Yep, open-source (https://github.com/datamade/nyc-councilmatic) — tech leads DataMade used Python for open data scraping, Django & Bootstrap for responsive web app. There’s not currently an open API for Councilmatic’s city data, but if you’d like to email me, I can give you a sense of our plans: info at councilmatic.org.
