What software do you use daily in 2026?

There was a similar thread here six years ago, and I'm curious how people's daily setups have changed since then. What does the software side of your daily setup look like in 2026? Operating system, desktop environment or window manager, terminal, shell, editor, browser, and any other tools you consider essential to your daily workflow. I'm especially interested in the small or less obvious tools that have become indispensable to you.
