BizPort Business Portal
BizPort is an open-source codebase that you can use to set up a business portal in any city. It was originally built for the City of Long Beach, California. You can visit their live version at bizport.longbeach.gov.
If you're a city staff member or strategist that wants to redeploy the site in your city, have a look at the guide to redeployment.
If you're a developer trying to set up BizPort on your own laptop or in production, check out the developer docs.
If you're a content editor learning how to edit copy in the content management system (CMS), the content editing docs are a great place to start.
BizPort is open source under the MIT License, which you are encouraged to read in its entirety here.
