Chromebooks have obtained support for Family Link, the tool that Google rolled out to Android devices which lets parents more easily monitor their kid's device usage habits and manage that usage remotely from their own devices. Google doesn't appear to have made any sort of formal announcement that Family Link was being launched for the Chrome OS platform nor did it announce that Chromebooks would be getting the Family Link tool, however it did mention that there would be something available for parents to manage their kids usage on Chrome OS devices when it announced that it would be getting rid of the Supervised Users tool.
Much like Family Link on Android devices, on Chrome OS devices such as Chromebooks, with Family Link enabled there are a handful of things kids can't gain access to, such as the Play Store for downloading and installing new apps. The support page for Family Link on Chrome OS also notes that kids can be locked out of using Incognito Mode so they aren't able to hide their browsing history, and parents can also act preemptively by limiting the websites that their kids can browse in the first place.
It goes without saying that for parents to set things up they will need to make sure that the Family Link app is installed on the Chromebook they want to monitor and manage. This means that the Chromebook will also need to have access to the Play Store to get this app in the first place. So while there may not be much of an issue as most Chromebooks do have this type of access for apps, there are some which still don't so it's something to keep in mind. Since Google has made no official announcement on this it isn't clear if all or the majority of users will be able to see and install this app but it should be available to any user who has a machine that has Play Store access on that Chromebook.
