Dream Sports, a sports technology company, has launched HorizonOS, an open-source initiative to make its battle-tested, scalable tech platform available to India’s developer community.
HorizonOS will be a part of Dream Sports’ newly constituted SaaS business – Horizon.
The initiative will support start-ups and MSMEs across a wide range of sectors, including e-commerce, fintech, health-tech, etc.
HorizonOS will offer a host of functionalities, from tools to help developers build, test, and deploy faster, through core building blocks for application development to systems and platforms that allow those applications to run and be managed at scale. The software offered as a part of HorizonOS has helped solve real, complex problems at Dream11’s scale. Access to these core technologies can be a valuable addition to the open-source community and to India’s burgeoning startup ecosystem.
HorizonOS will be unveiled to developers for the first time at MumbaiHacks 2025, the world’s largest Agentic AI hackathon organized by TEAM and ‘Made in Mumbai’. Thousands of developers will get hands-on access to HorizonOS’ APIs, toolkits and foundational modules, allowing them to test ideas at scale.
Dream11 began its open source initiative with early contributions to open source projects such as ‘ReactNative’, ‘Kong’ and ‘Vert.X’. With HorizonOS, Dream11 aims to continue investing in free and open-source software.
Amit Garde, CEO, Horizon, said, “Open-source software forms the backbone of global innovation, and the Indian start-up ecosystem relies heavily on software built by the open source community. With HorizonOS, we are contributing back to the very community that helped us to successfully operate at the scale that we did.”
He added, “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.”
