Can I open-source AppsFlyer?
NOT REALLY · nothing credible yetNo credible open-source replacement for AppsFlyer yet — Plausible and Umami are the closest escape hatches, but they don't cross the moat. Because attribution is not a computation, it is an entitlement. The moment a meaningful slice of your spend goes to Meta or Google or TikTok, your homegrown tracker sees a blob of untagged traffic and shrugs, while the ad networks themselves only talk to partners they have certified. On top of that, media buyers want a neutral scorekeeper both sides accept, finance wants one number, and nobody wants to argue with a partner about whose SQL is right. The price is the referee, not the dashboard.

How much does AppsFlyer cost?
AppsFlyer's pricing is usage-based or varies by plan · No flat monthly price: Growth is $0.07 per conversion after the included welcome package; Enterprise is contact-sales..
