Is Melty free to download?
Yes — the app is entirely free with no subscription. You still need to own the games you mash.
Download Melty (Free, Windows)
Melty is a free Windows app, and the only safe place to get it is the official site: melty.gg/download. This page explains what to expect from the download and install, and which “Melty download” links to avoid.
System requirements
- OS: Windows (Melty does not offer a Mac or Linux app; the mashups run the Windows versions of your games).
- Games: legitimate installed copies of whatever you want to mash — a wishlist entry is not enough.
- Disk space: enough for the mashup downloads on top of your existing games; mashups install alongside your games and uninstall cleanly.
What happens during install
Melty does not modify your games on install. It sits beside them as a launcher: when you press Play on a mashup, it downloads that mashup, patches what it needs, and launches the combined game. Uninstalling a mashup restores your original files — nothing permanent happens until you choose it.
Download links to avoid
- Mirror and “free premium” sites. Melty is free already, so anything offering a paid or unlocked version is re-hosting an unknown binary.
- “Melty Pro” or bundled installers. The official launcher ships from Stella Montis only; extra bundling is a red flag.
- Any link that is not melty.gg. Trending names attract impostors — the same pattern our safety review covers for mashup uploads.
First launch setup
After signing in, Melty scans your PC for installed games and builds your “My games” list — the pool that Create and Play draw from. Three things are worth doing before your first mashup:
- Confirm the game list is complete. Games installed on a different drive or through a launcher Melty did not detect may need a manual scan or re-detection from the app’s settings.
- Check disk headroom. Mashups download on top of your games; a few gigabytes of free space on the games’ drive avoids failed installs.
- Back up saves for games you care about. Mashups install alongside your games and uninstall cleanly, but any heavy modding is safer with a fresh save backup.
Updating and uninstalling
Melty updates itself through the app, and mashups update the same way — you always press Play on the latest version. Removing a mashup restores your original game files, and removing the Melty app itself does not touch your games: installs are reversible at both levels, which is the main safety difference from hand-editing game folders.
Frequently asked questions
Is there a Mac version?
No. Melty is Windows-only for now. Anything advertising a Mac Melty build is not the official app.
How big is the download?
The launcher itself is small; the heavier downloads are the mashups you choose to install, and those are handled inside the app with one click.
Does Melty work with Steam, Epic, or Game Pass games?
Melty works with installed PC games it can detect, and most store copies qualify once they are installed and launched at least once. What does not work: subscription-catalog versions that block file access, or cloud-only streams — mashups patch local files, so the game must exist on disk.
My antivirus flagged the installer — is that normal?
New launchers that patch game files sometimes trip heuristic warnings. The safe response is not to whitelist blindly: re-download from melty.gg, compare what you received against the file the official page lists, and only proceed from that official source. If a copy from anywhere else flags your antivirus, that is the warning working.
Can I use Melty on more than one PC?
Yes — install on each Windows PC you play on. Your published mashups live in your My mashups list, so other players (and your other machines) can play them once released.
