image-demo.mp4
A performant way to render images in React Native with a focus on speed and memory usage. Powered by Nuke, the smallest and most performant image loading library for iOS and macOS and Coil on Android.
The framework is lean and compiles in under 2 seconds¹. Nuke has an automated test suite 2x the size of the codebase itself, ensuring excellent reliability. Every feature is carefully designed and optimized for performance.
Coil performs a number of optimizations including memory and disk caching, downsampling the image in memory, automatically pausing/cancelling requests, and more.
- Supports visionOS
- Fast image loading
- Memory and disk caching
- Placeholder support:
- Animated transition
- Failure image
- Typescript support
- Written in Swift/Kotlin
- GIF support
