Is 9Minecraft Safe? Reuploads, Ads and Where to Get the Same Mods Safely

Is 9Minecraft safe? I can't point to a documented malware case on it, and StopModReposts, the long-running blocklist of mod repost sites, doesn't tag it as malware. But I still wouldn't use it. 9Minecraft isn't where these mods come from. It's a repost site, and the problem is that you can't tell whether the file in front of you is the one the author actually made. You can look for the same mod on Modrinth, CurseForge or the author's own page, so there's no reason to take that gamble.

If you're a parent whose kid grabbed a few mods from it, don't panic. Keep reading for what to do next. And if your wider question is whether mods in general are a bad idea, I've got a separate piece on whether Minecraft mods are safe.

What 9Minecraft actually is

9Minecraft (9minecraft.net) is a big catalog of Minecraft stuff: mods, Bedrock add-ons, shaders, resource packs, maps, data packs, seeds, skins and more. When I looked in late October 2026 it also listed clients, including cheat-style ones like X-ray, and a few adult-themed mods. That's worth knowing if a kid is the one browsing.

The key point: the people who make those mods aren't the people running the page. Modders publish their work on their own pages. 9Minecraft collects copies of it. That's what the modding community calls a repost or reupload site.

Lookalike domains are a thing too. StopModReposts, the campaign that tracks these sites, lists several similar names (9minecraftmods.net, 9minecrafts.com, 3minecraftmod.com, kingminecraftmod.com and others), with notes like "Similar to 9minecraft.net" and "9minecraft.net clone." Check the address bar. Anything I say here is about 9minecraft.net only.

Why mod authors object to it

StopModReposts defines reposting as "the unauthorized re-uploading of (often copyrighted) files without the original author's permission." It lists 9minecraft.net on its blocked-sites list under the reason "Illegal redistribution." That's their label, not mine. Whether a copy is allowed depends on each mod's license, and some authors say no outright.

Vazkii, a well-known modder, names it directly on a page about mod reposts: sites like 9minecraft.net "are known for reuploading mod files without permission from the authors," and they carry a lot of ads, "to try to make money from mods they did not create." That page dates from 2017, so it's one modder's long-standing position, not a fresh audit.

Individual authors say it too. The CurseForge page for the Comfortable Nether mod has an FAQ question about redistributing the mod on other websites. The answer: "No. (Especially not 9Minecraft)"

That's the community's objection in a nutshell: the author never agreed to it, and the views and ad money from their work go to someone else.

Is 9Minecraft a virus?

First, the part in its favor. StopModReposts tags some sites on its list with a "Malware alert!" note. 9minecraft.net isn't one of them, and I haven't seen a scan or report showing 9Minecraft files carry malware either.

The risk is provenance. When you download from a repost site, you can't be sure the file matches the author's original. StopModReposts spells out the downside of reposting: users risk "downloading malware or outdated mod versions." Vazkii's list is similar: files for the wrong game version that crash, old or broken versions, and modified copies that could hide malware, plus data lifted by malicious ads. Those are general warnings about repost sites, not findings about 9Minecraft in particular. But they're the reason I'd rather skip any copy I can't trace.

Vazkii also warns that an "Official Download" label on a repost site can be misleading. A button that says official doesn't make it the author's file.

And there's the support problem. If a reupload breaks, the author can't help you. It isn't their copy.

If you already downloaded something from 9Minecraft

No need to panic. A few cheap steps are still worth doing:

1. Delete the mods you got there. Vazkii's advice is the same: remove them.
2. Run a malware scan with whatever security software you trust.
3. Change passwords if you ran anything that wasn't a normal mod file, like an installer or an .exe. A Java mod is usually a .jar file, not an .exe or a setup program.
4. Re-download the same mods from a proper source (next section).

If a family PC is acting up and you're wondering who to blame, take a breath. Mods from random sites are a known problem. That's not a kid doing something unforgivable, and the steps above are where to start.

Where to get the same mod safely

You don't need 9Minecraft to find a mod. Use it, if you like, as a list of names and get the file somewhere else:

1. Search the mod's exact name on Modrinth and CurseForge. I've covered whether Modrinth is safe and whether CurseForge is safe. Vazkii's page points to both as official places to download.
2. Check the author. The project page should show who made it. If the name matches what the mod's credits say, you're on the real page.
3. Match the game version and the loader. A CurseForge page lists game versions, mod loaders (Forge, Fabric, NeoForge, Quilt) and file dates. Pick the file that fits your setup.
4. Read the author's own notes. If their page says not to redistribute, a copy anywhere else isn't theirs.
5. Can't find it on either? Look for the author's own page or link. If there isn't one, I'd skip the mod.

That goes double for listings with 9Minecraft's name tacked on, like "OptiFine HD 9minecraft." That's a repost, not OptiFine's own download. Vazkii's page points to optifine.net for that one, and I've written about whether OptiFine is safe.

Playing on Bedrock instead? 9Minecraft lists add-ons too. For those, I've covered whether MCPEDL is safe, ad-link step and all.

So, is 9Minecraft safe to use?
