MCA Selector is free, open source and very good at its specific job — bulk chunk operations on Java Edition worlds. But there are jobs it does not do at all: it cannot open a Bedrock world, it has no 3D building mode, it does not run inside the game, and it is not a raw file editor for player data. This page collects the realistic alternatives, says plainly what each one is for, and corrects one tool that is constantly mislisted as an editor.
Amulet Editor — for 3D editing, conversion and Bedrock
Amulet is the modern all-round world editor: copy, paste, fill, replace and delete inside a 3D view, and convert worlds between Java 1.12+ and Bedrock 1.7+ versions and editions. It is the alternative to reach for when your world is Bedrock, when you need conversion, or when you want to place blocks rather than manage chunks. The trade-off: compiled builds cost $10+/year (the source can be built yourself), against MCA Selector’s free MIT download. Full comparison: MCA Selector vs Amulet Editor. If your question is specifically about Bedrock, start with does MCA Selector work with Bedrock.
WorldEdit — for building inside the game
WorldEdit is a free mod/plugin (GPLv3) that works in a running Java world: copy and paste structures, fill volumes, brush terrain with commands and selection tools, all visible in 3D immediately. It is the alternative when the work is live building or in-game server administration. It does not do offline, whole-world chunk maintenance — that remains MCA Selector’s territory. Full comparison: MCA Selector vs WorldEdit.
NBTExplorer — for raw NBT in single files
NBTExplorer is a free, MIT-licensed tree editor for NBT files: level.dat, player data, region files, schematics. No map, no bulk chunk selection — instead, direct access to every tag in the one file you open. It is the alternative when your problem is a player’s data file or a world setting rather than a thousand chunks. Full comparison: MCA Selector vs NBTExplorer.
Chunky — not an editor at all (and that is fine)
Chunky appears in “best Minecraft editors” lists surprisingly often, and it does not belong there: Chunky is a path-tracing renderer (free, GPL-3.0) that turns a Java world into realistic images. It cannot change a single block. If what you actually want is a beautiful render of your world — for a server page, a video thumbnail, a poster — Chunky is an excellent tool, and it pairs well with MCA Selector rather than replacing it: prune the world first, then render it.
MCEdit — the old name in older guides
Many older tutorials still point at MCEdit, the classic 3D editor of an earlier era. Treat it as a legacy reference when you meet it in old guides; the current choices for new work are the tools above. If an old guide tells you to do a bulk chunk job in MCEdit, the same job today is a filter-and-delete pass in MCA Selector, covered in our beginner’s guide.
A word of caution about “online MCA editors”
There is no official web-based MCA Selector: the tool is a desktop download from its GitHub project, and the project author has publicly flagged an impersonation site. If a page offers an “online MCA editor” under the project’s name, do not upload your world to it. Our online and mobile versions page explains what does and does not exist.
Alternatives at a glance
| Tool | Best for | Price / licence |
|---|---|---|
| Amulet Editor | 3D visual editing, Java↔Bedrock conversion, Bedrock worlds | Compiled builds $10+/year |
| WorldEdit | Building and terrain work inside a running game or server | Free / GPLv3 |
| NBTExplorer | Hand-editing NBT in single files (player data, level.dat) | Free / MIT |
| Chunky | Rendering a world as a realistic image — not editing | Free / GPL-3.0 |
| MCA Selector | Bulk chunk delete/reset/export and batch field edits on Java worlds | Free / MIT |
Whichever tool you pick, back up first: world tools change your save files directly. Close Minecraft (and stop your server, if the world is on one), copy the whole world folder somewhere safe, and only then start editing.
Download MCA Selector 2.9
If MCA Selector is the tool that fits your job, get the current release from the MCA Selector download page — the Windows installer, the cross-platform .jar, the macOS .dmg and the Linux .deb/.rpm, every button pointing at the official GitHub release files with the SHA-256 checksum listed, plus a clearly labelled site mirror as a fallback. It is free and open source under the MIT licence.
One last backup reminder: keep the copy of your world you made before editing until you have loaded the edited world in Minecraft and confirmed it looks right. Deletions and NBT changes in MCA Selector are permanent once applied.
