Which one is for you
Pick Doppler if
- Fits if you want to see answers as different kinds of buyer would get them
- Works for Nuxt sites that want AI crawler and click data
Look elsewhere if
- Too light for real tracking, with 5 prompts on Starter and 15 on Growth
- Skip it if you need Gemini, Claude or Google AI Overviews, which aren't tracked
- Not for you if you can't add code to your site, as the analytics need the SDK
- Tight if you're on Starter: 1 persona, 1 domain and 1 seat
- Watch out: only yearly prices are shown, and the homepage names Google AI Mode, which no plan tracks
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
| 2.0GPADopplerFair | 2.2GPASitelineFair | |
|---|---|---|
| Value for money | C$33 a month billed yearly sits just above this category's cheaper quarter ($29 or less), and it buys 5 prompts on two engines for 1 domain. Growth is $108 for 15. The monthly-billed prices aren't shown. | 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 | CNo free plan, but a 7-day free trial with no credit card required. | 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 | CPersonas and locations, chat replay, competitor and source checks, plus AI clicks and crawler dates from its SDK. The gaps: only ChatGPT and Perplexity on every plan, and tiny prompt limits. | 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. Prompt tracking works from the dashboard, but the analytics half needs its SDK in your site's code, ready-made only for Nuxt. | 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. Nuxt is the one ready-made integration; anything else means setting up the SDK by hand. | 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. |

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.
