Earthly

Reproducible build system combining Dockerfile and Makefile syntax

Infrastructure & DevOpsFreemium

Earthly is an open-source build automation tool that creates perfectly reproducible builds by running every build step in a container, eliminating 'works on my machine' problems in CI/CD pipelines. Its syntax combines the best of Dockerfile (layer-based caching, container isolation) with Makefile (named targets, dependency graph) into a single Earthfile. Earthly integrates with any CI provider and supports remote caching and parallel execution, making it suitable for complex monorepos where dependency tracking and cache efficiency are critical to maintaining fast build times.
