Minecraft Data Packs: How to Install Them and 7 Good Ones to Try

Last updated 9 October 2026. Checked against Java Edition 26.3 and Bedrock 26.x. Pack versions below come from each pack's own project page and were checked on 9 October 2026. Packs update often, so look at the page before you download.

What is a Minecraft data pack?

A data pack is a collection of files that tells the game how to behave. It is a folder, or a .zip file, with a pack.mcmeta file in it. Data packs can define advancements, recipes, loot tables, structures, biomes and enchantments, and run command functions. They can't add new code, so they can't give you brand-new models, mobs with their own animations or new block types the way a mod can. That is why data packs are lighter than mods and still work with a vanilla client.

On Bedrock, the nearest thing is the add-on system with behaviour and resource packs. Data packs and add-ons don't work on each other's editions.

How to install a data pack

In singleplayer

1. Download the pack as a .zip file. Don't unzip it unless the page tells you to.
2. For a new world, open More on the world creation screen, choose Data Packs and drag the .zip in. For an existing world, choose Edit, then Open World Folder, and put the .zip in the datapacks folder.
3. Type /datapack list in the world. Your pack should be under the enabled packs. If it is listed as available only, run /datapack enable "file/PackName.zip" with the exact file name.

On a server

1. Stop the server and take a backup (how to back up your server).
2. Upload the .zip into world/datapacks with the panel's Files page or SFTP (connect with SFTP). If your world folder has a different name, look at level-name in server.properties.
3. Start the server, or, if it is already running, type /reload in the console. Reload picks up recipes, loot tables, advancements and functions. Anything else, including world generation, needs a restart.
4. Type /datapack list to check the pack is enabled.

For a pack that changes world generation, such as the biome packs below, put it in before the world generates: stop the server, create world/datapacks yourself and upload the pack there, then start the server on a new world. A world generation pack only shapes chunks that don't exist yet, so chunks you've already explored keep their old terrain.

Why does a pack say it is for a different version?

Every data pack declares the data pack format it was written for in its pack.mcmeta, and every Minecraft version has a format number. If they don't fit, Minecraft shows a warning when you enable the pack. Since 1.21.9 the format has a major and a minor number (for example 88.0), and a pack says which range it supports with min_format and max_format, where older packs used a single pack_format number. The Minecraft Wiki lists these data pack formats for recent releases:

You don't need to edit these numbers. Download the build made for your Minecraft version, which the pack's download page labels. Changing a number in pack.mcmeta by hand can make an old pack load, but the pack may still break because the game changed underneath it. See the Pack format page on the Minecraft Wiki for the full table.

Seven real data packs for Minecraft 26.x

All of these are free, work on a vanilla server and are updated regularly. Each entry says what the pack does (from its own page), what we found on 9 October 2026, and one thing to know before you install.

Vanilla Tweaks

Not one pack but a pick-and-mix site: you choose small tweaks from a list and download them as a single data pack. Checked 9 October 2026: the Vanilla Tweaks data pack picker offers versions 26.1, 26.2 and 26.3. Practical note: choose your Minecraft version first, because the available tweaks change from version to version, and read what each tweak does before you tick it.

Terralith

A world generation overhaul that adds over 95 new biomes and updates most vanilla ones, using only vanilla blocks, with new structures to match. Terralith on Modrinth. Checked 9 October 2026: data pack build 2.6.5 for 26.3, published on 27 September 2026. Practical note: the page warns that you can't remove Terralith from an existing world, and it recommends starting a new world rather than adding it to an old one. Its Fabric and NeoForge mod builds differ from the data pack build, so don't swap between them in one world.

Tectonic

Reshapes the terrain: continent-sized landmasses, deeper oceans and very large mountain ranges, with no new blocks. Tectonic on Modrinth. Checked 9 October 2026: data pack build 3.0.29 for 26.3 (22 September 2026), though the page says its fully supported versions are 1.21.1 and 26.1. Practical note: to combine it with Terralith, use the special Terralith-compatible version the page links to, rather than installing both normally.

Incendium

Rebuilds the Nether with 8 new biomes, 9 or more structures, custom weapons and tougher mobs. The project is now called Incendium Legacy. Incendium on Modrinth. Checked 9 October 2026: data pack build 5.5.3 for 26.3, published on 28 September 2026. Practical note: the page says not to add it to an existing Nether. Reset the Nether first, or use a new world.

Nullscape

Turns the End into an alien dimension of strange terrain and a couple of new biomes, but keeps it empty and bleak. Nullscape on Modrinth. Checked 9 October 2026: data pack build 2.0.1 for 26.3, published on 28 September 2026. Practical note: the page says not to add it to an End you have already visited. Reset the End first, or use a new world, and don't combine it with other End generation packs.

Dungeons and Taverns

Adds vanilla-style structures to find while exploring: taverns, watch towers, dungeons and more. Dungeons and Taverns on Modrinth. Checked 9 October 2026: data pack build 6.0.2 for 26.3, published on 1 October 2026. Practical note: its page warns about a fake website that hosts malware. Download only from the creator's Modrinth or CurseForge pages.

Towns and Towers

Adds new villages, pillager outposts and ships to the world. Towns and Towers on Modrinth. Checked 9 October 2026: the data pack build is labelled for 26.1 to 26.2 (30 June 2026), while the Fabric and NeoForge builds are version 1.13.12 for 26.3. Practical note: for a vanilla 26.3 server, check that a data pack build for 26.3 exists, or use the mod version on a Fabric or NeoForge server.

Not on the list: mods that people often call data packs, such as Epic Fight, TerraForged and Custom NPCs. They are mods, so they need a loader and the same files on every client.

How to uninstall a data pack safely

1. Back up first. Take a full copy of the world (on a GTX server, a backup from the panel) before you disable anything.
2. Run /datapack disable "file/PackName.zip", then stop the server or close the world.
3. Delete the .zip from datapacks, then start again.

Packs that only change recipes, loot or advancements come out cleanly. Packs that changed world generation can't be fully undone: chunks that already generated keep the terrain, biomes and structures of the pack, and Minecraft may log errors or show seams where they meet new chunks. Terralith's page says outright that you can't remove it from an existing world. If you want to go back, restore your backup or start a new world.

If a world won't open after a pack change, Minecraft offers a safe mode that opens the world with every data pack off. Use it to get a backup, and don't save over your only copy.

Using data packs on a GTX server

A data pack is one of the cheapest ways to change a server, because players join with an unmodified game. Upload the pack as shown above, check /datapack list, and tell your players what changed. For mods that need a loader and the same files on every client, see our Minecraft server guide, and for the hosting itself, our Minecraft server hosting installs a new version or modpack from the panel (installing a modpack). Data packs don't work on a Bedrock server: see Bedrock server hosting for add-ons.

Data packs FAQ

Do data packs work on Bedrock Edition?

No. Data packs are for Java Edition only. Bedrock uses behaviour packs and add-ons.

Do players need to install a data pack?

Not for a pack that lives on the server or in the world: it works for everyone who joins with a vanilla game. Some packs come with an optional resource pack for textures, such as Incendium's Sparkles pack.

Can I use data packs on a Realm?

Yes, but not directly: you add the pack to a singleplayer world and upload the world to the Realm. Our Realms mods guide has the steps.

Why does my pack do nothing after I upload it?

The usual causes are a pack in the wrong folder (it must be directly in world/datapacks), a .zip with an extra folder around the real pack files, a pack built for another Minecraft version, or world generation changes in chunks that already exist. Run /datapack list to see whether the game loaded it.

Are data packs the same as mods?

No. A mod runs code and needs a mod loader. A data pack only changes data the game already knows how to read, so it stays vanilla-compatible.
