Wire AI vs Firebase A/B Testing for mobile activation
Both run live experiments in a shipped mobile app without a release. The difference is who does the work. Firebase A/B Testing sits on Remote Config, and Google's own documentation is explicit that you define the variants you want to evaluate. That is the part a solo founder never gets to. Wire AI writes the variants for the onboarding, the value moment, the walkthrough and the review ask, runs four at once, reads which one keeps people, and holds the winner. You set the goal. If you already have a growth person writing variants every week, Firebase is free and you should use it.
Every claim about Firebase A/B Testing on this page links to Firebase A/B Testing's own public documentation or pricing page, with the date it was read. If a source moves, the claim comes down.
Side by side
| Feature | Wire AI | Firebase A/B Testing |
|---|---|---|
| Who writes the variants | The AI writes them, you approve and can freeze a winner | You do. The docs say you define the variants you want to evaluate[1] |
| What the experiment runs on | Native React Native components rendered by the open-source Wire RN SDK | Remote Config parameter values, with Google Analytics for the goal metric[1] |
| Concurrent experiments | Per surface, no project-wide cap | Up to 24 running experiments per project at a time[2] |
| Metrics tracked per experiment | The activation funnel, drop by step, plus per-arm outcomes | One goal metric plus up to five additional metrics[2] |
| Config surface limits | Not applicable, the flow is generated per user | 3,000 parameters per template type, 2,000 conditions per project[3] |
| Price | MAU tiers from €49 a month. Analytics free to 1M events a month | A/B Testing is part of the Firebase console |
| React Native fit | React Native and Expo first, one package, one key | Firebase SDKs plus a community React Native layer |
Where Firebase A/B Testing wins
It is already in your app. If Firebase Analytics is installed, A/B Testing is a console tab away, and Google's docs describe it as working with Remote Config so you can test changes inside the app and with Cloud Messaging so you can test marketing messages.[1]
The targeting is genuinely deep. App version, build number, language, country, user audience, user property, first-open timing, and any percentage between 0 and 100. If your experiment is really a segmentation question, Firebase answers it better.[2]
Remote Config is a real config layer, not just an experiment tool. 3,000 parameters per template type buys you a lot of runtime switches that have nothing to do with activation, and you probably want that regardless of what else you run.[3]
Where Wire AI wins
The variant writing is the job. A Remote Config experiment is a container, and it is empty until somebody sits down and writes version B. Wire fills the container. That is the entire product, and it is why the comparison is not really about features.
Wire ships the surfaces, not just the switch. Onboarding, the value moment, the walkthrough at the point of need, and the review ask all render as native components from one package, so there is no gap between what the experiment says and what the user sees.
It answers Apple guideline 2.5.2 the boring way. The open-source kit renders server-driven UI from JSON into React Native components you shipped in your own binary. No WebView, no downloaded code.
One package and one key covers the flow, the funnel events, the experiment assignment, and the review gate. @wireai/activation is at 0.11.0 on npm, wireai-rn at 0.2.4, both MIT for the renderer.
What Wire AI does not do
- Wire is younger than Firebase by roughly a decade, and there is no third-party ecosystem of Stack Overflow answers behind it yet.
- There is no general-purpose remote config layer. If you want a runtime switch for something that is not part of the user journey, that is not what this is.
- iOS and Android through React Native. No web target, no native-only SDK.
- The receipt today is onboarding completion, currently 92% in a live consumer app I run engineering for, and a founding cohort of 15 seats with 3 filled. That is honest and it is early.
How to pick
Use Firebase A/B Testing if
somebody on your team writes the variants already, you need segment-level targeting, or your experiment is about a config value rather than a screen.
Use Wire AI if
you are the whole team, the experiments never get written because writing them is a week of work, and the thing you want to move is the first session.
Run both if
you keep Remote Config for runtime switches and let Wire own the journey surfaces. They do not fight; one is a config layer, the other writes and runs the experiences.
Questions people actually ask
Is Firebase A/B Testing free?
A/B Testing is available in the Firebase console alongside Remote Config, and Google publishes the quotas for both. The cost that actually bites is not the bill, it is the person-hours to design each experiment and read each result.
Can I keep Firebase Analytics and still use Wire AI?
Yes. The kit emits typed events you can forward to whatever analytics you already run, with canonical names so the same funnel reads identically across apps.
How many experiments can Firebase run at once?
Google documents up to 24 running experiments per project at a time, and lists experiments and rollouts as 24 combined in the Remote Config quotas.
Does Wire AI need Firebase?
No. They are independent. Plenty of apps run both because Remote Config is useful for things that have nothing to do with activation.
