Is Melty safe? What we can and cannot verify

Short answer: Melty publishes concrete safety rules, but in October 2026 there was no independent security review either confirming or clearing it. Here is both sides, with dates.

What Melty says

• Every release is audited. The Terms say the audit reads every file in a release (and its source code when published from GitHub), a release must first run on its creator’s PC, only releases that pass go live, and every update is audited again Melty Terms.
• Uploads are checked for dangerous files. The FAQ: “Every upload is checked for dangerous files. If a mashup looks wrong, report it from its page.” melty.gg FAQ
• Malware is banned. Creators may not publish malware, spyware, cryptominers or anything built to harm players, nor hide what a mashup does Melty Terms.
• Reports and takedowns. Anyone can report a mashup; Melty may remove mashups or accounts that put players at risk Melty Terms.
• Data. Melty says it doesn’t sell personal information or use it for advertising, stores coding-agent tokens hashed, and strips passwords, tokens, cookies and emails from crash reports Melty Privacy Policy.

These are the vendor’s own statements. We have not tested the audit.

What independent sources show

Gridinsoft (automated)

Risks that exist even if the app is honest

• Game file changes. The app writes into game folders and downloads third-party mod loaders and tools Melty Terms.
• Bans. Some games’ anti-cheat or online services don’t allow mods; Melty disclaims liability for game or account bans and lost saves Melty Terms.
• Your IP address. When you host a multiplayer game, your IP and port are shared with players who join; anyone with the invite link can join Melty Terms.
• Auto-updates. You agree to let the app update itself automatically Melty Terms.

How to reduce risk

1. Download only from melty.gg/download, never from re-uploads or look-alike domains.
2. Scan the installer with your own antivirus before running it.
3. Back up saves you care about, as the Terms advise Melty Terms.
4. Avoid mashups for online games with anti-cheat; stick to single-player titles.
5. Keep multiplayer invite links private unless you want strangers to join.
6. Report a mashup that looks wrong from its page melty.gg FAQ.
