google/ksp — Kotlin Symbol Processing API

Description and use

The **google/ksp** project provides the Kotlin Symbol Processing (KSP) API, a lightweight compiler plugin that enables fast, incremental annotation processing for Kotlin code. By offering a high‑performance alternative to kapt, KSP lets developers write custom processors that generate source files, perform validation, or transform code during compilation, making it ideal for building backend tools, libraries, and frameworks.

Problem

google/ksp may be useful when its README and activity match a concrete workflow.

Outcome

Early or unclear: treat as research material until maintenance, releases, docs, and issue activity are verified.

Evidence
