An open source multi-tool for exploring and publishing data

PyPI Changelog Python 3.x License

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.

Try a demo and explore 33,000 power plants around the world, then take a look at some other examples of Datasette in action.

Then read how to get started with Datasette, subscribe to the weekly-ish newsletter and consider signing up for office hours for an in-person conversation about the project.

Exploratory data analysis

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.

Instant data publishing

datasette publish lets you instantly publish your data to hosting providers like Google Cloud Run, Heroku or Vercel.

Rapid prototyping

Spin up a JSON API for any data in minutes. Use it to prototype and prove your ideas without building a custom backend.
