Leverage Existing Kubernetes Infrastructure for Test Execution

The testing cloud earns its cost for real-device runs. For everything else, you are renting capacity you could run on the cluster you already operate.

The case for insourcing test execution

Organizations spending significantly on cloud testing platforms like Sauce Labs, BrowserStack, and LambdaTest should look at insourcing test automation onto their existing Kubernetes infrastructure. Insourcing means moving many executions off those clouds and onto on-premise infrastructure you already run.

Testkube works as a local orchestration platform, triggering your test automation tools inside your own Kubernetes infrastructure. It can still reach out to a cloud for the unique things only those platforms provide, like real-device testing. But the combination of Testkube and your own infrastructure lets you bring most automated testing in-house, with strategic, business, and QA benefits.

Where the cloud platforms came from, and where they don't fit

Cloud testing platforms gained popularity by offering an all-in-one way to run tests across many browser versions and real or virtual mobile devices. As the need for real-device testing declines for many teams, organizations are looking for alternatives that fit their DevOps strategy, in effect building a cloud-style automated testing setup on the Kubernetes infrastructure they already have.

Testkube is a cloud-native test orchestration and execution platform deployed in your own Kubernetes infrastructure. There is some overlap with the cloud platforms, but they serve different purposes depending on your DevOps, CI/CD, and testing strategy. So this is not a strict "Testkube vs cloud platform" decision: you can run Testkube alongside those platforms or replace them outright, based on what you need.

Supplement or replace: the advantages

Teams adopt Testkube alongside or in place of legacy cloud testing platforms for reasons that fall into three groups.

On strategy, Testkube is built on cloud-native principles and fits GitOps, event-driven architectures, and Kubernetes-based workflows, which keeps testing modern and scalable. It also enables shift-left testing: developers define and trigger tests independently of the CI/CD pipeline, running them manually, on a schedule, in response to Kubernetes changes, or as part of a build.

On business, running test automation inside your own Kubernetes infrastructure cuts reliance on expensive cloud testing services while keeping security and scalability in your control. And unified reporting gives you one pane of glass for every execution, so engineering teams pull results, artifacts, and logs from many tools in one place, which improves build quality, lowers cost, and shortens time to market.

On quality assurance, Testkube is tool-agnostic: as teams shift left, developers pick the best tool for the job, and Testkube orchestrates and scales any of them with no vendor lock-in, including calling the Sauce Labs API, running Postman for API tests, and more. That makes comprehensive end-to-end suites possible across commercial tools, open-source tools, and home-grown scripts together.

When to keep the cloud, and when to move

Cloud testing platforms still earn their place for teams that need standalone QA environments, real-device testing, or a waterfall-style process. For organizations on a cloud-native DevOps path, Testkube is a cost-effective, secure, and scalable alternative, working as either a complement or a replacement to those legacy platforms.

Why teams run this on Testkube

The spend on a testing cloud is easy to justify when you genuinely need its device matrix, and harder to justify for the bulk of automated runs that could execute on infrastructure you already pay for. Testkube lets you split that cleanly: keep the cloud for real-device or specialized runs, move everything else into your clusters, and orchestrate both from one place with one set of reports. You keep the capability you were paying for and stop paying for the part you do not need.

Bring testing in-house without losing reach

You do not have to choose between a costly testing cloud and giving up coverage. Testkube runs most of your automated tests on infrastructure you already own, still reaches the cloud for what only it can do, and reports it all in one place, so you cut cost and keep control.

Test faster, ship with confidence, and stay in control.
