Containers, VMs, or Kubernetes — built to your spec, managed end-to-end.

Ship faster with runners you control

GitHub-hosted runners are convenient, but they can become a bottleneck when you need predictable performance, private connectivity, or a build environment that isn’t “one size fits all”.

Our Managed GitHub Actions Build Service provides ephemeral build agents matched to your workloads: container runners for standard pipelines, dedicated VMs for isolation and performance, or Kubernetes-backed runners for scale. We tailor runner images, tooling, and runtime dependencies — including multi-architecture builds (x86 and Arm) and OS-specific requirements (Linux, Windows, macOS).

When your pipelines need private access (internal artefacts, registries, test systems), we enable secure connectivity so runners can reach private environments without exposing services to the public internet.

Start with a trial, then expand with add-ons as your teams and pipelines grow.

Current-Generation Performance

Latest-generation CPU architecture, high-performance memory, fast storage, and optimised cloud networking. Designed to keep services responsive under load.

Scale without bottlenecks

On-demand ephemeral runners

Spin up dedicated agents per job to remove queueing and reduce lead time.

Fit-for-purpose compute

Containers, VMs, or Kubernetes

Choose the execution model that fits your workloads and cost profile.

Cross-OS and architecture

Multi-platform builds

Build on Linux and Windows, with support for x86 and Arm workloads (and macOS where required).

Works with internal systems

Private network connectivity

Let runners reach private services securely for builds, tests, and deploys.

Faster feedback loops

Performance options

Select higher CPU, memory, and fast storage profiles for heavy builds and test suites.

Multi-platform builds

Built to your build spec

Works with most build stacks on GitHub Actions — from JVM and Node to Go, Python and native builds — plus container and IaC workflows.

Trusted by teams shipping globally

Used in production by organisations across retail, healthcare, finance, and open source.

Try Managed GitHub Actions Build first

Test jobs, private-network access, permissions, and runner patterns before changing your current self-managed runner setup.

1

Test the managed environment

Try representative jobs, private-network access, permissions, and runner patterns without touching your current runner setup.

2

Map the migration path

Review blockers, compatibility risks, runner-group changes, secrets handling, networking requirements, and operational dependencies.

3

Migrate with control

Move build execution, runner groups, networking, secrets handling, and workflow dependencies with a controlled migration and cutover plan.

4

Operate as a managed service

StackTrack manages runners, private connectivity, upgrades, support boundaries, and day-to-day reliability.

Frequently Asked Questions

Managed service path

How managed services start

Move into managed platform ownership without a risky handover or big-bang transition.

  1. 1

    Trial

    Start with a focused trial to validate fit, working model, access, communication, and the type of platform work StackTrack will own.

  2. 2

    Migration

    Move selected platform responsibilities, systems, runbooks, and operational workflows into the managed service. We review access, environments, delivery paths, support boundaries, documentation, and operational risks before ownership changes hands.

  3. 3

    Hypercare

    Run the early service period with closer attention, faster feedback, and tighter collaboration while the operating model stabilises.

  4. 4

    Ongoing service

    Continue with the agreed managed service model once responsibilities, communication paths, and operating rhythms are clear.
