standalone
This is the easiest mode to spin a Selenium Grid. The server automatically picks up the drivers from the System PATH. All the RemoteWebDriver should point to the default grid URL.
Linux
$ echo $PATH
Windows
\> echo %PATH%

This is new mode introduced in Selenium 4 version. There are several grid components that needs to be started separately in this mode unlike in the standalone mode.
- Event-Bus
- SessionMap
