HackGreenwich is a fast-paced, beginner-friendly hackathon hosted at the Greenwich Library, where creativity, problem-solving, and collaboration come together in just 3 hours.

Participants will work individually or in small teams to design and build a project that addresses a real-world problem or explores an innovative idea using technology. Whether you’re into coding, design, AI, hardware, or just brainstorming creative solutions, HackGreenwich is a space to learn, experiment, and build — no prior hackathon experience required.

What makes HackGreenwich special is its short, high-energy format. Instead of an all-night event, hackers focus on rapid ideation and execution, making it perfect for first-time hackers and busy students. Mentors will be available throughout the event to help teams troubleshoot, refine ideas, and stay on track.

Event Schedule (3 Hours):

  • Welcome & rules overview

  • Team formation & ideation

  • Hacking time

  • Project submissions

  • Demos & judging

Come build something cool, meet new people, and challenge yourself — all in one afternoon at the library.
