Agent View tekijä Tihomir Thomas Bicanic

Agent View is a Firefox extension for inspecting how websites respond to different client identities.
It can request the same URL as a normal browser, ClaudeBot, GPTBot, OAI SearchBot, PerplexityBot, Googlebot or with Accept: text/markdown.
Responses are shown in one workspace where status, content type, size, detected markers, normalized text, headers and raw content can be inspected.
When several profiles are selected, Agent View compares their responses and highlights meaningful differences.
Agent View also checks website signals including robots.txt, crawler access for the current URL, Meta Robots, X Robots Tag, canonical URLs, sitemaps, JSON LD, llms.txt and Markdown links.
Requests are made without cookies. JavaScript from the target website is not executed.
Agent View does not use an external AI service and does not send telemetry or analytics to the project author.
Changing a User Agent does not make a request equivalent to traffic from the real crawler infrastructure. Websites may use IP verification or additional checks.
