This article lists which systems can support which versions of Scratch.
Scratch 1.4 (offline only)
- Mac OS X – Compatible with Mac OS X 10.4 to macOS 10.14.6
- Windows – Compatible with Windows 2000 or later.
- Debian/Ubuntu/Linux Mint – Compatible with Ubuntu 12.04 (Precise Pangolin) or later.
- Mac OS X — a Mac with an Intel processor
- Windows XP or later
- GNU/Linux — Fedora 13, Ubuntu 10.10, or openSUSE 11.3 or later
- Requires Adobe AIR
The Scratch 2.0 Offline Editor can be downloaded at scratch:download/scratch2.[note 1] For macOS 10.10 and later or Windows 7 and later, the latest version of Adobe AIR may be downloaded here. For GNU/Linux and older operating systems, the AIR 2.6 runtime may be downloaded here. In the latter case, you must download the "Mac OS 10.5 & Older" version of Scratch.
There is also an online version of Scratch 2.0, which is compatible with all devices that support Flash Player 10.2 or later. A test to see whether a device has Flash properly installed is available here.
Until the release of Scratch 3.0, the online 2.0 editor could be found at projects:editor. This is no longer the case, but ScratchX, which is very similar to Scratch 2.0, or s2online, an unofficial version of Scratch 2.0, may be used instead.
- macOS (OS X) 10.10 or later
- Windows 10 or later[note 2]
- Chrome 63+ or Mobile Chrome 63+
- Edge 15+
- Firefox 57+
- Safari 11+ or Mobile Safari 11+
- Alternatively, a specific version of Scratch 2.0 may be downloaded from https://scratch.mit.edu/scratchr2/static/sa/Scratch-VERSION.exe (the version shouldn't have a "v" at the beginning, so for example version 451 has a URL ending with Scratch-451.exe).
- Despite not being officially supported, Scratch Desktop does work on Windows 7.
