Earthly
What it is
Earthly Lunar is a guardrails platform that 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. Teams can add Lunar to existing pipelines without YAML changes or wholesale rewrites. Guardrails can operate during code authoring, on pull requests, and at deployment gates; enforcement can progress from draft and scoring to comments or blocking pull requests and deployments. Lunar includes more than 200 prebuilt guardrails for testing, security, compliance, and operational readiness. Its integrations page lists 66 integrations, and Bash scripts can be used to build custom collectors and catalogers. Documentation lists a SQL API for engineering data and a CI agent that can run on self-hosted runners and works with major CI vendors. Earthly also maintains Earthfiles, an open-source syntax for portable, language-agnostic builds. Earthly says its databases are in the United States and encrypted at rest, with TLS/SSL protecting data in transit; it reports SOC 2 Type II compliance. The product is listed as free with a free plan.
