GitLab is a complete DevOps platform. GitLab gives you a complete CI/CD toolchain right out of the box. One interface. One conversation. One permission model. GitLab is a complete DevOps platform, delivered in one application. It fundamentally changes the way Security, Development, and Ops teams collaborate. GitLab reduces development time and costs, reduces application vulnerabilities, and speeds up software delivery. It also increases developer productivity. Source code management allows for collaboration, sharing, and coordination across the entire software development team. To accelerate software delivery, track and merge branches, audit changes, and enable concurrent work. Code can be reviewed, discussed, shared knowledge, and identified defects among distributed teams through asynchronous review. Automate, track, and report code reviews.

When engineering standards live in wikis, tickets, and CI templates, they are difficult to apply consistently across a growing software organization. Earthly Lunar gives platform engineering teams a central way to enforce those standards across different repositories, pipelines, and developer workflows. It gathers evidence from source code and CI/CD execution, normalizes it into a service-level view, and runs deterministic guardrails against that data. A guardrail might require test coverage, an approved dependency, an SBOM, or a deployment check. Teams can introduce policies in a visibility-only mode, surface findings on pull requests, and move to blocking checks when ready. Developers get actionable feedback on proposed changes while platform leaders see adoption across the organization. Lunar includes a library of 200+ guardrails and supports custom policies for company-specific requirements, including lessons from incidents. Continuous results provide a record of what was checked and when, reducing the work of gathering compliance evidence.
