How does AlloyCI compare to GitHub Actions?

AlloyCI uses GitLab's CI runner and YAML syntax, offering advanced features like artifact passing and auto-scaling, but requires self-hosting, whereas GitHub Actions is natively integrated with GitHub and easier for beginners. It's a trade-off between power and convenience.

Can I use AlloyCI with private GitHub repositories?

Yes, AlloyCI integrates with GitHub repositories, including private ones, to run CI/CD pipelines and report statuses, as implied by its goal to serve GitHub users without platform restrictions.

How to set up auto-scaling with AlloyCI?

Auto-scaling is supported via the Alloy Runner, which can create and destroy runners on demand; detailed configuration is available in the linked documentation in the README for on-demand resource management.

What are the main limitations of AlloyCI?

Key limitations include incomplete deployment features like environments and Review Apps, the need for self-hosting with technical setup, and reliance on a forked runner that may not update as frequently as GitLab's official runner.

Is AlloyCI good for large teams?

It can handle complex pipelines with auto-scaling and advanced CI, but the self-hosted setup requires infrastructure management, making it better for teams with DevOps expertise rather than those wanting hands-off SaaS.

How to migrate from Travis CI to AlloyCI?

You'll need to convert Travis CI YAML to .alloy-ci.yml syntax, which is similar to GitLab CI, set up an AlloyCI instance, and configure GitHub integration, leveraging its artifact and cache features for similar workflows.

What is AlloyCI?

AlloyCI is a Continuous Integration, Deployment, and Delivery platform written in Elixir that bridges GitLab's CI runner with GitHub repositories. It enables GitHub users to run CI/CD pipelines using GitLab's runner technology without switching to GitLab, reporting pipeline statuses directly to GitHub pull requests, branches, and commits.

Target Audience

GitHub users and teams seeking a free, open-source CI/CD solution that replicates GitLab's pipeline capabilities, particularly those familiar with GitLab CI syntax or wanting to avoid commercial services.

Value Proposition

Developers choose AlloyCI for its unique integration of GitLab's powerful CI runner with GitHub, offering advanced features like artifact management, auto-scaling, and deployment triggers at no cost, unlike many paid alternatives.

Teams wanting a free, open-source alternative to commercial CI/CD services like Travis CI or CircleCI.

Projects requiring advanced CI features such as artifact passing between jobs, secret variables, and build caches.

Environments that benefit from auto-scaling runners for on-demand job execution.

Workflows that integrate pipeline status reporting directly into GitHub pull requests and commits.

Deployment pipelines with manual triggers or auto-deploy capabilities for continuous delivery.

Not Ideal For

Teams already using GitLab CI who don't need GitHub integration.
Projects requiring out-of-the-box Review Apps or multi-environment deployments, as these are listed as incomplete in the README.
Organizations seeking a fully managed SaaS CI/CD with zero infrastructure setup and maintenance.
Developers unfamiliar with Elixir or Docker who prefer simpler, guided CI solutions like GitHub Actions.

Pros & Cons

Pros

GitLab Runner Compatibility

Leverages the robust GitLab CI Runner for job execution, including Docker support and auto-scaling via the forked Alloy Runner, as specified in the README's features.

Seamless GitHub Integration

Reports pipeline statuses directly to GitHub pull requests, branches, and commits, enabling native feedback without platform switching, a core goal highlighted in the description.

Advanced CI Features

Supports artifact management, build caches, secret variables, and job dependencies via .alloy-ci.yml, matching many of GitLab's capabilities for complex workflows.

Cost-Effective Open Source

Provides a free alternative to commercial CI services, with the philosophy to offer GitLab EE-like features without cost, as stated in the goals.

Cons

Incomplete Deployment Features

Lacks support for environments and Review Apps, which are explicitly listed as stretch goals or not yet implemented in the deployment functionality section of the README.

Complex Self-Hosting Setup

Requires installation and configuration of Elixir, Docker, and a database, as per the contribution guide, which can be daunting compared to plug-and-play SaaS options.

Dependency on Forked Runner

Relies on the Alloy Runner, a fork of GitLab CI Runner, which might lag behind upstream updates or have limited community support compared to mainstream tools.
