What is Threads built with?

Threads's iOS app is built with C/C++, Metal (shaders), Objective-C, Swift, and bundles 7 third-party SDKs alongside Apple's own frameworks. This page lists the languages, frameworks, SDKs, and capabilities detected in the App Store build.

Which third-party SDKs does Threads use?

We detected 7 third-party SDKs in Threads, grouped by purpose — analytics, crash reporting, payments, networking, and more.

How was Threads's tech stack determined?

By statically inspecting Threads's iOS App Store build — linked libraries, embedded frameworks, Swift package modules, privacy manifests, and entitlements. Nothing is executed and no private data is accessed.

Method

How this is detected

Detected SDKs are a lower bound — Threads may bundle more than static analysis can attribute.
The App Store binary is encrypted with Apple FairPlay, so detection is limited to what is observable without decryption.
