Shockingly cheaper CI
SubscriptionWorkflow automationDevOpsCI26,774 impressions#4 of its week
RunsOn runs GitHub Actions jobs on on-demand AWS EC2 instances, cutting CI cost and latency.
- for
- Engineering teams that self-host CI on AWS and use GitHub Actions.
- pricing
- paid · free trial
- license
- MIT
Key features
- Dynamic instance selection — Specify CPU, RAM, architecture or GPU in a label and RunsOn launches the matching EC2 spot or on-demand instance.
- Fast job startup — Typical 30 s from queued to running; warm pools can reduce latency to under 6 s.
- Unlimited machine types — Any EC2 instance type, including x64, ARM64 and GPU, can be used per job.
- S3-backed caching — Add extras=s3-cache to use an unlimited S3 bucket in your VPC for cache storage.
- Nested virtualization — KVM for Linux and Hyper-V for Windows enable Android emulators, VM-based e2e tests and Windows containers.
- Per-job isolation — Each job runs on a fresh VM that is terminated when the job finishes, keeping data private.
Use cases
- Run large-scale test suites on high-CPU spot instances to reduce cost
- Execute GPU-intensive builds or ML training within CI pipelines
- Use ARM64 instances for cross-architecture testing without extra hardware
- Run Docker-in-Docker or nested VM workloads that need full VM access

- RunsOn vs Fluent CI: Fluent CI lets you write pipelines in TypeScript but runs on its own hosted infrastructure, not on your AWS account.
- RunsOn vs BuildShip: BuildShip provides a visual backend builder and AI assistance, not a low-cost EC2-based CI runner.
- RunsOn vs Daytona: Daytona creates dev environments on any infra, focusing on development rather than CI job execution.
- RunsOn vs Devzero: Devzero automates releases but does not replace GitHub Actions runners with spot EC2 instances.
RunsOn FAQ
Will my existing GitHub Actions workflows break?+
No. The runner images are ported from GitHub’s own templates, so actions, cache steps and secrets work unchanged; you only change the label.
How fast does a job start?+
About 30 seconds from queued to running on a fresh instance; warm pools can bring it under 6 seconds.
Does Docker work inside the runners?+
Yes. Each job gets a full VM, so Docker, Docker-in-Docker and Compose behave as on any EC2 instance.
Is it safe to run inside my AWS account?+
Each job runs on a fresh EC2 instance that is destroyed after the job; code, secrets and caches never leave your account.
What does RunsOn charge beyond the license?+
Only your AWS bill for the spot/on-demand instances, S3 cache bucket and EBS volumes; RunsOn adds no compute markup.
What happens if spot capacity is unavailable?+
RunsOn falls back to on-demand with a 2–3 s launch penalty and retries interrupted jobs once on-demand by default.
