Which one is for you
Pick Agentrail if
- Fits if you make a developer tool and more of your users now arrive through coding agents
- Works for teams fixing docs, sign-in or an MCP server for agent use
Look elsewhere if
- Skip it if you want to know how AI chat answers mention or rank your brand
- Not for you if you sell to consumers rather than developers
- Tight if you have heavy agent traffic and a fixed budget: it's $0.10 per journey and $1 per simulation
- Too light for more than one product on the free tier, which covers 1 surface and 100 journeys that don't roll over
- Watch out: setup depends on your stack and no integrations are named, so expect engineering time
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
How we grade them
| 2.0GPAAgentrailFair | 2.2GPASitelineFair | |
|---|---|---|
| Value for money | CNo monthly plan: after the free allowance it's $0.10 per agent journey and $1 per simulation, with volume tiers and an optional spend cap. So 1,000 journeys a month comes to about $90 before discounts, in the category's usual range. | CStarter is $49 a month for 500 prompt runs, 2 websites and 500,000 analytics events. That's between the cheaper quarter of this category and its middle. Only monthly prices are shown, with no yearly saving. |
| Free plan and trial | CFree every month with no card: 100 agent journeys, 10 simulations, weekly readiness scans and fixes, on 1 product surface. Any product with real agent traffic will pass 100 journeys, and nothing rolls over. | CA free plan with no card: 1 website and 50,000 agent analytics events a month. That covers the bot traffic side, but prompt tracking, MCP and the API all start on Starter. |
| Features | CJourney stitching across docs, APIs, SDKs and MCPs, failure detection, sandboxed agent runs, readiness scans and fixes with a prompt or pull request. It does that job fully, but it's a smaller one, and it doesn't track AI chat answers. | CAgent analytics, human visits from AI platforms, prompt tracking, citations, ranked fixes and an insights agent. The gap: the pricing table says all major AI platforms without naming them, and the charts show only ChatGPT, AI Mode, Perplexity and Gemini. |
| Ease of use | CNo rating on record. How it connects depends on your stack, and the vendor only says it works from signals in your existing systems, so expect some engineering time. | CNo rating on record. It collects through your host or CDN rather than a browser script, so there's setup on the server side before you see traffic. |
| Platforms and integrations | CWeb only, and no integrations are named in the listing, though it looks at how agents use your own APIs, SDKs and MCP servers. | BWeb only, with no desktop or phone app. It connects through Vercel, Cloudflare, Netlify, Azure CDN, CloudFront, Next.js, WordPress and Fastly, with MCP and a reporting API from Starter. |
| Best for | seeing where coding agents fail on your product | real AI agent traffic plus prompt tracking |

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.
- The differences and the answers to the questions are worked out from those listings.
