GitLab

DevSecOps in one product: git, CI/CD, registry and issue boards, self-hostable when data residency demands it.

GitLab is the DevSecOps platform that put the whole lifecycle in one product: Git hosting, merge requests, CI/CD runners, a container registry, package registry, issue boards, security scanning and deployment environments, installable on your own hardware or consumed as SaaS. It is the self-hosted answer to a stack of separate tools.

Why founders use it: one URL and one permission model replace five vendors. CI pipelines run in the same place the code lives, and runners can be your own machines, which keeps builds inside your network. For teams with data residency requirements or a preference for owning the toolchain, a self-managed instance delivers enterprise features without enterprise procurement.

A realistic setup: projects with protected branches, CI defined in one file, runners on your infrastructure, the registry for images, and issue boards replacing a separate tracker. The built-in Pages feature can even host static sites.

Trade-offs: the application is heavy, self-hosting wants real resources and maintenance, and the SaaS free tier has limits on runners and features. The UI is denser than the competition's. Compare with GitHub for network effects and simplicity and with Gitea when the priority is a lightweight self-hosted forge.
