Three tools.One instrument.

The common shape has three vendors in it. Google Analytics for traffic: free, built around the ads ecosystem, with product questions answered through hand-built Explorations. Hotjar for replay and heatmaps: a subscription tiered by how many sessions you record. And a performance product for Core Web Vitals: typically priced per site or by data volume. Three scripts on the page, three dashboards, three companies holding your visitors’ data.

The costs that do not appear on the invoices: every tool counts a session differently, so the numbers disagree on principle; every added script is another consent conversation; and the metered tools need watching, because the bill moves when your traffic does.

The bill becomes one flat number: $29, $79 or $199 a month, sized by traffic, with every feature on every plan. Whether that beats what you pay today depends on your stack and your volumes, and that arithmetic is yours to run; what the flat price removes for certain is the metering.

The data becomes one model. The visitor who dropped out of the funnel, the session you replay to see why, and the page whose LCP regressed are the same records in the same Postgres, so the tools cannot disagree about what a session is. There is one tab bar over all of it.

The page gets lighter and the list of parties shorter: one first-party tag of 1.0 KB gzipped, plus a 1.9 KB extras file when you switch capture on, all served from your own instance. One vendor to assess instead of three, and the vendor’s infrastructure is a machine rented for you alone.

Real things. GA4’s Google Ads integration has no counterpart here: if analytics exists to feed bidding, keep GA4. Hotjar’s surveys and feedback widgets are absent: juuna watches behaviour, it does not ask questions. Dedicated performance suites go deeper than field vitals, with tracing and lab runs juuna does not attempt. And a free stack can be assembled from GA4 and Microsoft Clarity, at the price of living on those vendors’ infrastructure and terms.

So the pitch is not that juuna does everything the stack does. It is that the part most product teams actually use, traffic, funnels, retention, replay, heatmaps and vitals, fits in one tool, on one server, at one price that stays put.
