Observable 2.0 is being launched as an open-source static site generator that aims to help teams effectively communicate with data. While Observable notebooks are great for data exploration, they are not suited for polished dashboards and apps. Observable Framework fills this gap by allowing users to build data apps with interactive graphics using JavaScript on the front-end and any language for data preparation and analysis on the back-end. Framework offers customization options, a better developer workflow, and a better user experience. It also solves the problem of loading data by running data loaders on build for instant page loading. Framework is free and open-source, making it a versatile tool for data app development.
