A curated list of awesome self-hosted GitHub Action runner solutions in a large comparison matrix
The purpose of this repository is to provide an overview on self-hosted runner solutions for GitHub Actions compared by various criteria. There is no rating implied as the importance of the various categories differ from use case to use case. Data can be out of date, so if a certain feature is told to be missing, please double check whether this is still the case.
During my research, I stumbled over dduzgun-security/github-self-hosted-runners with tips on what to consider when using self-hosted runners by yourself.
The virtual environments provided by GitHub Action managed runners like
ubuntu-latest contain a LOT of pre-installed tools already. If all of those tools were installed in your self-hosted runner, this would result in images > 18 GB. In many cases where you have a better picture for which purposes/platforms you will use your self-hosted runners, this is probably not what you want for performance and maintenance reasons. All of the self-hosted solutions compared allow to define custom images with custom tooling.
If you like to test your custom images with your Actions workflows locally before you expose them to your end users at large scale, you can use nektos/act to specify your own Docker image for a specific runner label using the -P option, see a more complex example here.

Specifies whether the self-hosted runners are running on a container, Kubernetes cluster or virtual machine. Virtual machine based runners typically have some cloud specific dependencies.
While GitHub.com is supported by all self-hosted runner solutions evaluated, not all of them support GitHub Enterprise Server yet (although supporting GitHub Enterprise Server is often just a matter on changing the API endpoint).
Self-hosted runners can be registered on the repo, org and enterprise level and may register with custom labels inside runner groups - but not all runner solutions provide support for all those options.
Some self-hosted runner solutions have the ability to specify how many runners of a certain kind should be launched and whether crashed runners should be restarted.
Some self-hosted runner solutions have the ability to scale automatically with the amount of pending jobs, busy runners, CPU utilization, ...
While self-hosted action runners can support Linux (x86, ARM, ARM64), Mac and Windows - most self-hosted runner solutions are restricted to a subset of those architectures
Not all runner solutions remove themselves after they have been deleted, which can be problematic, especially, if combined aith auto-scaling capabilities.
Some runner solutions provide a personal access token (PAT) or OAuth token directly to the runner so that it can register itself. This imposes the risk of a malicious job trying to steal the token and use it to elevate its permissions. Solutions that only pass a runner token to the actual runners are preferred from a security perspective.
While self-hosted runner provide some isolation between jobs, it is the responsibility of the job to clean up in most cases. Some self-runner solutions automatically de-register and clean-up runners after every build to avoid any interference between jobs.
Calls out any special privileges (like Kubernetes cluster admin, Docker privileged mode) needed to run or install the solution.
Some centralized runner solutions rely on the ability to receive web hook events from GitHub about new jobs. This approach might not be feasible for some installations, although a reverse proxy may help.
GitHub's own, hosted runners have a lot of software already pre-installed. Most container based solutions follow a different philosophy where only a minimum amount of software is pre-installed.
While the number of contributors is not the only criteria, it is typically a good indicator for the maturity of a solution.
Some runner solutions have add-ons that allow end users to stand up new runner groups in a self-service fashion, e.g. via IssueOps.
Some solutions require certain central components to be up and running all the time or at least one idle runner to allow scaling up properly - this category provides an idea of what is needed in terms of components, not concrete $$$ costs.
