In a container
The latest version release is available as a docker image. To pull and run locally:
docker run --rm -p 8080:80 \
ghcr.io/scm-js/scm-js:latest
Then go to http://localhost:8080 in your browser.
Downloads
The desktop app consists of an electron wrapper around the editor with
some extra features: an auto updater (you may opt into the nightly
line from application preferences), automatic detection of Starcraft 1
installations, and native file association and 'open with...' support.
Nothing is signed yet, so Windows shows SmartScreen's warning and
macOS needs
xattr -d com.apple.quarantine before it will run.
| Platform | Latest release | Nightly |
|---|---|---|
| Windows installer | scmJS-windows-x64-setup.exe | nightly .exe |

All nightly builds are the same build as nightly.editor.scmjs.dev. Every asset, and the notes for each version, are on the releases page.
Other ways to run it
On your own web server
Every release has a scmJS-web.zip - this is the
built bundle, static files, with no server serve mechanism.
Unpack it anywhere that serves files from the root.
From source
Node required (22 or newer). Clone, npm install,
then npm run dev to run the development server or
npm run build:desktop for an installer.
It ships no game data
The tilesets, unit graphics and .dat tables are property
of Blizzard Entertainment and are not redistributable. On first run
the editor will present options to either Download them directly from
Blizzard or allow you to drop them in. Desktop builds will search on
disk to attempt to find the files.
If no game data is found, the editor will still function but fallback into a degraded state.
What it does
- Terrain Full isometric support, rectangle and single-tile brushes, flood fill, a pixel-accurate blend tool, symmetry, and terrain replacement across the map.
- Objects Draw units, sprites, doodads and locations using the games own graphics and idling animations.
- Triggers A classic editor, a classic trigger script SCMDraft option, and the briefing list, with an optional TypeScript-subset script compiler available as a plugin.
- Editing together Share the map you have open and send the link. Everyone who opens it edits the same map at the same time, each in their own editor, and sees the others' changes and pointers as they happen. Sharing takes a free scmjs.dev account; joining takes only the link.
- The file Every map file (CHK) section is kept in the order it found it, and only the ones you change are re-encoded. Protected and unusual maps are fully supported.
- Plugins scmJS has a sophisticated plugin system allowing for powerful extensions. Plugins for scmscx.com integration, map repair, walkability analysis, a painting tool and TrigScript, triggers written as TypeScript, are enabled by default. Browse Plugins to see more!
See the user guide for documentation.
Coming from StarEdit or SCMDraft
The layers, palettes and dialogs follow StarEdit and SCMDraft 2, so
the editor should feel familiar.
Triggers can be imported and exported as SCMDraft
.trg files with the text trigger editor plugin - this uses SCMDraft's TrigEdit syntax,
so triggers copied out of SCMDraft paste straight in.
