Coursier review
A focused open-source choice for JVM and Scala artifacts, with caching and offline use.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Coursier is an open-source Scala application and artifact manager for resolving and downloading JVM, Scala, and related platform dependencies. It is aimed at developers who need command-line artifact fetching, dependency resolution, Scala application installation, or development-environment configuration. Coursier supports Linux, macOS, and Windows, and also provides a Scala API for dependency resolution and artifact fetching.
Its strongest fit is dependency management across Maven and Ivy repositories. Coursier reconciles transitive dependencies, supports custom repository configuration and mirrors, and handles private repository authentication through credentials and credential files. Local artifact caching supports offline operation for dependencies already available in the cache. The tool can also install JVM-based applications and Scala tools, giving teams a single utility for both retrieving artifacts and managing selected JVM applications.
Coursier is a focused choice rather than a broad package-management system. Its package formats are Maven and Ivy, and its model is a local developer tool rather than a hosted subscription service. That makes it suitable for JVM and Scala workflows where repository configuration, dependency reconciliation, caching, and offline access matter. Teams seeking those capabilities should find its scope aligned with their environment; teams needing package formats beyond Maven and Ivy or a hosted service should consider a different product.
Coursier pros and cons
- Where it wins
- Reconciles transitive dependencies across Maven and Ivy repositories
- Supports mirrors, custom repositories, and private credentials
- Caches artifacts for offline use and installs JVM applications
- Where it doesn't
- Supports Maven and Ivy package formats only
- Operates as a local developer tool rather than a hosted service
- Offline operation depends on cached dependencies
