CollabList is a real-time collaborative web application where multiple users can create, read, update, and delete items on a list. The list will be updated for every member of a list the moment one of them performs CRUD actions. The app is an excellent way for teams to efficiently and effectively collaborate on shopping lists, to-do lists, or any other forms of lists.
