# Choosing Managed GitHub Actions Runners for Your Team

Managed GitHub Actions runners suit teams that want another provider to operate their CI execution infrastructure while keeping workflows in GitHub Actions. Choose a provider by supported workloads, cost per successful workflow, security boundaries, and migration effort. Validate those requirements with your own jobs before moving production deployment workflows.

A growing team does not automatically need a new runner provider. First identify the constraint: queue time, a rising bill, memory limits, missing platforms, or engineering time spent maintaining runners. The right choice addresses that constraint without adding a larger operational burden.

## What are managed GitHub Actions runners?

Managed GitHub Actions runners are execution environments that a provider provisions and maintains for your GitHub Actions jobs. Your repository keeps its workflow definitions, while the provider supplies the machines on which selected jobs run.

GitHub-hosted runners are one managed option. Third-party services offer other infrastructure and operating models. Self-hosting gives your team responsibility for its runner environment; GitHub documents that self-hosted runners can use infrastructure you manage and require maintenance. See its [self-hosted runner reference](https://docs.github.com/en/actions/reference/runners/self-hosted-runners) when assessing that responsibility.

Bring-your-own-cloud, or BYOC, is another model to evaluate: runner infrastructure operates in your cloud account, with the exact division of management responsibilities depending on the product. It can suit organizations that need control over cloud resources or access to private services. Include cloud configuration, upgrades, incident handling, and billing ownership in that evaluation.

Use this table to narrow the decision before comparing individual plans:

| Your main requirement | Option to evaluate first | What to verify |
| --- | --- | --- |
| Keep a working CI setup with minimal change | GitHub-hosted runners | Existing platform support, included usage, limits, and actual workflow costs |
| Reduce runner administration for supported Linux jobs | A managed provider such as 9apes | Labels, image compatibility, isolation, billing, and support |
| Place compute in your own cloud account | A BYOC service | Cloud permissions, network design, total infrastructure cost, and maintenance ownership |
| Use specialized images or infrastructure | Self-hosted runners or a suitable BYOC service | Patching, scaling, cleanup, and capacity during failures |
| Build for several operating systems or architectures | A provider with confirmed coverage | Availability for each required platform before migration |

The [runner comparison hub](/compare/) and [RunsOn comparison](/compare/runs-on/) can help frame provider questions. Treat them as a shortlist aid, then verify each requirement against current documentation and a pilot.

## How should you compare GitHub Actions runner costs?

Compare the total cost of delivering a successful workflow, not only the advertised runner-minute rate. A lower rate has limited value if the workflow needs more execution time, fails more often, or requires substantial maintenance.

Use a consistent measurement period and calculate:

**Cost per successful workflow = total CI cost during the period / successfully completed workflows during the period.**

For this calculation, include billed execution across all jobs and retries, applicable storage and network charges, and an agreed estimate of runner administration time. Keep infrastructure charges separate from labor so both remain visible. Count success consistently, including the same test and artifact requirements for every option.

Also report completion time and queue time separately. They affect developer experience even when they do not appear as a direct line item. A workflow with multiple parallel jobs can have a short wall-clock duration and still consume substantial billed compute.

Use representative workloads: a routine pull request, a dependency-heavy test suite, and a build that produces your normal artifacts. For compile-heavy jobs, the [C++ and Bazel runner guide](/blog/github-actions-runners-cpp-bazel-builds/) explains how to separate runner resources from caching and remote execution. Keep repository state, dependencies, and cache conditions comparable. Record failures rather than dropping them from the results.

For an editable checklist that includes idle capacity and engineering effort, use the [self-hosted CI cost model](/blog/self-hosted-ci-cost/).

Read [GitHub's current runner pricing reference](https://docs.github.com/en/billing/reference/actions-runner-pricing) and the [9apes pricing page](/pricing/) when building the estimate. Check your account's applicable usage allowances and billing terms. Standard GitHub-hosted runners can have included usage or free eligible public-repository usage. GitHub larger runners are always charged, including in public repositories, and cannot use included minutes. Avoid basing a decision on a remembered rate or a single unusually fast run.

## What does ephemeral runner isolation protect?

Ephemeral runner isolation limits the lifetime and sharing of a job's execution environment. It does not replace workflow permissions, secret handling, dependency controls, or rules for executing untrusted code.

Ask what is created per job: a container, a virtual machine, or another boundary. Then ask what survives completion. Caches, uploaded artifacts, logs, external services, and credentials can have lifetimes beyond the runner itself. An environment that disappears after a job should not be interpreted as a promise that every related data copy disappears.

The [9apes security page](/security/) documents a Firecracker microVM for each job, with the microVM and its state destroyed when the job ends, and no shared kernel between jobs. It also states that SOC 2 is in progress. That status is not a completed certification.

Evaluate these facts against your own requirements. Confirm access controls, required evidence, data handling, and how privileged build operations are supported. For deployment jobs, review the permissions of the workflow and its credentials independently of the runner decision.

## When is 9apes a fit, and how should you migrate?

9apes is worth evaluating for teams running Linux x86_64 GitHub Actions jobs that want managed execution with documented per-job microVM isolation. Start by confirming compatibility with its public Ubuntu 24.04 runner labels in [Available Runners](/docs/available-runners/). Linux arm64, Windows, and macOS require contacting 9apes about availability; do not assume they are available through the public Linux labels.

GitHub-hosted runners may remain the better fit when your current setup meets platform, cost, and operational requirements. A BYOC option may suit a team whose deciding requirement is execution within its own cloud account, provided the team accepts the associated responsibilities.

For a 9apes pilot, follow the [quick-start guide](/docs/quick-start/): install the GitHub App for selected repositories and change one low-risk job's `runs-on` label. Preserve its previous value. Compare the same checks, artifacts, cache behavior, costs, and completion times over several representative runs.

Set acceptance criteria before the pilot. Include functional correctness, acceptable failures, cost, and platform compatibility. If those criteria are not met, restore the previous runner label and verify the workflow again. Keep later migrations incremental, especially where deployment credentials or private network access are involved.

Review the [supported runners](/docs/available-runners/) and [current pricing](/pricing/), then choose one existing workflow to evaluate.
