I might look at nsjail. I run chrome headless inside of cgroups (for cpu and memory restrictions) and using a runtime generated no-login user (for privilege restrictions), and with a custom group id (for IP tables bandwidth and routing restrictions). Plus I monitor the pool of chromes with a shell script and if any exceed a resource threshold, I used cpulimit then pkill to take care of it. I could just use docker (and I have docker images of this app that some people like to run) but I think this way is more lightweight, gives me more explicit control, and leans into the OS level security features, like privileges and cgroups with a couple of Unix commands.
