Seline Review: A Privacy-First Google Analytics Alternative Worth Watching (2026)

Seline Review: A Privacy-First Google Analytics Alternative Worth Watching (2026) — illustration

Last updated: July 21, 2026.

Most teams don’t leave Google Analytics because they found something dramatically better. They leave because GA4 got confusing, the cookie banner got embarrassing, and legal started asking questions about where the data lives. That’s the gap a whole category of privacy-first analytics tools grew into, and Seline is one of the newer names in it.

I spent time with it to see whether it’s a real option or just another Plausible clone with a different logo. Short version: it’s genuinely its own thing, with one caveat worth knowing before you get attached.

What Seline actually is

Seline is a cloud-hosted, cookieless web and product analytics platform. It came out of a small bootstrapped team in Warsaw in 2024, and the whole pitch is built around two ideas: keep the tracking script tiny, and keep the data private and in the EU.

The script is about 2kb. For comparison, Google’s tag is heavy enough that people build whole performance budgets around deferring it. Seline’s claim is roughly 23x lighter, and while I wouldn’t treat any vendor’s own number as gospel, the practical effect is real: you add one HTML snippet and you’re not paying for it in Lighthouse points. Setup is a copy-paste, with documented paths for Next.js, WordPress, Webflow, Framer, Shopify, Ghost, and Carrd.

Privacy is the other half. There are no cookies. Instead of storing an identifier on the visitor’s device, Seline uses non-reversible hashing off signals like IP, browser, and device to recognize sessions. Nothing lives client-side, which is why sites using it generally skip the consent banner. Data sits on servers in Germany, the company is EU-based, and they’re explicit that they don’t sell or share it. If your reason for leaving GA was a compliance conversation, this is the part that matters.

It goes further than “pretty pageview charts”

This is where Seline separates itself from the minimalist crowd. Plausible and Fathom are deliberately simple: traffic, sources, top pages, done. Seline covers that baseline (page views, referrers, countries, devices, UTMs) but then keeps going into territory that’s usually a separate product.

You get custom events for the things that actually matter, like button clicks, form submissions, and signups. You get conversion funnels to see where people drop. You get individual visitor journeys, so you can follow a single session through the site instead of only reading aggregates. There are user profiles with custom attributes, which starts to look more like a lightweight product-analytics tool than a website counter.

The one that caught my attention is revenue tracking. Seline integrates with Stripe, Polar, and Shopify, so you can tie traffic and events to actual money. For a small SaaS or store, being able to answer “which source brought revenue, not just clicks” inside your analytics tool, without wiring up a separate pipeline, is a genuinely useful thing to have.

The AI features, with the hype dialed down

Seline leans into AI, and I’ll give it a fair but skeptical read. There’s an AI chat assistant that lets you ask questions of your data in plain language and have it generate CSVs, and there’s an MCP interface, which means you can point an AI agent at your analytics directly. It also flags referrers from AI tools like ChatGPT, Perplexity, and Claude, which is quietly one of the more forward-looking touches given how much discovery is shifting toward AI answers.

Is any of this going to replace an analyst? No. But “ask a question, get a chart or a CSV” removes a real friction point for founders who know what they want to know but not which dashboard to click. Treat it as a convenience layer, not magic, and it holds up.

Rounding out the list: a live globe view of current visitors, bot detection, and filtering by custom attributes, UTMs, dates, and engagement. The globe is eye candy. The filtering is the part you’ll use daily.

The catch: there’s no free plan

Now the part you need to know before you get attached. Seline has no free tier. It’s a single Pro plan, billed monthly or annually, with annual giving you two months free, and it’s scoped around 100,000 page views a month. The team is candid about why: they’re bootstrapped and run entirely on subscriber fees, not on a free plan subsidized by selling data. I actually respect the honesty of that positioning, and it’s consistent with the privacy story. But it does mean Seline isn’t the tool for a hobby project or a portfolio site where you just want a free counter.

I’m not going to quote a dollar figure here because these things change and the price loads dynamically on their site. Check the pricing page for the current number before you budget anything off this post. What matters structurally is the model: one plan, no artificially locked features, pay to play.

Who it’s for, and who it isn’t

Seline fits you well if you’re a small-to-mid SaaS, an indie product, or a store that wants privacy-first analytics but has outgrown “just pageviews.” The revenue tracking and event funnels are the draw, and the EU hosting closes the compliance question. If you’ve been running Plausible and keep wishing it did just a bit more on the product side, this is the natural step up.

It’s a weaker fit if you need a free tool, if you specifically want self-hosting (Seline is cloud-only, so an open-source option like Umami serves that better), or if your analytics depend on Google’s ad-network integrations. Those are real constraints, not dealbreakers for most people, but know them going in.

Bottom line

Seline is a well-scoped, privacy-first analytics tool that does more than the minimalist crowd without turning into an enterprise monster. The 2kb script and EU hosting handle the two reasons people leave GA4, and the revenue tracking plus AI querying give it a reason to exist beyond “Plausible but different.” The no-free-plan decision is the one thing that will filter people out, and it should: this is a paid tool for teams that treat analytics as worth paying for.

If that’s you, it’s worth a look. Start with your highest-traffic site, wire up one revenue integration, and see if the “money, not just clicks” view changes how you read your traffic. That’s the test that tells you whether Seline earns its keep.

Frequently Asked Questions

Is Seline a good Google Analytics alternative?

For privacy-conscious teams, yes. Seline is cookieless, EU-hosted, and ships a roughly 2kb script instead of GA4's heavier tag. It covers page views, custom events, funnels, and revenue tracking, so most teams that left GA4 for compliance or simplicity reasons will find their core needs met. It's a weaker fit if you rely on deep audience-network integrations that only Google provides.

Does Seline use cookies?

No. Seline identifies visitors with non-reversible hashing based on signals like IP, browser, and device rather than storing a cookie on the visitor's device. Because nothing is stored client-side, sites using it generally don't need a cookie-consent banner. Confirm your own compliance obligations, but that's the design intent.

Does Seline have a free plan?

No. Seline is a bootstrapped product with a single paid Pro plan, billed monthly or yearly (annual billing includes two months free). There's no permanent free tier. If you need free analytics, an open-source self-hosted option like Umami is a better fit; Seline is aimed at teams willing to pay for a managed, privacy-first tool.

Where is Seline's data hosted?

In the EU, on servers in Germany, over HTTPS. The company describes itself as legally based and hosted in the EU and says it doesn't sell or share data with third parties, which is the main reason GDPR-sensitive teams look at it.

How does Seline compare to Plausible?

They share the privacy-first, lightweight-script DNA, but Seline reaches further into product analytics: revenue tracking (Stripe, Polar, Shopify), individual visitor journeys, user profiles, and an AI query interface. Plausible is more minimal and open-source with self-hosting. Seline is cloud-only and does more out of the box.
