A Firebase Analytics alternative with the answers already built.
Firebase Analytics is free and covers every platform. Union is narrower on purpose: one iOS app, one panel that already answers who is in the app, whether a feature works, whether a release helped and what goes with subscriptions.
Union and Firebase Analytics, side by side.
| Union | Firebase Analytics | |
|---|---|---|
| Price | 100,000 events a month | No cost; project-level quotas apply |
| Live view | Yes: Who is in the app now, per person, within seconds | Partly: Realtime report of the last 30 minutes, best effort, minutes of delay |
| Crash reporting | Yes: Built in, grouped into issues, named with dSYMs | Yes: Crashlytics, a separate Firebase product, with dSYMs |
| Subscription revenue | Yes: RevenueCat or App Store Server Notifications | Partly: Through RevenueCat’s Firebase integration |
| Platforms | Partly: iOS, plus server-side events | Yes: Apple, Android, Flutter and Unity (Crashlytics) |

Why teams pick Union over Firebase Analytics.
Answers, not a report builder
Live, sessions, features, releases, crashes and revenue are views that exist on day one, each number with its definition.
Live means now
A person-by-person view of who is in the app this minute, not a count of the last half hour.
One place for the release
Adoption, crash-free rate and the before/after of a version on one page, instead of Analytics, Crashlytics and App Store Connect side by side.
When Firebase Analytics is the better choice.
- You ship on Android, Flutter or Unity as well as iOS.
- You need it to cost nothing at any scale.
- You already live in Google’s tools (BigQuery, Google Ads).
Questions about switching from Firebase Analytics.
Can I run Union next to Firebase?
Yes. The Union SDK is independent; many apps keep Crashlytics or Analytics while trying Union.
Is Union free like Firebase?
Up to 100,000 events a month, yes. Above that plans start at €9 a month for 1 million events.
