About these scores

OSS scale score is an unbounded metric that log-compresses and weights Stars, Watchers, Forks, and Contributors. Discovery score is the current OSS scale score minus the score at discovery. Update pace is commits in the last 30 days, growth momentum is the OSS scale score difference within the recent observation window, and OSS health is a 0–100 rating based on available recency, Community Health, and release data.

Overview

Coil is a Kotlin-first image-loading library for Android and Compose Multiplatform. It integrates memory and disk caching, downsampling, and automatic request pausing or cancellation, while Compose applications can render images through AsyncImage. Network fetching is selected through separate OkHttp or Ktor modules.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Key features

Load images in Compose through AsyncImage

Adding coil-compose provides the AsyncImage composable for binding an image model directly into Compose UI while Coil manages request execution.

Sources: [1]

Use memory and disk caching with downsampling and lifecycle-aware requests

The README highlights memory and disk caching, downsampling, and automatic pausing or cancellation as core optimizations for image-heavy screens.

Sources: [1]

Choose a networking module such as OkHttp or Ktor

Coil 3 separates networking from the Compose artifact. The Quick Start pairs coil-compose with coil-network-okhttp, allowing applications to select a network stack.

Sources: [1]

Best fit

Fits shared image loading across Android and Compose Multiplatform

It suits Kotlin and Compose applications that want fetching, decoding, caching, and presentation to follow a common API across supported platforms.

Sources: [1]

Before adoption

Add a networking dependency explicitly for HTTP images

coil-compose alone does not provide an HTTP network implementation. Add an OkHttp or Ktor networking artifact according to the application's stack.

Sources: [1]

Android projects need minSdk 23 or newer

The 3.6.3 Gradle configuration sets Android minSdk 23 and compile/target SDK 37, so existing applications should verify their minimum OS policy.

Sources: [2]

Pin 3.6.3 and verify compatibility with build tooling

Released September 18, 2026, version 3.6.3 fixes an Android Gradle Plugin 9.4.0 and R8 build failure. Regression-test build compatibility when upgrading Kotlin, Compose, AGP, or Coil.

Supplemental curator note

Coil fits Compose applications that want image loading to follow UI lifecycle with selectable networking integrations. Validate placeholders and caching together with request cancellation, image sizing, and network behavior on representative devices.

Try it in 3 steps

  1. 1

    Add Coil 3.6.3 Compose and networking modules

    Add the Compose artifact and the OkHttp networking artifact at the same pinned version.

    implementation("io.coil-kt.coil3:coil-compose:3.6.3") implementation("io.coil-kt.coil3:coil-network-okhttp:3.6.3")
  2. 2

    Render an image with AsyncImage

    Pass a URL as the model and let Coil handle fetching, decoding, caching, and request lifecycle integration.

    AsyncImage(model = "https://example.com/image.jpg", contentDescription = null)
  3. 3

    Verify the Android build

    Confirm that 3.6.3 builds with the application's minSdk, Compose, AGP, and R8 configuration.

    ./gradlew assembleDebug
