This page loads the same three tables the Mac app downloads and runs the same routing rules over them. The prices are real and there is no account. It cannot reach into your machine, so the rows that need that are labelled.
This is running in the tab, against the same tables the Mac app uses.
Celeritas downloads three tables to your machine and answers out of them. They are public files on celeritylabs.co, so this page fetches the same ones: coins every fifteen minutes, currency hourly from 98 central banks, shares at the previous close.
Working out which path should answer a query is its own piece of logic, and the app repository holds a 52 case spec for it. The version running on this page is checked against that spec and passes all 52.
A browser cannot read your calendar, open an app or check your battery, so those rows say so where the answer would be. A question that needs a model shows which model would take it and sends nothing. All of it works once the app is on your Mac.
Mail, files, calendar, reminders and system settings, from the same keystroke. Free, MIT licensed, 4 MB. The product page carries a checksum and a virus scan if you want to check the download before you open it.
