Datasette is a tool for exploring and publishing data. It helps people take data of any shape, 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, scientists, researchers and anyone else who has data that they wish to share with the world. It is part of a wider ecosystem of 46 tools and 157 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 follow the tutorial or take a look at some other examples of Datasette in action.

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

New: Datasette Desktop - a macOS desktop application for easily running Datasette on your own computer!

Latest releases

17th June 2024

datasette-faiss 0.2.1 - Maintain a FAISS index for specified Datasette tables

  • Pin to NumPy 1.x - the faiss-cpu library this depends on is not yet compatible with NumPy 2. #4

13th June 2024

datasette-cluster-map 0.18.2 - Datasette plugin that shows a map for any data with latitude/longitude columns

  • Fixed bug where default tiles were displayed at retina resolution in a way that caused the map labels to be illegibly small. #48

  • Switched from using GPT-4 Turbo to the new GPT-4o, which is half the price and should provide better results. #14

datasette-extract 0.1a7 - Import unstructured data (text and images) into structured tables

  • Now uses GPT-4o instead of GPT-4 Turbo - the new model is cheaper, faster and likely a little bit better too. #28

  • New llm logs -r/--response option for outputting just the last captured response, without wrapping it in Markdown and accompanying it with the prompt. #431
  • Nine new {ref}plugins <plugin-directory> since version 0.13:
  • llm-claude-3 supporting Anthropic's Claude 3 family of models.
  • llm-command-r supporting Cohere's Command R and Command R Plus API models.
  • llm-reka supports the Reka family of models via their API.

  • llm-fireworks supporting models hosted by Fireworks AI.
  • llm-together adds support for the Together AI extensive family of hosted openly licensed models.
  • llm-embed-onnx provides seven embedding models that can be executed using the ONNX model framework.
