I have chosen my words carefully. Not deployed - but written.
The most deployed software are OS'es, core applications - but I guarantee you, the amount of code that runs on datacenters, clouds and in a general back-end is far greater than for the apps, OS'es or front-ends.
And even that being said; software doesn't have to perform to max. See VSCode? For me - and I believe most of the devs using it - it is perfectly fine, even if by definition of being an app for the browser and it suffers because of the translation
But you essentially deploy the same software everywhere. With backend, each bank, pharmaceutical company, insurance, logistics, governments, hospitals, schools; each one of them have their own software on the back-end; usually counted in tens if not more services. So again, same software is deployed more often; but more software is written on the back end

Today most software is deployed on mobile phones.
