How Airglow identifies it
- DeclaredIt names itself in the User-Agent:
meta-externalagent.
Every visit in Airglow says which of these applied, so you can decide how much to trust it.
Seeing it on your site
It usually reads pages without running JavaScript, so Airglow counts every visit through a server connection (Cloudflare). When it does run JavaScript, the script sees and replays it too.
Allowing or blocking Meta external agent
Meta external agent reads the meta-externalagent group in your robots.txt. To keep it out of the whole site:
User-agent: meta-externalagent Disallow: /
Meta runs a separate bot for each purpose, so blocking Meta external agent doesn't block its other agents listed below.
Airglow shows, for every agent that visits, whether your robots.txt lets it in, and helps you write rules by purpose (training, search, acting for a person).
