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.
