Litematica for Minecraft 1.21.11 is release 0.26.16, paired with MaLiLib 0.27.20. Minecraft 1.21.11, released on December 9, 2025, was the last version of the old numbering system before Mojang switched to year-based versions (26.1 and onward). Its Litematica line is still actively the right choice for the huge number of worlds, servers, and modpacks built on 1.21.11 — and 0.26.16, published on the project’s Modrinth page on September 5, 2026, is its newest build.
This is also the version line where running an old build carries a specific risk, covered in the safety note below. The short version: always take 0.26.16 rather than an earlier 0.26.x or 0.25.x file from a download archive, and pair it with MaLiLib 0.27.20 — note that on this Minecraft version it is MaLiLib, not Litematica, that carries the 0.27 number.

Safety Note: Use the Latest 1.21.x Build
The Litematica project page on CurseForge carries a prominent warning about a severe vulnerability affecting the mod’s 1.21+ versions: on affected builds, connecting to multiplayer servers could expose players to malicious software, while single-player use was not affected. The project’s instruction to users is simple — update to the latest build. That is the version offered on this page: 0.26.16 is the newest release for Minecraft 1.21.11. If you have an older 1.21.11 jar in your mods folder (for example an early 0.26.x or a 0.25.x build kept from a modpack), replace it and its MaLiLib with the pair below rather than assuming all builds for the same game version are equal.
Download

Download MaLiLib 0.27.20 for Minecraft 1.21.11 (Modrinth)
Mirror copies: Litematica mirror · MaLiLib mirror. Site mirror (Terabox) — not an official link. The Modrinth release above is always the reference version.
Both buttons lead to the official Modrinth release files published by the Litematica project. You need both jars: Litematica will not start without the matching MaLiLib build in the same mods folder. The full version table for every Minecraft release is on the download page.
Installation Notes
- Java 21 for this line. Minecraft 1.21.11 runs on Java 21. Do not copy the Java 25 advice from the 26.x pages — each game line keeps its own runtime.
- Install the matched pair. litematica-fabric-1.21.11-0.26.16.jar plus malilib-fabric-1.21.11-0.27.20.jar in .minecraft/mods, unextracted, with no older Litematica or MaLiLib jar left behind.
- Mind the number swap. For 1.21.11, MaLiLib is 0.27.20 and Litematica is 0.26.16. Searching for “Litematica 0.27” lands you on the Minecraft 26.1.x page instead — a different game version entirely.
- Hotfix builds count. If you update from an earlier 0.26.x build, swap both jars even though the game version does not change, so the library stays in step with the mod.
- Verify in game. Press M for the Litematica menu and M + C for configuration. If the game stops at the loader with a dependency message, read which mod and version range it names — it is almost always a mismatched MaLiLib.
Why 1.21.11 Still Matters
Because 1.21.11 closed the old numbering era, it became a long-term anchor version: technical servers, redstone worlds, and modpacks that need stability tend to stay on it rather than chase every game drop. Litematica’s feature set on this line is complete — schematic capture and projection, the material list with its HUD, layer rendering, Easy Place, and the schematic verifier all work as documented, maintained on the official project by sakura-ryoko like the other current lines.
If you later move a world to the 26.x line, your .litematic files come with you: they sit in the shared schematics folder and load in the newer builds. What does not transfer is the jar pair — 26.1 and later each need their own Litematica and MaLiLib files, which is why each game version has its own page here.
One practical habit for this line: check which build you are actually running before asking for help or filing a report. The file name in your mods folder is the whole answer — if it does not end in 0.26.16 for Litematica and 0.27.20 for MaLiLib, you are not on the pair this page describes, and updating is a two-minute fix. Community support for masa’s mods almost always starts with those two file names, because so many loading errors, missing-menu reports, and verifier oddities trace back to a mixed pair rather than to the build itself.
Frequently Asked Questions
What is the latest Litematica version for Minecraft 1.21.11?
Litematica 0.26.16, released on September 5, 2026 on the project’s Modrinth page, with MaLiLib 0.27.20 as its required library. It is the newest build for the last Minecraft version of the old numbering system.
Is Litematica 0.26.16 safe to use on servers?
The CurseForge project page warns of a severe vulnerability in affected 1.21+ builds when connecting to servers, and instructs users to update to the latest version. Running 0.26.16 — the newest 1.21.11 build — with MaLiLib 0.27.20 is exactly that advice; do not play multiplayer on older 1.21.x jars.
Does Minecraft 1.21.11 need Java 21 or Java 25?
Java 21. Java 25 belongs to the newer 26.x game line (26.1, 26.2, 26.3). Each Minecraft line keeps the Java version it shipped with.
Why is MaLiLib a higher number than Litematica on this page?
The two mods version independently, and the numbers are not meant to match: for Minecraft 1.21.11 the correct pair is Litematica 0.26.16 with MaLiLib 0.27.20. Pair files by the Minecraft version in their names, never by similar-looking release numbers.
