How can anyone run access Selenium test scripts without having to install/run it locally?

I am looking for ways to set up like a central 'hub' for Selenium in my work, allowing anyone to access in within the company. For example, Tester A writes test scripts, the Person B can run without having to manually copy over the test scripts to their local workstation)

So far, I've only thought of installing Selenium in a VM which will then execute as per normal. But if I run Selenium Grid, it will run VMs within VM (?). My only concern with VMs is that it'd run slowly.

If anyone can think of a better solution or recommendation please do give me some advice. Thank you in advance.
