What is Jason?

Jason lets you instantly turn any data, website, or API into your own custom app.


How does Jason work?

Jason works similar to a web browser.

While web browsers render websites from HTML,
Jason renders native apps from JSON markup.

All you need is a single JSON.
Your JSON is the app.


3 Steps to your own instant app!

  1. Write a JSON markup to tell Jason what to do.
  2. Load it in Jason.
  3. There is no step 3!
