Earthly

Engineering guardrails for the AI era

Overview

What Earthly does

Earthly addresses the challenge of maintaining consistent engineering standards as teams scale and AI agents become part of development workflows. The Earthly Lunar platform transforms documentation like AGENTS.md files, engineering wikis, incident postmortems, and compliance mandates into enforceable policies that run as code throughout the development lifecycle. Rather than relying on scattered standards communicated through emails and Slack, Lunar centralizes enforcement so any standard, process, or incident response can be converted into a guardrail across every repository in minutes. The platform applies the same guardrails deterministically to both human developers and AI coding agents, ensuring consistent behavior across different tools and development stages. Founded in 2020 by Vlad A. Ionescu, Earthly built on the success of the open-source Earthfiles tool (12,000 GitHub stars) and launched Lunar in 2025 after conducting over 100 enterprise interviews. Earthly is based on the vision of building the developer infrastructure teams always wished existed.

What people use it for

  • Enforcing engineering standards across AI and human developers
  • Automating incident response procedures across all repositories
  • Embedding compliance requirements into development workflows
  • Standardizing build processes with Earthfiles

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Earthly.

  • Pricing model not published; requires sales contact
  • Earthly Lunar is a recent launch (2025) with limited track record
  • Primarily GitHub-focused; limited integration with other platforms
  • No public documentation on pricing or feature tiers
