Dream Sports, the parent of fantasy gaming platform Dream11, said it has launched HorizonOS, an open-source version of the technology stack that helped the company scale to over 300 million users.
The move is aimed at making its internal infrastructure available to developers and startups across sectors such as ecommerce, fintech and healthtech.
According to the company, HorizonOS will offer a set of tools and foundational modules that allow developers to build, test and deploy applications, along with systems that help apps run and scale reliably.
“All software applications require some foundational capabilities. We are making these building blocks available for individual developers, start-ups, and MSMEs to use so they can focus on solving for their core product proposition,” Amit Garde, CEO of Horizon, said in a blog post.
Dream11’s internal engineering components, now being open-sourced, were used to address large-scale technical challenges at the company, which currently handles peak loads of 16 million concurrent users and around one lakh transactions per second.
Dream Sports said the decision to open-source parts of its tech stack follows the enactment of the Promotion and Regulation of Online Gaming Act, 2025, which significantly impacted its real money gaming (RMG) business, and is part of its broader attempt to contribute to the developer ecosystem.
The company has previously contributed to open-source projects such as ReactNative, Kong, and Vert.X. It said HorizonOS will continue investing in free and open-source software.
Dream11 has been undergoing major changes after the new gaming regulations enforced a blanket ban on its RMG operations. The platform, in September, said it is monetising through advertising and sponsorships, offering brand-backed prizes for free contests.
Earlier this week, its CEO and cofounder, Harsh Jain, said the company will shift its corporate office from Bandra Kurla Complex (BKC) to Worli in January 2026 as part of its ongoing cost-optimisation efforts.
