How is the tech stack detected?

We statically analyze the iOS App Store build of each app - inspecting linked libraries, embedded frameworks, Swift package modules, privacy manifests, and entitlements - to identify languages, Apple frameworks, and third-party SDKs. No code is run and no private APIs are used.

Which third-party SDKs are detected?

We surface the third-party SDKs found in the current iOS App Store build, grouped by purpose - analytics, crash reporting, ads, payments, networking, and more - from linked frameworks and Swift package modules.

Why is only iOS covered?

Tech stack extraction currently runs against iOS App Store builds. Android coverage isn't available yet, so the tech stack pages and per-app tabs only appear for iOS apps we've analyzed.

How often is it refreshed?

Tech stack data is regenerated when we re-analyze an app's latest build. Each app page notes the analyzed version, and flags when that build lags the current App Store release.
