Earthly is a containerized build automation tool for developers and DevOps teams who need reproducible local and CI builds. Its Earthfile syntax...
Pros
- Reproducible builds run consistently on local machines and CI runners
- Container-based syntax reduces differences between development and CI environments
- Built-in parallelism and caching can shorten repeated builds
Cons
- Smaller ecosystem and user community than Jenkins, GitHub Actions, or Bazel
- Container-first execution can add overhead for lightweight tasks
- Earthfile syntax requires migration from existing pipelines and build systems

- Supports concurrent and multi-platform container builds
- Integrates with Docker Buildx and common CI providers
Cons
- Adds a hosted-service dependency to the container build pipeline
- Less flexible than running and modifying your own BuildKit infrastructure

Pros
- Programmable pipelines offer more flexibility than Earthly's declarative Earthfiles
- Portable container execution works across CI providers and local environments
- Strong SDK support for Go, Python, TypeScript, and other languages
Cons
- Programming-language pipelines can be more complex to review than Earthly files
- You must manage more runtime and SDK details than with a conventional CI YAML file

Docker
Docker Build Cloud is a hosted build service for Docker images that runs builds on cloud builders while integrating with Docker Desktop...
Pros
- Deepest integration with Docker Desktop, Buildx, and the Docker ecosystem
- Supports shared cache and multi-platform builds across development and CI
- Offers a familiar workflow for teams already using Docker
Cons
- Less Dockerfile and builder customization than self-hosted BuildKit
- Usage charges can be difficult to predict for high-volume pipelines
