The Real Cost of Playwright

Free frameworks aren’t free

Playwright, Cypress, Selenium are all powerful tools. They are widely used, well supported, and importantly, free to get started with. That is a big part of their appeal.

There is no upfront cost, local execution is effectively free, and it is easy to get your first tests running quickly. At this stage, test automation feels like a very low-cost decision.

And for small test packs, it often is.

But that is not where most teams stop.

Playwright is a great example

Playwright is one of the strongest frameworks available today. It is fast, flexible, and gives engineering teams a high level of control over how tests are written and executed.

If your team is comfortable writing and maintaining test code, it will take you a long way.

But it is still just a framework. It helps you write tests, it does not solve everything around them.

Where the cost actually starts

The moment tests become part of your delivery process, the requirements change. You are no longer just running tests locally, you need reliable execution inside CI/CD, consistent environments, and fast feedback across the team.

That usually leads to remote execution.

At first, this looks completely reasonable. The test pack is still small, the number of runners is low, and the cost is there but not particularly concerning. Most teams pick one of the well-known options and move on.

Then the pack grows

Test packs do not stay small. As products grow, so does the need for coverage. More features, more user journeys, more edge cases.

This leads to longer run times, slower feedback, and pressure to run tests in parallel.

The natural solution is to add more runners. It works, and in the short term it solves the problem.

This is where the cost shows up

What started as a small monthly cost begins to scale with your test pack. It is not unusual to go from needing 20 runners to needing 200 over time.

At that point, the cost is no longer background noise. It becomes a noticeable part of the QA budget.

And it is not just runners driving that cost.

You have built a system

To make Playwright work effectively at scale, teams end up building and maintaining a full system around it.

That typically includes test runners and infrastructure, parallelisation strategies, CI/CD integrations, reporting and visibility, debugging workflows, and environment management.

None of this is unexpected, but it adds up. You did not just adopt a framework, you committed yourself to building a full system.

Why teams stay stuck

By the time this becomes a problem, there is already a significant investment in place. There is a growing test pack, established workflows, and internal knowledge tied to the setup.

Changing direction at this point is difficult. It means rework, disruption, and risk.

So the easiest option is to keep scaling what already exists. In practice, that usually means increasing spend rather than rethinking the approach.

Free is not free

Frameworks like Playwright remove the cost of getting started, but they do not remove the cost of running and maintaining test automation at scale.

You still need to run the tests, maintain the system, and support the people working with it.

Those costs are not avoided, they are just delayed.

What is worth thinking about earlier

Before committing to a testing approach, it helps to think beyond the first set of tests.

It is less about how quickly you can write tests, and more about what the system looks like once it grows.

What does this look like at 200 tests, or 2,000? How does execution scale? Who owns the infrastructure? How much time goes into maintenance?

These questions matter more than the initial framework choice.

Different ways to approach it

There is no single correct approach, but most teams end up in one of three models.

Some build everything internally. This gives full control, but comes with higher engineering cost and ongoing maintenance.

Some rely on third-party execution providers. This is faster to get started and easy to scale, but costs tend to grow over time.

Others use more integrated systems, where execution, reporting, and scaling are built in. This reduces the amount of infrastructure to manage and makes costs more predictable.

Each approach has trade-offs, but they lead to very different outcomes as you scale.

Why this matters

This is not just a tooling decision. At some point, these costs are reviewed at a team or department level.

When they are, the response is not always better tooling. It can be reducing scope, slowing delivery, offshoring work, or cutting headcount.

Understanding the real cost early helps avoid those decisions later.

Final thought

Playwright is a strong foundation, and for many teams it is the right starting point.

But it is still just that, a starting point.

The real cost of test automation comes from everything built on top of it. Teams that understand that early are in a much better position as they scale.
