About

What is Code4City?

Code4City is a one-day, high-impact hackathon organized by the Applied Urban Science Association. The event brings together students, professionals, builders, and urban thinkers to tackle pressing challenges facing cities today.

To accelerate the development phase, teams will be provided with mentors along with curated tutorials and guides designed to maximize impact within a limited timeframe.

Duration12 hrs with 8 hrs of build time
Team Size1 to 4 participants

Participants must submit a short project proposal during registration. Teams will be selected based on clarity, feasibility, and alignment with urban challenges.

Pro Tip Simpler explanations often resonate more with judges than complex technical descriptions. Focus on the "why" to make your proposal stand out.

Themes

Focus Areas and Technology

Participants must design solutions aligned with at least one of the following areas:
