Features & Capabilities

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.

User Reviews

Sehr cooles und praktisches Add-on! Agent View macht es super einfach zu prüfen, wie eine Webseite auf unterschiedliche Crawler bzw. Bots reagiert. Die Darstellung ist übersichtlich und man sieht direkt relevante Unterschiede, HTTP-Status, robots.txt-Einstellungen und weitere Signale. Gerade zum Testen von AI-/Search-Crawlern echt hilfreich. Bin gespannt, wie es sich weiterentwickelt. :)

Is Agent View Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Agent View requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Agent View is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
