list.
Can Cobblemon and Pixelmon run on the same server?
No, and not only because of the loader. They are two separate implementations of the same idea, with their own species registries, battle systems and spawn logic. Running both would mean two Pokédexes and two sets of wild spawns competing for the same entity budget. Pick one.
Does Cobblemon have gyms?
Not in the base mod. Gyms, Elite Four fights and trainer NPCs come from addons, or from a pack that has already bundled them — which is exactly what Cobbleverse is for. Pixelmon has all of it built in.
Which loader should I use for Cobblemon?
Fabric, unless you have a reason not to. The official Cobblemon pack ships on Fabric 1.21.1 and that is the best-supported path. Use NeoForge only if the rest of your mod list is already built around it — in which case check that a NeoForge Cobblemon build exists for your Minecraft version before you commit.
