What HetrixTools does
HetrixTools operates an uptime monitoring bot that visits websites when users subscribe them to the HetrixTools uptime monitoring service, repeatedly checking their availability. It identifies itself with the user agent "HetrixTools Uptime Monitoring Bot. https://hetrix.tools/uptime-monitoring-bot.html" and operates exclusively from IP addresses published on the HetrixTools monitoring nodes page. Site owners who do not want to be monitored can contact HetrixTools support to opt out or block the published IP ranges.

What is HetrixTools?
HetrixTools is a monitoring service whose uptime bot visits websites subscribed to the service to check whether they are up. The bot identifies itself with a user agent that begins "HetrixTools Uptime Monitoring Bot" and links to its documentation page.
Can I block HetrixTools with robots.txt?
The HetrixTools documentation does not describe any robots.txt handling; the bot is an uptime checker that visits URLs its users have configured rather than a content crawler.

About Operational Bots
Monitoring, security scanning, link previews, webhooks, and feed fetchers: the utility traffic that keeps integrations and shared links working.
Most of this traffic is service-critical or user-triggered. Webhooks and previews don't follow robots.txt, and blocking them tends to break things you rely on.
