Recognise the bot

User agent

OutseenBot/1.0 (+https://outseen.io/bot)

Previous name of the Quickscan, moving over to OutseenBot:

OutseenQuickscan/1.0 (+https://outseen.io/quickscan)

Requests are signed with Web Bot Auth (RFC 9421, Ed25519). The Signature-Agent is https://outseen.io; the keys are in the key directory:

https://outseen.io/.well-known/http-message-signatures-directory

The bot runs on Cloudflare Workers. There is no fixed list of IP addresses, so verify the signature instead.

What the bot does

  • Atlas fetches websites for technical SEO and AI visibility checks: in the free Quickscan, only when a visitor asks for it, and in measurements for clients of their own website.
  • It works at a calm pace. In the Quickscan it fetches at most about 30 pages per scan and runs at most one scan per domain per hour.
  • It does not fill in forms, log in or buy anything.

robots.txt

The bot follows robots.txt (RFC 9309) and respects a Disallow for OutseenBot or for *. For now it also respects the older names OutseenQuickscan and OutseenAtlasResearch. On a server error or a bot check it stops.

Block the bot

Add this to your robots.txt. It blocks everything from Outseen:

User-agent: OutseenBot
Disallow: /
