Questions, answered

Is zerostack free to use?

Yes, but note the copyleft: it is GPL-3.0 licensed, so distributed derivatives must stay open.

Do I need an account to use zerostack?

No. It is a self-run project β€” clone it and run it on your own machine. Some features may optionally call external APIs; check the README.

Can I run zerostack on my own hardware?

Yes, that is the point. The code is public, so you can run, modify, and host it yourself.

How is zerostack licensed?

It is released under GPL-3.0. Read the LICENSE file in the repo for the exact terms.

Does it work without the internet?

That depends on the feature. Local-capable parts run offline; anything calling a cloud API needs a connection. Check the docs.
