VelenPublicWebcrawler — Velen.io crawler
VelenPublicWebcrawler is a web-data crawler associated with Velen.io. Its robots.txt token is VelenPublicWebcrawler. Public documentation is limited, so specifics about its exact purpose and behaviour are marked as not yet verified rather than guessed.
What this means
VelenPublicWebcrawler is a web-data crawler associated with Velen.io. It appears in server logs as an automated fetcher carrying the VelenPublicWebcrawler token.
Public documentation about this crawler is limited. For that reason, this entry describes only the stable identification pattern — the token — and does not assert specifics such as exact crawl purpose, scope, or robots.txt compliance that cannot be confidently sourced. Treat any such specifics you read elsewhere with caution.
How VelenPublicWebcrawler identifies itself
VelenPublicWebcrawler uses the robots.txt user-agent token VelenPublicWebcrawler. Its user-agent string contains that token. Match on the stable token rather than a full version string.
The user agent is a claim and can be copied. Because verification guidance is not clearly published, do not assume IP-range authenticity and do not invent IP ranges. Identify it by the token and treat trust-sensitive decisions conservatively.
- robots.txt token: VelenPublicWebcrawler
- Associated with Velen.io as a data crawler
- Specifics beyond the token: not yet verified in public docs
robots.txt considerations
To disallow VelenPublicWebcrawler site-wide, target its token:
User-agent: VelenPublicWebcrawler Disallow: /
Whether and how strictly it honours robots.txt is not clearly documented, so treat this as a request rather than a guarantee. robots.txt is never an access-control boundary.
How it appears in analytics and logs
A request carrying the VelenPublicWebcrawler token is a Velen.io-associated crawler fetching a URL — a bot event, not a human visit. Because public docs are limited, rely on the token for identification and do not assume specifics that are not documented.
Diagnostic use case
Identify VelenPublicWebcrawler activity in logs by its token and decide robots.txt policy, while treating undocumented specifics with caution.
What WebmasterID can help detect
WebmasterID classifies VelenPublicWebcrawler server-side by its token and surfaces it on the bot-intelligence surface as a data crawler, so you can see its activity per page without parsing logs.
Common mistakes
- Assuming documented behaviour exists where public docs are actually sparse.
- Inventing IP ranges to verify VelenPublicWebcrawler.
- Counting crawler hits as human sessions.
Privacy and accuracy notes
Detection uses only the request user-agent. No human identity is involved. WebmasterID records the crawl as a bot event, separate from human analytics, and never attaches it to a visitor profile.

- Undeclared AI scrapers and how they appear
Some AI scrapers do not declare a recognisable token. They appear with generic user agents, browser-like strings, or forged identities. They cannot be identified by a clean token, so the honest approach is to describe the pattern, verify what you can, and categorise conservatively.
- Verifying AI crawlers
Any client can copy a user-agent string, so a token alone is a claim, not proof. Some vendors, such as OpenAI for GPTBot, publish IP ranges or verification guidance; many do not. Verify before trusting, and never invent IP ranges to fill the gap.
