## What it is
FastHTML is a Python web framework for building fast, scalable, interactive web applications with minimal code, mapping 1:1 to HTML and HTTP. It integrates HTMX for hypermedia-based interactivity and ships with built-in auth, database access, and styling, all extensible via pip-installable components.

## Use cases
- build an interactive web app in pure Python
- create a hypermedia app with HTMX without writing JavaScript
- rapidly prototype a full-stack website with auth and database
- serve HTML partials for dynamic page updates
- build a real-time collaborative drawing app
- write and run web apps inside Jupyter notebooks
- deploy a Python web app to Railway, Vercel, or Huggingface

## When to choose
- you want to build interactive web apps in Python with minimal boilerplate
- you prefer hypermedia/HTMX over JavaScript-heavy SPA frameworks
- you need built-in auth, SQLite database, and styling out of the box
- you want FastAPI-like ergonomics but returning HTML instead of JSON

## When to avoid
- you need to build a JSON REST or GraphQL API as the primary product
- your team requires a mature ecosystem of plugins and long-term stability guarantees
- you want a React/Vue-style client-side SPA architecture
- you rely on LLM coding assistants, which may not know FastHTML well
