I'm using UptimeRobot (https://uptimerobot.com/) to monitor a number of sites. Websites in Webstudio are shown as offline even when they are online. According to their support it's likely that the IPs used by UptimeRobot need to be whitelisted.
This is more of a question rather than a suggestion. I don’t see it in roadmap but way way down the line, will there be some sort of Auth or method for gating content using Webstudio itself? For example password protecting pages.
