GitLab is right there. And overall provides a better product than GitHub, if nothing else on these two points:

* You can actually have an organisational structure (folders/namespaces), and projects can be moved around with automatic redirects. Also, inheritance of access controls, variables between the namespaces

* GitLabCI is organised in a way that makes supply chain attacks less of a risk. GitHub Actions takes the NPM/JS approach, where every step is an action, one you usually need to get off someone, with shoddy versioning, tons of transient dependencies, etc. In GitLabCI you can have templates, but you don't have to use an external template for every bit. It's shell scripting on top of containers, so you can have custom container images with your stuff, or custom scripts, or templates that bundle it all.
