Can I migrate from Aptabase to Crxlytics easily?

Yes — migration takes about 15 minutes. Both SDKs expose a similar track(event, props) API, so most call sites change one import. You can also run both SDKs in parallel for a few weeks during the switchover. Auto-events like install/update/uninstall are wired automatically by Crxlytics — no manual setup needed.

Does Crxlytics support multi-platform like Aptabase?

No. Crxlytics only supports Chrome extensions (and other Manifest V3 WebExtensions like Edge and Firefox). If you also ship iOS, Android or desktop apps, Aptabase is the better choice for a unified SDK. We made a deliberate trade-off: depth over breadth.

Is Crxlytics open source like Aptabase?

Not yet. Aptabase is fully open source (Apache 2.0) and self-hostable. Crxlytics is closed source for now, though our event-ingestion API can be deployed standalone to your own Railway, Fly.io, or Docker host. The hosted dashboard is managed by us.

What does Crxlytics offer that Aptabase doesn't?

Automatic install/update/uninstall tracking via chrome.runtime hooks, chrome.alarms-based event flushing that survives service-worker termination, a pre-init event buffer so async init can't drop events, automatic churn pattern classification (single-session, error-driven, never-activated, site-trigger), Chrome Web Store attribution tracking, and planned features like uninstall reason surveys, service-worker health metrics, and CWS rating monitoring.

How much does Crxlytics cost compared to Aptabase?

Crxlytics has a free Hobby tier (10,000 MAU, 30-day retention) and a Team tier at $49/month (100,000 MAU, 12-month retention, churn detection, alerts). Aptabase pricing is similar at the lower end and self-hosting is free. Founder pricing is locked in for waitlist signups.

aptabase alternative

The Chrome-native alternative
to Aptabase.

Aptabase is great for multi-platform analytics. But if you only ship Chrome extensions, Crxlytics gives you MV3 lifecycle tracking, churn detection and uninstall surveys — built specifically for chrome-extension:// origins.

Let's be upfront: Aptabase is a solid tool. Open source, privacy-respecting, fair pricing, supports Web, iOS, Android, Desktop and Chrome extensions from one SDK. If you need cross-platform analytics, it's a legitimately good choice.

Crxlytics is different on one axis: we only do Chrome extensions, and we go deep. Manifest V3 service-worker hardening, automatic install/update/uninstall tracking, churn pattern detection, attribution from the Chrome Web Store, uninstall surveys. Things you'd otherwise build yourself on top of any generic analytics SDK.

// why developers switch

What you get out of the box that you’d otherwise build.

You stopped fighting MV3 bugs.

Service workers suspend after 30s of inactivity. Most analytics SDKs lose events when that happens. Crxlytics uses chrome.alarms to wake the worker on schedule, flushes on onSuspend, and buffers events that fire before init completes — so install/uninstall events never get silently dropped.

You see why users leave.

Aptabase tells you the event count. Crxlytics correlates uninstalls back to last-seen patterns — was it the error 3 days ago, the never-activated cohort, the site-specific trigger? The churn engine surfaces patterns automatically.

You don’t build your own funnels.

Chrome Web Store attribution, install → activated → retained cohorts, feature usage heatmaps — wired by default. With a generic SDK you’d build all of this on top in SQL or a custom dashboard.

// when aptabase is the better fit

We won’t pretend.

If any of these apply, Aptabase is probably the better choice for you:

·You ship beyond Chrome. Mobile apps, desktop, web — Aptabase has one SDK for all of them. Crxlytics only does Chrome extensions.
·You need open source. Aptabase is Apache 2.0 — self-host the entire stack yourself. Crxlytics is closed source for now, though our API can be deployed standalone.
·You need it today. Aptabase is battle-tested in production. Crxlytics is in early access — we’re shipping fast, but if you need years of track record right now, take the safer bet.

Migration takes ~15 minutes.

You can run both SDKs in parallel for a few weeks if you want. Both expose a similartrack(event, props) API — most call sites change one import and you’re done. Auto-events (install/update/uninstall) are wired for you automatically.

Common questions, honestly answered.

Aptabase is a multi-platform analytics tool (Web, iOS, Android, Desktop, Chrome extensions) with a single generic SDK. Crxlytics only does Chrome extensions but goes deeper: MV3 service-worker hardening, automatic install/update/uninstall tracking, churn pattern detection, Chrome Web Store attribution, and uninstall surveys — features you’d otherwise build on top of a generic analytics SDK.
