WebWatchTowerBot
WebWatchTowerBot is the automated agent that Web Watch Tower uses to check whether websites are online and responding. If you found this page, you most likely saw our User-Agent in your server logs. This page explains what the bot does and how to recognise or allowlist it.
Our User-Agent
Every uptime check we send carries this User-Agent header:
Mozilla/5.0 (compatible; WebWatchTowerBot/1.0; +https://webwatchtower.app/bot)The version number may change over time, but the WebWatchTowerBot token and the +https://webwatchtower.app/bot reference will remain, so you can always match on the WebWatchTowerBot substring.
How the bot behaves
The bot sends lightweight HTTP(S) requests to the exact URLs that our customers have added for monitoring. It checks availability, response time, status codes, and related signals. Requests are low-volume and run on the interval each customer configures (typically once every 1 to 60 minutes). The bot does not crawl your whole site, submit forms, or attempt to log in.
Why you are seeing it
Someone with access to your website - usually you, your team, or your hosting provider - added it to Web Watch Tower to be notified if it goes down. Under our Terms of Service, a site may only be monitored by its owner or someone authorised to do so.
Allowlisting the bot
To make sure monitoring is reliable, allow requests whose User-Agent contains WebWatchTowerBot through your firewall, WAF, or bot-management rules. If you need to allowlist by source IP address instead, contact us and we will share our current egress ranges.
Blocking or reporting
You are free to block the bot at any time - it respects the response it receives and will simply report the site as unavailable to whoever is monitoring it. If you believe your site is being monitored without authorisation, please get in touch and we will investigate.
