Apollo Kotlin is a strongly-typed, caching GraphQL client for the JVM, Android, and Kotlin multiplatform.
The tool solves the problem of safely consuming GraphQL APIs from Kotlin applications by generating type-safe code from your GraphQL schema and queries. It provides intelligent caching with both in-memory and SQLite options out of the box, eliminating the need to manually manage network requests and data synchronization. The approach combines code generation for compile-time type safety with a powerful caching layer that handles complex query patterns automatically.
Teams building Android apps or Kotlin multiplatform projects should consider Apollo Kotlin if they want to eliminate entire categories of runtime errors related to API integration. It suits projects that prioritize type safety and developer experience, particularly those already invested in the Kotlin ecosystem. The tool includes an IntelliJ plugin for enhanced development experience and supports modern GraphQL features like persisted queries and the @defer directive for optimized network usage.
The project maintains a substantial base of real-world adopters who report issues and drive the development agenda. Maintainers respond to new issues and pull requests within a day. Work in the issue tracker centers on bug fixes, feature requests, and user questions, reflecting active engagement with both problems and enhancement opportunities.
