Questions

Is the app different from the website? No — it is the same tool, kept on your device so it starts instantly and works offline.

Why don’t I see an install option? Firefox on desktop does not support installing web apps; use Chrome, Edge or Safari. If the app is already installed, the button is hidden.

How much space does it use? Usually a few megabytes per tool; larger tools such as the SQL Playground or PDF tools keep their engine on your device so they run offline.
