A Kotlin Mini Hackathon by Kotlin User Group Chennai

​Build. Ship. Demo.

​Get ready for a day of building, hacking, and shipping at Shipaton: Road to DevFest — Kotlin Edition — an in-person mini hackathon bringing together Kotlin developers, Android engineers, KMP enthusiasts, and builders from the Chennai developer community.

​Organized by Kotlin User Group Chennai, in collaboration with RevenueCat and GDG Chennai, with JetBrains as our partner.

​🌍 Part of Shipaton 2026

​This event is part of the wider Shipaton 2026 hackathon, a global online hackathon running through August and September 2026.

​Shipaton is all about building and shipping real apps. The Chennai edition is a local, in-person opportunity to build alongside the community, collaborate with fellow developers, and turn your ideas into something you can actually demo.

​You can participate in both the Chennai mini hackathon and the wider online Shipaton hackathon.

​Build your project with us on September 26th, continue working on it afterward, and submit it to the wider Shipaton hackathon before the submission deadline.
