The Open Source CI/CD framework that runs anywhere
Why Earthly?
With Earthly, all builds are containerized, consistent, and language agnostic.

Easy to Understand
Write once, run anywhere: Your laptop, remote, or any CI
Super-simple, Super-powerful
It's like Dockerfile and Makefile had a baby ❤️
Earthly was engineered for readability. Most engineers are able to read an Earthfile without any prior knowledge. We took some of the best ideas from Dockerfiles and Makefiles and combined them into one specification.

Built-in caching for more speed
FROM golang:1.13-alpine3.11
RUN apk --update --no-cache add git
WORKDIR /go-example
BUILD +build
BUILD +lint
COPY main.go .
RUN go build -o build/go-example main.go
SAVE ARTIFACT build/go-example AS LOCAL build/go-example
RUN go get
COPY main.go .
RUN golint -set_exit_status ./...
Building things
Easily reproduce CI failures
Earthly builds are self-contained, isolated and repeatable. Regardless of whether Earthly runs in your CI or on your laptop, the build will run the same way. This allows for faster iteration and easier debugging. Unlock your team's full productivity by eliminating "works on my machine but not in CI" blockers. No more git commit -m "try again".
Developer friendly like a build system, versatile like a CI
Parallel by default 🚀
Whenever possible, Earthly automatically executes targets in parallel and makes maximum use of cache. Earthly also has powerful shared caching capabilities, to speed up builds in sandboxed environments, such as GitHub Actions.
If your build has independent steps, Earthly will:

FROM golang:1.13-alpine3.11
WORKDIR /proto-example
FROM namely/protoc-all:1.29_4
COPY api.proto /defs
RUN --entrypoint -- -f api.proto -l go
SAVE ARTIFACT ./gen/pb-go /pb AS LOCAL pb
COPY go.mod go.sum .
RUN go mod download
COPY +proto/pb pb
COPY main.go ./
RUN go build -o build/proto-example main.go
SAVE ARTIFACT build/proto-example
Repeatable builds that work everywhere:
Local, Remote, or CI
When the environment is decoupled from the build execution, the possibilities are endless. Run the build locally, close to where you make edits to your code, or run the build on a remote cloud worker for maximum performance, or run the same build in the CI of your choice. No need to configure language-specific tooling, install additional dependencies, or ensure that the build scripts are compatible with your OS. Earthly gives you consistent, repeatable builds regardless of where the execution takes place. The world is your oyster. 🦪
Works with the build tools you know and love 🔨
Unlike some opinionated build systems, Earthly allows you to use the compiler and build tooling specific to your programming language of choice. You don't need to completely rewrite your builds, nor replace your package.json, go.mod, build.gradle, or your Cargo.toml. You can use Earthly as a wrapper around your existing tooling, and benefit from repeatable builds effortlessly.
Building things
IMPORT AS static

FROM node:13.10.1-alpine3.11
WORKDIR /example-multirepo
RUN npm install -g http-server
COPY static+html/* ./
COPY js+build/* ./
ENTRYPOINT ["http-server", "."]
SAVE IMAGE --push earthly/examples:multirepo
Reuse, don't repeat ♻️
Reference builds, recipes, images and artifacts from another build in a single line. Earthly is cache-aware, based on the Git commit hash of the referenced repository. Combined with shared caching, you can create vast and efficient build hierarchies that only execute steps impacted by your changes. Earthly builds are performant in either monorepo or polyrepo setups and do not suffer from bloated context transfer issues specific to some Dockerfile setups.
Strong Community
Open projects benefit from a collaborative community. Earthly encourages contributions.

Matt Klein
Creator of Envoy Proxy
Earthly is a pragmatic and incremental solution to a thorny problem that all organizations face. I'm extremely excited about Earthly bringing this functionality to existing container based build systems without requiring an extremely expensive retooling effort on top of something like Bazel.
Envoy is an open source edge and service proxy, designed for cloud-native applications.
Florian Leibert
Founder of D2iQ
Large organizations like Google or Twitter have solved these problems internally in a way that is idiosyncratic to their engineering processes. Earthly is the first solution to bring the power of repeatable builds at scale to market in a packaging that can fit all organizations.
D2iQ (formerly Mesosphere) simplifies enterprise Kubernetes in production at scale.
