The record

Product: mod.io is UGC middleware that helps game studios add mods and other user-generated content to games.
Features: Features include cross-platform support, in-game UI, multiplayer support, a marketplace, collections, metrics, dependencies, moderation, custom SSO, Cloud Cooking, an embedded hub, and a Discord bot.
Game engine integrations: The service offers Unreal Engine and Unity plugins, a C++ SDK for custom builds, and a REST API.
Desktop and mobile: The C++ SDK lists support for Windows, Linux, macOS, iOS, and Android.
Cross-platform reach: The documentation lists PC storefronts, PlayStation, Xbox, Nintendo Switch, Meta Quest, iOS, and Android as supported integration targets.
Moderation: UGC moderation includes automated scanning, rules-based moderation, optional content approval, and user reporting.
Security scanning: Uploaded UGC files are checked for viruses and malware, while text and files also undergo validation checks.
Image moderation limit: The documentation says mod.io does not currently apply AI or machine learning to detect inappropriate content in images; studios can connect third-party tools through webhooks.
Marketplace: Studios can enable premium UGC sales using virtual currency or USD pricing and configure revenue shares between creators and the studio.
Marketplace fees: The marketplace guide states that mod.io charges $0.0012 per virtual currency and that its web payment partner charges 5% plus $0.20 per transaction.
Marketplace security: The support page says Thunes processes marketplace transactions and describes annual third-party penetration tests, quarterly internal scans, FDIC-insured funds held in Thunes wallets, and SSL and PCI requirements.
Console access: Console support is described as a premium feature requiring an advanced service tier and approval from the relevant platform.
Support: The Unreal plugin installation guide directs users with questions to mod.io's Discord server.
Headquarters: Prahran, Victoria, Australia
