Can AI replace AppsFlyer?
You can absolutely build a click tracker: log clicks, generate deep links, receive install pings from your own SDK, join them in SQLite. What you cannot build is the reason AppsFlyer exists, which is that Meta, Google, TikTok and Apple do not hand raw attribution data to random self-hosted endpoints. Those self-attributing networks report only to certified measurement partners, and SKAdNetwork/AdAttributionKit postbacks are aggregated and privacy-thresholded by design. Add install fraud detection, which is a data problem across billions of devices rather than a code problem, and the gap stops being about engineering effort. The honest consolation build is a first-party attribution tracker for channels you control: your own links, emails, influencer codes, organic web to app.

02Could AI build it for you?
The core job: A self-hosted link tracker that issues tagged deep links, logs clicks, and matches them to install and event pings from your own app SDK to give you first-party attribution for channels you control.
What a working version needs:
- A server with a public HTTPS domain for click and postback endpoints
- Ability to add a small SDK or HTTP call to your own iOS/Android app
- Apple App Site Association and Android assetlinks.json files served for deep linking
- Your own ad account exports if you want spend numbers next to installs
The click logger is a weekend, the attribution is not. The moat is certified access to networks that refuse to report to anyone else, plus fraud signals drawn from device data across the whole industry.
03What you'd give up
- Self-attributing network data from Meta, Google, TikTok and Apple Search Ads, which is restricted to certified measurement partners
- SKAdNetwork and AdAttributionKit postback handling, decoding and conversion value modeling
- Install and click fraud detection, which depends on cross-advertiser device data you will never have
- Postbacks and audience syncs to thousands of ad partners and MMP-only integrations
- A maintained SDK that survives every OS release, ATT prompt change and privacy policy update
- Deterministic cross-device and cross-platform identity resolution
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.
