Earthly Has a Free API: Repeatable CI/CD Builds That Work Everywhere

Earthly is a build automation tool that combines the best of Makefiles and Dockerfiles. It gives you repeatable, containerized builds that work the same on your laptop and in CI. What Is Earthly? Earthly provides a syntax that combines Dockerfile and Makefile concepts into Earthfiles. Every build step runs in a container, so builds are reproducible regardless of the host environment. No more 'works on my machine' problems.
