Nexly vs Umami

Umami is an open source privacy analytics platform with funnels, journeys, retention, session replay, and performance monitoring. Nexly trades some of that breadth for built-in AI analysis, proactive anomaly detection, and native app SDKs.

Choose Nexly if

  • You want Insights and anomaly alerts explaining the numbers, not just showing them
  • You want 24 months of raw events instead of 6 months on the free tier
  • You track apps too: React Native, Flutter, native iOS, Kotlin Android, and Node SDKs are included
  • You want unlimited websites and team members on every plan — Umami's free tier covers one website

Choose Umami if

  • You want an open source tool you can self host for free
  • You need a bigger free event allowance and 6 months of history is enough
  • You want open source analytics with session replay and performance monitoring

Showing versus explaining

Umami has grown well past a pageview counter: funnels, user journeys, retention, goals, and Core Web Vitals monitoring are all there, with session replay and heatmaps on the Business tier. What it does not do is explain. Nexly puts the analysis layer on top of the same cookieless basics: anomaly detection flags unusual days and opens them in Insights with one click, and Insights answers why a metric moved, with charts and links to the exact view.

History that outlives the free tier

Umami's free cloud plan keeps 6 months of data, which is exactly when year-over-year questions start. Nexly keeps raw events for 24 months and aggregated statistics for up to 5 years on every plan, including the free 10,000-event tier.

Traffic that is not human

Most tools silently filter bot traffic out. Nexly classifies every event it receives instead — search engine crawlers, AI bots, link previews, datacenter traffic — and shows them in a dedicated section, kept out of your human metrics. It also tracks AI referrals: real visitors who arrive from ChatGPT, Perplexity, and other assistants. One honest caveat applies to every script-based tool, Nexly included: crawlers that never execute JavaScript stay invisible.

Switching from Umami

  1. Create a free Nexly property and swap the Umami script for the Nexly snippet.
  2. Recreate your Umami events as Nexly custom events with typed properties.
  3. Export your Umami data for your records, then remove the old script when the overlap period ends.

Common questions

Umami's free tier allows more events. Why pick Nexly?
If raw event volume is the only criterion, Umami's free tier is generous. Nexly's free plan trades volume for depth: unlimited websites, unlimited team members, funnels, AI insights, anomaly alerts, and 24 months of raw event history.
Is Nexly open source or self hostable?
No. Nexly is a managed service. If self hosting is a hard requirement, Umami's MIT licensed version is a great fit. In exchange, Nexly ships funnels, AI insights, and mobile SDKs that you do not have to operate yourself.
Can I import my Umami data?
There is no direct import. Run both tools in parallel during the switch so your trend history stays continuous.
How do Nexly events compare to pageviews?
Nexly bills monthly events: each pageview and each custom product event counts once. Session housekeeping signals do not. Many privacy analytics tools label pricing tiers in pageviews — some bill pageviews only, others also count custom events under that label. Treat same-number volume comparisons as approximate. If you only know your pageview count, add the product events you plan to send (signups, checkouts, feature use) before picking a Nexly tier. A site that looks cheap at pageview-only volume can land on a higher plan once product analytics is in earnest.
Does Nexly use cookies?
No. Nexly never uses cookies. By default identifiers live in local storage, and privacy mode removes device storage entirely with a daily rotating pseudonymous fingerprint.
