## What it is
Observable Framework is an open-source static site generator for building data apps, dashboards, and reports. It combines reactive JavaScript on the front-end with data loaders in any back-end language (SQL, Python, R) that precompute data snapshots at build time for instant-loading pages.

## Use cases
- build interactive dashboards from code
- create data apps with charts and reports
- generate static sites from markdown with embedded visualizations
- precompute data snapshots at build time for fast dashboards
- write data analysis in Python, R, or SQL and render it in the browser
- build reports with D3, Observable Plot, and Vega-Lite charts
- host fast-loading data dashboards on any static hosting

## When to choose
- you want code-driven dashboards with instant page loads
- you prefer markdown plus reactive JavaScript for data apps
- you need to mix back-end data analysis languages with front-end interactivity
- you want to version-control and CI/CD your dashboards as plain files

## When to avoid
- you need a fully dynamic server-rendered application with per-request data
- you want a no-code dashboard builder
- you need real-time streaming data updates in the browser
