Earthly vs Open Build Service

Earthly Lunar monitors software development activity and applies engineering policies across developer and AI workflows. It collects structured metadata from source repositories and CI/CD pipelines, then evaluates it against policies an organization defines. Lunar can be added to existing CI/CD pipelines without YAML changes or wholesale pipeline rewrites. Its guardrails can run while code is authored, on pull requests, and at deployment gates; enforcement can progress from draft and scoring to comments or blocking pull requests and deployments. Earthly lists more than 200 prebuilt guardrails for testing, security, compliance, and operational readiness. The integrations page lists 66 integrations, with Bash-script options for custom collectors and catalogers. Documentation includes a SQL API for engineering data and a CI agent that can run on self-hosted runners and is compatible with major CI vendors. Earthly says its services and databases are hosted on AWS in the United States, data is encrypted at rest and in transit, and it has SOC 2 Type II compliance. Earthfiles, an open-source portable build syntax, remains available. Earthly says the company was founded in 2020 and Lunar launched in 2026.

Open Build Service (OBS) builds and distributes binary packages from source code in a consistent, reproducible way. Each package is built in a fresh jailed environment; when a build succeeds, OBS rebuilds packages that depend on it. The service can release packages, updates, add-ons, appliances, and complete distributions for different operating systems and hardware architectures. Documented package formats include RPM, DEB, and Arch, with recipes in formats such as spec, dsc, KIWI, and mkosi. Teams can use access controls, branches, merge requests, and submission reviews to coordinate work. GitHub.com and GitLab.com integrations are supported, as are self-hosted GitHub, GitLab, and Gitea instances when network connectivity works. The API gives clients and external services access to OBS resources, while the osc command-line client can edit sources and metadata, start builds, and gather results. OBS is GPL-licensed free software, available on a reference server for open-source developers or for installation on users’ own hardware or in a data center. The listed plan is free.
