Source: https://knownagents.com/pricing?subscription_period=yearly ## Key features - **Agent Analytics:** Lists the crawlers, scrapers and AI agents visiting a site in real time, with traffic trends, pages visited, sessions, errors and robots.txt violations per agent. - **AI chat referral tracking:** Counts human visits that come from ChatGPT, Claude, Gemini, Copilot, Perplexity, DeepSeek and other AI chats, kept apart from bot traffic. - **Automatic robots.txt:** Serves a robots.txt that blocks or allows agents by category and updates itself as new bots are found; the WordPress plugin can block bots that ignore it. - **Agent Identification API:** Identifies and verifies the agent behind an incoming request from your own code, for setting access rules by verified identity. - **Server-side collection:** Data is sent from the server, CDN or backend rather than a browser script, so it still works when browser analytics are blocked. - **Agent Directory:** A public directory of thousands of agents and bots that says who runs each one, what it does and how to manage its access. ## Good for - Publishers deciding which AI crawlers to let in or block - Sites that want to measure visits sent by AI chat apps - Developers who need to verify AI agents in their own code ## Worth knowing - It measures bot visits and AI referrals to your site; it does not check what AI engines say about your brand in their answers. - Events include every API call and each item in a batch; the vendor suggests budgeting about twice your monthly human visits. - The free plan stops at its monthly event limit; paid plans get an email suggesting an upgrade when they run over. - It needs a server, CDN or WordPress integration to collect data, rather than a script pasted into the page. ## ToolGPA grades **GPA: 2.6 out of 4**, graded Oct 23, 2026. Known Agents, once called Dark Visitors, shows which AI crawlers and agents hit your site, what they read and whether they ignore robots.txt, and counts the people AI chats send you. The free plan covers 1 project and 100,000 events a month. But it doesn't check what AI answers say about you, every API call counts as an event, the free cap is hard, and it needs a server, CDN or WordPress hookup to collect anything. - **Value for money: B.** Startup is $25 a month billed yearly, or $29 monthly, for 3 projects and 1 million events. That's inside the cheaper quarter of this category, which starts at $29, and well under Siteline's $49. - **Free plan and trial: B.** Free with no card and no time limit: 1 project and 100,000 events a month, which the vendor says covers most websites. It's a hard cap, though, and the premium features are paid. - **Features: C.** Bot and agent analytics, AI chat referrals, a robots.txt that updates itself and an API to verify agents. It does that job fully, but it's a smaller one: it doesn't check what AI engines say about your brand. - **Ease of use: C.** No rating on record. Data comes from your server, CDN or WordPress rather than a pasted script, so there's a bit of plumbing before anything shows up. - **Platforms and integrations: B.** Web only, with no desktop or phone app. It hooks into WordPress, Cloudflare, Fastly, Akamai, AWS, Google Cloud, Vercel and Node.js, and has an agent identification API.
