Session length is capped by plan (2 to 60 minutes) versus no limit on Sandboxer paid plans.
Billing counts connection time in 30-second units, not machine size.

Pick Browserless if

You run high-volume scraping with stealth, proxies and captcha handling.
You need a self-hostable or on-prem browser fleet under a commercial license.

Pick Sandboxer if

You need a full Ubuntu VM with root, systemd and Docker rather than a browser instance.
You want stop/resume that keeps running processes, or CoW forks of a disk snapshot.
You want coding agents preinstalled and any port exposed as an HTTPS URL.
