- Works for developers who need to verify AI agents in their own code through an API
Look elsewhere if
- Skip it if you want to know what ChatGPT says about your brand, as it doesn't check answers

- Watch out: the free plan stops at 100,000 events a month, with 1 project and only the basic features

Pick Siteline if
- Fits if you want measured AI agent traffic from your server, not only simulated prompts
- Works for developer tools that want to see which coding agents read their docs
Look elsewhere if
- Skip it if you need to know which AI engines are tracked before you pay, as the table doesn't name them
- Not for you if you can't change your hosting or CDN setup, since it collects on the server side
- Tight if you stay free: prompt tracking, MCP and the API all start on Starter at $49 a month
- Watch out: prices are monthly only, with no yearly saving and no stated trial on paid plans
- Tight if you want Slack support, which starts on Scale at $99 a month

Key features
Known Agents

- 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.
Siteline

- Counts the human visits that arrive from OpenAI, Claude, Gemini, Perplexity, Meta AI and other AI platforms, next to the agent visits.
- Visibility tracking
- Suggests the prompts that matter in your category, then tracks your visibility, ranking and positioning against competitors in AI answers.
- Citation monitoring

- Server-side integrations
- Connects through Vercel, Cloudflare, Netlify, Azure CDN, AWS CloudFront, Next.js, WordPress or Fastly rather than a browser script.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
