ReviewOS and GitLab

GitLab is deliberately broad

Source, CI, registry, security scanning, deployments, and issue planning in one product. If you want that consolidated, GitLab is a coherent answer and this is not competing for that job.

• Built-in CI with runners you can host
• Container and package registries
• Security scanning and compliance features in the paid tiers
• A mature self-hosted story with real operational documentation

The cost of that breadth

A self-hosted GitLab is a system to operate: several services, a memory footprint that surprises people, and an upgrade path that needs planning. That is a fair trade for what it does, but it is a real cost.

What ReviewOS does instead

One process and one Postgres, with a status API your existing CI reports into rather than runners to operate. The complexity budget goes into review mechanics.

• Threads that survive rebases and force pushes
• Stacked pull requests with automatic retargeting
• Merge rules that report every blocker at once
• Diffs rendered on the server, against the merge base

Choosing between them

If you want one product to own the whole pipeline, GitLab. If you already have CI you are happy with and want the review half to be excellent while staying small to operate, this.
