Seline, sold at seline.com, tracks website traffic, visitor journeys, and revenue attribution without using cookies or triggering a consent banner. It’s positioned as an alternative to Google Analytics, Fathom, and Plausible, aimed at site owners who want the data without the dashboard sprawl.
Seline’s Pro plan runs $14/month, or $9/month if you commit to annual billing, covering 25,000 monthly page views with unlimited websites. A 7-day free trial, no credit card required, is the main way to try it before paying.
What is Seline?
Seline is a young company: founded in July 2024 in Poland, still a 1-10 person bootstrapped team, with founder Kostya Nesterovich saying the product has been in development for a little over two years and now runs on roughly 1,000 websites. It competes directly with Google Analytics, Fathom, and Plausible — the first a free but complex enterprise tool, the other two paid privacy-first alternatives.
The problem Seline targets is the gap between heavyweight analytics platforms that need a cookie-consent banner and a learning curve, and lightweight privacy tools that often stop at pageviews and referrers. Seline adds visitor journeys, conversion funnels, and Stripe-based revenue attribution on top of the basic traffic numbers, plus an AI chat layer, Seline AI, for asking questions about the data in plain English.
Key features
The feature set spans four areas: a real-time overview, visitor-level detail, journey tracking, and revenue attribution.

A real-time dashboard
A single snippet, about 2kb, adds Seline to a site with no complicated setup, and the dashboard immediately starts showing total visits, pageviews, bounce rate, sources, and top pages without a config step.
Visitor-level data and journeys
Referrers, UTMs, countries, devices, and top pages break down in one view, and individual visitor profiles can be enriched with custom properties and Stripe data, with session-by-session journeys showing exactly how someone moved through the site.
Funnels and revenue attribution
Funnels highlight where visitors drop off at each step, and revenue can be attributed to specific channels, UTMs, or referrers through the Stripe integration or custom events, filterable by any custom attribute.
No cookies, no consent banner
Tracking runs without cookies, which the vendor positions as removing the need for a cookie-consent popup, alongside ad-blocker bypass and bot-detection features aimed at keeping the numbers accurate.
Sharing data without extra logins
Dashboards can be shared via secure public links so a client or teammate sees live numbers without needing their own Seline login, and the included public API lets the data feed into other tools rather than staying locked in the dashboard.
Plans and pricing
Seline runs on a single Pro plan priced by monthly page views, with every website on your account sharing one event limit — unlimited websites are included regardless of billing cycle. A Done-for-You setup service is available as an optional one-time add-on for anyone who’d rather not configure tracking themselves.
| Plan | Price | Billing | Key features |
|---|---|---|---|
| Pro (monthly) | $14/month | Monthly | 25,000 page views/month, unlimited websites, forever data retention, revenue analytics |
| Pro (yearly) | $9/month | Annual (2 months free) | Same features as monthly, billed once a year |
| Done-for-You Setup | $99 | One-time add-on | Site integration, custom event configuration, conversion funnel setup, usage guidance |
Who it’s best for — and who should skip it
Seline is best for bloggers, SaaS companies, and small businesses — sites that want to see which channels actually drive revenue without configuring a full Google Analytics property or adding a consent banner. The Stripe-based revenue attribution and MCP support, which one buyer used to connect it directly to Claude, make it a natural fit for teams already comfortable with lightweight, API-friendly tools.
It’s a weaker fit for teams that need deep campaign-level attribution or a built-in UTM builder — a reviewer who tested it noted both are missing — or for high-traffic sites that would quickly outgrow the 25,000-page-view plan and need to budget for usage beyond it.
What users say
Seline carries a 4.5-out-of-5 rating, but from just 2 user reviews at the time of writing, which is too small a sample to call a reliable track record either way — this is closer to an early-access signal than a mature pattern of praise or complaints.
Both available reviews are positive: one buyer with no live traffic yet called the initial setup encouraging and praised being able to configure it through its MCP connection to Claude, and another reviewer called it clean and functional while flagging small issues — a sticky date header overlapping visitor journeys, an AI-generated funnel that added unwanted steps, and Shopify working through a setup guide rather than a native app. Founder Kostya Nesterovich replied personally to both reviews within the day, including resolving a support question about deleting test data in about five minutes.
Price and value
At $9–$14 a month for cookieless analytics with journeys, funnels, and revenue attribution, Seline is priced in line with a comparable Plausible or Fathom subscription, assuming the 25,000-page-view monthly cap fits your traffic.
The value case is strong on paper, but it carries more uncertainty than an established tool with hundreds of reviews: buyers are betting on a two-year-old, 1-10 person company continuing to maintain and improve the product, not just on the feature list at checkout.
Verdict
Seline is a genuinely capable, cookieless analytics tool with useful journey and revenue features at a fair price, but its two-review track record means early buyers are taking more of a chance than usual.
