Annotated version of this introductory video
Datasette is a tool for exploring and publishing data. It helps people take data of any shape or size, analyze and explore it, and publish it as an interactive website and accompanying API.
Datasette is aimed at data journalists, museum curators, archivists, local governments and anyone else who has data that they wish to share with the world. It is part of a wider ecosystem of tools and plugins dedicated to making working with structured data as productive as possible.
Import data from CSVs, JSON, database connections and more. Datasette will automatically show you patterns in your data and help you share your findings with your colleagues.
datasette publish lets you instantly publish your data to hosting providers like Google Cloud Run, Heroku or Vercel.
Spin up a JSON API for any data in minutes. Use it to prototype and prove your ideas without building a custom backend.

sqlite-utils 3.6 adds similar features: a
db.attach(alias, filepath) Python API method and
--attach alias filepath.db command-line option, both for attaching additional databases in order to execute cross-database queries.
