It helps people take data of any shape or size and publish that as an interactive, explorable 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.

We also have [detailed installation instructions](https://docs.datasette.io/en/stable/installation.html) covering other options such as Docker. ## Basic usage datasette serve path/to/database.db This will start a web server on port 8001 - visit http://localhost:8001/ to access the web interface. `serve` is the default subcommand, you can omit it if you like. Use Chrome on OS X? You can run datasette against your browser history like so: datasette ~/Library/Application\ Support/Google/Chrome/Default/History Now visiting http://localhost:8001/History/downloads will show you a web interface to browse your downloads data: ![Downloads table rendered by datasette](https://static.simonwillison.net/static/2017/datasette-downloads.png) ## datasette serve options Usage: datasette serve [OPTIONS] [FILES]... Serve up specified SQLite database files with a web UI Options: -i, --immutable PATH Database files to open in immutable mode -h, --host TEXT Host for server. Defaults to 127.0.0.1 which means only connections from the local machine will be allowed. Use 0.0.0.0 to listen to all IPs and allow access from other machines. -p, --port INTEGER Port for server, defaults to 8001 --reload Automatically reload if database or code change detected - useful for development --cors Enable CORS by serving Access-Control-Allow- Origin: * --load-extension PATH Path to a SQLite extension to load --inspect-file TEXT Path to JSON file created using "datasette inspect" -m, --metadata FILENAME Path to JSON file containing license/source metadata --template-dir DIRECTORY Path to directory containing custom templates --plugins-dir DIRECTORY Path to directory containing custom plugins --static STATIC MOUNT mountpoint:path-to-directory for serving static files --memory Make /_memory database available --config CONFIG Set config option using configname:value docs.datasette.io/en/stable/config.html --version-note TEXT Additional note to show on /-/versions --help-config Show available config options --help Show this message and exit. ## metadata.json If you want to include licensing and source information in the generated datasette website you can do so using a JSON file that looks something like this: { "title": "Five Thirty Eight", "license": "CC Attribution 4.0 License", "license_url": "http://creativecommons.org/licenses/by/4.0/", "source": "fivethirtyeight/data on GitHub", "source_url": "https://github.com/fivethirtyeight/data" } Save this in `metadata.json` and run Datasette like so: datasette serve fivethirtyeight.db -m metadata.json The license and source information will be displayed on the index page and in the footer. They will also be included in the JSON produced by the API. ## datasette publish If you have [Heroku](https://heroku.com/) or [Google Cloud Run](https://cloud.google.com/run/) configured, Datasette can deploy one or more SQLite databases to the internet with a single command: datasette publish heroku database.db Or: datasette publish cloudrun database.db This will create a docker image containing both the datasette application and the specified SQLite database files. It will then deploy that image to Heroku or Cloud Run and give you a URL to access the resulting website and API. See [Publishing data](https://docs.datasette.io/en/stable/publish.html) in the documentation for more details.
