Meet Zoomies: free, open-source GitHub Actions runners with a live web UI

Description and use

Zoomies simplifies self-hosted GitHub Actions runner management with autoscaling, a live web UI, and an automated migration wizard, reducing operational overhead and speeding repository migration to on-premises infrastructure.

Problem

Managing self-hosted GitHub Actions runners is operationally complex: tracking busy runners, scaling, cleaning up, and migrating existing repositories.

Outcome

Zoomies simplifies self-hosted CI by providing autoscaling, a unified UI, and automated migration, reducing operational overhead and enabling teams to move repositories to their own hardware efficiently.

Workflow

• Install Zoomies via curl script
• Configure GitHub App and create a runner pool
• Add hosts through the UI or CLI
• Run a workflow using a Zoomies label
• Monitor jobs and scaling in the web UI
• Use the migration wizard to update existing repositories' runs-on labels

Evidence

Zoomies is a free, open-source GitHub Actions runner fleet controller with ephemerals, autoscaling, a live web UI, and a migration wizard that opens reviewable pull requests.

Source

The migration wizard reads the workflows your GitHub App can access, maps supported hosted-runner labels to your pools, and shows the proposed changes before opening a pull request for each selected repository.
