Sandboxer vs GitHub Actions hosted runners
GitHub-hosted runners are fresh virtual machines that run a single Actions job and are then discarded; larger and GPU runners need Team or Enterprise Cloud. Sandboxer is not a CI service: sandboxes persist and can pause with memory saved. Pick GitHub Actions for workflows tied to your repositories; pick Sandboxer for long-lived agent and dev environments.

Where GitHub Actions hosted runners is strong
- Tight integration with GitHub repositories, with no setup for standard runners.
- Linux, Windows and macOS runners, including Arm and GPU larger runners.
- Docker preinstalled on the Ubuntu image and passwordless sudo.
- Larger runners offer static IPs.
Where Sandboxer differs
- Each job is capped at 6 hours and the VM is discarded; Sandboxer sandboxes can run with no time limit on a paid plan.
- Hosted runners bill per minute rounded up per job; Sandboxer bills per second and stopped sandboxes cost nothing.
- GitHub offers macOS, Windows and GPU runners; Sandboxer does not.
Pick GitHub Actions hosted runners if
- Your code and CI already live in GitHub.
- You need macOS, Windows or GPU runners.
- You want CI billed through your existing GitHub account with no separate vendor.
Pick Sandboxer if
- Need a long-lived machine you can stop, resume and reach over SSH or an HTTPS URL, not a machine that exists for one job.
- Want coding agents preinstalled and a prompt API, MCP server, SDKs and CLI for driving them.
- Need Docker, nested KVM and full root in a VM that can stop with memory saved and resume with processes running.
