NYC Core Framework

NYC Core Framework is a Bootstrap-based web framework with added design patterns and other components optimized for accessibility, translatability, usability, and clarity of presentation.

Quickly Go from Sketch to Production-ready Code

Skip the static mock-ups and design directly in HTML! Iteratively transition into developer-friendly code.

Out-of-the-box Accessibility Features

Put accessibility first with our pre-built components and examples, compliant with WCAG 2.0 AA standards.

Open Source and Customizable

Create anything with the help of a large community of developers and growing documentation.


NYC Core Framework is the product of hard work by team members from the NYC Gov Lab & Studio and DMI’s GIS unit at the City’s Department of Information Technology and Telecommunications (DoITT).
