12 Best Cirun Alternatives for GitHub Actions in 2026
Cirun helps teams orchestrate self-hosted GitHub Actions runners across AWS, GCP, Azure, and on-premise environments, offering strong multi-cloud flexibility and free support for open source projects. However, pricing for private repositories scales by repository count rather than actual usage. You are also responsible for managing your own cloud accounts and networking, and Windows support is less mature than on some competing platforms.
The right alternative depends on your priorities, whether that is a fully managed service, stronger Windows support, or usage-based pricing instead of per-repository fees.
This guide explores 12 Cirun alternatives to help you find a runner solution that aligns with your infrastructure preferences and pricing model.
What makes a good Cirun alternative?
Cirun excels at multi-cloud self-hosted runners with infrastructure control and zero platform cost for open source projects. An alternative should deliver comparable cloud flexibility, similar self-hosted benefits, or address Cirun's repository-based pricing and management overhead while maintaining the control and cost optimization that makes Cirun valuable.
12 Best Cirun Alternatives
Cirun provides straightforward setup with repository-level .cirun.yml configuration and one-line workflow changes. Look for alternatives with similar ease of migration that won't force workflow rewrites or introduce compatibility issues.

Final thoughts
Cirun offers strong infrastructure control and free open source support, but per-repository pricing and management overhead are not ideal for every team.
If you prefer to stay self-hosted, RunsOn and Actuated maintain similar control. For less operational burden, managed platforms like Ubicloud, Depot, and BuildJet remove cloud management entirely.
Most alternatives provide usage-based pricing, stronger Windows support, or better cost efficiency. Many teams combine self-hosted and managed runners depending on workload needs. Your choice ultimately depends on infrastructure preference, Windows requirements, and pricing model.
