Dream11 open-sources its tech stack that powered 300M users
What's the story
Dream Sports, the parent company of fantasy sports platform Dream11, has announced the open-sourcing of its technology engine. The move comes with the launch of HorizonOS, a software that will be part of Dream Sports' new Software as a Service (SaaS) business called Horizon. The announcement was made by Amit Garde, Senior Vice President of Engineering at Dream11 and CEO of Horizon.
Launch event
HorizonOS to be unveiled at MumbaiHacks 2025
HorizonOS will be officially launched at MumbaiHacks 2025, an AI hackathon scheduled for November 28 and 29 in Mumbai. The move comes as Dream Sports looks to diversify its offerings after a recent online gaming law disrupted its core business model. "Open-source software forms the backbone of global innovation," Garde said, adding that with HorizonOS, they are giving back to the community that helped them operate at such scale.
Developer support
HorizonOS to provide essential tools for developers
HorizonOS will offer a range of functionalities, from tools that help developers build, test and deploy faster, to core building blocks for application development. It also provides systems that allow these applications to run and be managed at scale. Over the past decade, Dream11 has grown rapidly with over 300 million users and peak traffic comparable to some of the world's largest real-time digital platforms.
Sectoral impact
HorizonOS to support diverse sectors
The initiative will support start-ups and small businesses across a wide range of sectors, including e-commerce, fintech, and healthtech. "All software applications require some foundational capabilities," Garde said. He added that they are making these building blocks available for individual developers, start-ups and MSMEs so they can focus on their core product proposition.
