Datasette is an app that you run from the command line. You just point it to a SQLite database and run datasette mydb.db. And what it does is set up a simple, secure, publicly-available read-only web application for exploring that data. That’s basically it. It takes database files and makes them really easy to explore on the Web

I agree completely with Paul’s take. Datasette feels like a simple idea that will end up being an important one.
