Engineering Guardrails for the AI Era.
Turn
postmortems, standards, eng wikis, checklists, AI pre-prompts, word
docs, conventions, compliance
into deterministic PR and AI-level enforcement
in minutes,
not quarters
Earthly Lunar: One Platform. All Your Standards. Automatically Enforced.
Lunar turns your engineering standards into self-enforcing guardrails that work across every tool, every team, every deployment.
Turn Docs and Checklists
into Code
Replace rubber-stamped checklists and Word docs with automated enforcement. Apply standards consistently across every deployment, every time.
From Ad Hoc
to In-Context
Transform ad hoc Slack reminders, email threads, and Jira tickets into automated guardrails enforced in PRs and AI coding agents. Never lose critical requirements in the noise.
One Click,
100+ Guardrails
Get instant value from day one. Start with battle-tested guardrails for quality, DevEx, operational readiness, security and compliance โ no need to build from scratch.

AI-Generated Code
Prompts are suggestions, not constraints. Lunar enforces hard rules through deterministic feedback in the AI's dev-test loop โ works with Claude Code, Codex, Cursor, and more.
Fast Track Post‑Mortems
68% of post-mortems are triggered by code and config changes.Google SRE Enforce new engineering behaviors at scale without the inefficiency of manual coordination.
Surface Issues Early,
Guide Proactively
Avoid surprising engineers with last-minute deployment blockers. Turn hated top-down mandates into helpful guidance that developers and agents actually follow.
From Ad Hoc Chaos to Instant Enforcement

Automated Guardrails that put control back into the hands of Platform Engineering
Define Standards Once
Write your testing, security, infrastructure, platform, and compliance policies as code. Turn post-incident action items into policies in minutes.
Enforce Everywhere
Automatically instrument all your codebases centrally. No migration or repo-by-repo integration required.
Real-Time Feedback
Developers and AI agents get instant feedback on standards adherence. Fix issues before merge, not at release time.
Complete Visibility
Executive dashboards showing standards coverage across every service. Continuously audit-ready.
Gradual Enforcement
Start with visibility, add scoring, then blocking. Bring teams along willingly.
Works With Your Stack
Works with GitHub, GitLab, and any CI/CD platform. Complements policy tools like OPA.
AI generates code fast. Guardrails ensure it ships right.
Lunar is what lets you confidently merge AI output at scale.
100+ Guardrails Included
Enforce standards across security, infrastructure, compliance, and operational readiness โ all from one system.
The ROI of Contextual Precision
You can't scale by broadcasting
every standard to
every engineer
The Broadcast Problem
Standards communicated
out-of-context
through mass channels
Contextual Feedback
Standards enforced exactly where and when they matter: in PRs and AI workflows
- Only shows relevant standards for this PR.
- Instant feedback in developer workflows.
- Zero context-switching.
