Is thunderstore.io legit or a scam?
Thunderstore is a real mod repository for Risk of Rain 2 and other games with occasional malware on subdomains.
These checks passed — but they don't clear the site. A clean antivirus result, valid SSL, and a calm server only mean it isn't hosting malware; they say nothing about whether the business is real. This verdict is based on the site's conduct and content, not a malware detection.
Analysis Summary
MT Intelligence
The page is a fully functional, professional mod database with listings, downloads, and integration with mod managers like r2modman. Our antivirus network showed only a single flag from CRDF while browser blocklists remained clean. The evidence package confirms it is the official site with an active GitHub organization, yet Malwarebytes documented malware uploads to certain subdomains. Positive long-term user feedback appears on Reddit and Steam, though four complaints and no public business registration were also noted. The combination of a clean main domain with known subdomain risks makes the site usable but not risk-free.
