The Ably Realtime Hackathon saw participants create realtime dashboards, collaborative experiences, and projects using React and other React ecosystem tools. Notable submissions include Ionic, a virtual lab environment for conducting chemistry experiments and exploring physics phenomena; Mood Tracker and Support Chat, an app that tracks patients' moods and provides health tips; and Cheat Inspector, which monitors online hackathons to ensure fairness. These projects demonstrate the potential of Ably in various sectors such as education, mental health support, and anti-cheating measures.
