Earthly

Earthly is an automated engineering guardrails platform that transforms documentation, standards, and postmortem action items into enforceable code. Instead of relying on manual coordination and hoping engineers follow checklists, Earthly automatically applies standards across every tool, repository, and deployment. It works by converting your engineering requirements into deterministic rules that provide immediate feedback during development.

The platform stands out by integrating directly into developer workflows, providing instant feedback in pull requests and to AI coding agents. It works with popular AI coding tools like Claude Code, Codex, and Cursor, ensuring that AI-generated code meets your organization's standards. Earthly comes with pre-built guardrails for quality, developer experience, operational readiness, security, and compliance, allowing teams to get value immediately without building from scratch.

Engineering managers and platform teams benefit most from Earthly, particularly those managing large codebases with multiple teams. It helps prevent recurring incidents by automatically enforcing lessons learned from postmortems, reduces manual coordination overhead, and provides visibility into adherence across the organization. The tool is especially valuable for organizations using AI coding assistants, as it ensures generated code meets quality and security standards without manual review.
