Overwolf

Overwolf is an Israeli company that operates a platform for building, distributing, and monetizing in-game apps and mods. The platform is used by third-party developers to create overlays and tools that run inside PC games, and by game publishers to offer modding ecosystems to their player communities.

Overwolf's primary offering is a desktop SDK and app store specifically for in-game software — overlays, stat trackers, coaching tools, and mods that run alongside PC games without requiring players to alt-tab out. The platform serves two distinct audiences: independent developers who build and publish apps through Overwolf's distribution network, and game publishers who embed Overwolf's modding infrastructure directly into their titles under a white-label arrangement called CurseForge. CurseForge, originally a Curse/Twitch-era mod repository that Overwolf acquired, is the largest mod-hosting platform for games including Minecraft and World of Warcraft. Developers on the platform can earn revenue through Overwolf's built-in advertising and subscription tools.

The two main products are the Overwolf App Platform, which handles in-game overlay apps, and CurseForge, which handles mod hosting and distribution. CurseForge was acquired by Overwolf from Twitch (Amazon) and serves a large community of modders and players across titles such as Minecraft, World of Warcraft, and The Sims. In 2022, CurseForge made headlines when it was involved in a security incident in which malware was distributed through compromised mod author accounts, affecting the broader modding community.

Overwolf operates in the in-game tools and modding infrastructure space. Its closest comparable is arguably Nexus Mods, a competing mod-hosting platform, though Nexus Mods focuses on a different set of titles and operates independently. CurseForge's integration with major titles like Minecraft gives Overwolf a structural distribution advantage in that segment.
