A fast, lightweight, and modern Kotlin-first image loading library for Android and Compose Multiplatform.
Coil is an image loading library for Android and Compose Multiplatform applications. It handles fetching, caching, and displaying images efficiently with a focus on performance and minimal boilerplate. The library solves the common challenge of managing image resources in modern mobile and cross-platform development.
Android and Compose Multiplatform developers who need a reliable, Kotlin-first solution for loading images in their apps. It's particularly suited for projects using modern Kotlin libraries like Coroutines and Jetpack Compose.
Developers choose Coil for its lightweight design, fast performance optimizations, and seamless integration with modern Kotlin ecosystems. Its Kotlin-first API reduces boilerplate and aligns well with contemporary Android and multiplatform development practices.
Image loading for Android and Compose Multiplatform.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Implements memory and disk caching, image downsampling, and automatic request pausing/cancelling to ensure fast and efficient image loading with minimal app overhead.
Depends only on Kotlin, Coroutines, and Okio, which reduces library bloat and integrates seamlessly with R8 code shrinking for smaller app sizes.
Leverages Kotlin features like coroutines and extension functions to minimize boilerplate, making image loading code concise and idiomatic for modern Kotlin development.
Designed to work natively with Jetpack Compose, Compose Multiplatform, OkHttp, and Ktor, providing seamless integration in contemporary Android and cross-platform apps.
Requires projects to adopt Kotlin and Coroutines, posing a barrier for Java-centric teams or those unfamiliar with asynchronous Kotlin programming.
Focused solely on Android and Compose Multiplatform, excluding other platforms like iOS with SwiftUI or desktop applications without Compose, restricting broader cross-platform use.
As a modern library, major version updates (e.g., Coil 2 to Coil 3) can introduce breaking changes, necessitating migration efforts and potential code adjustments.
