Comparison

ZeusQA vs Playwright: describe the test, or write the test

A free library you write tests in, against a hosted service you describe tests to.

The short answer

Playwright is a free open-source library you write tests in; ZeusQA is a hosted service you describe tests to. Playwright is faster, deterministic, runs in CI and covers Firefox and WebKit. ZeusQA needs no code, reads the screen, and reports console errors and failed requests you did not think to assert on.

Side by side

Playwright: Apache-2.0 browser automation library and test runner from Microsoft. Every cell below traces to a source at the foot of this page, and the rows where ZeusQA is worse are not softened.

What it isHosted service. Give it a URL and a plain-English test; a model drives a real Chromium and files a report.Open-source library and test runner for Chromium, Firefox and WebKit through one API.
Licence and ownerProprietary SaaSApache-2.0, maintained by Microsoft
How a test is writtenA paragraph of EnglishCode — TypeScript/JavaScript, Python, .NET or Java. codegen records your actions and writes it for you.
SetupNone. Sign up, paste a URL.npm init playwright@latest, browsers download, and you own a suite from then on.
PriceFree for 3 runs. Pro $39/mo for 300 runs. Team $149/mo for 1,500.Free. No paid tier and no vendor-hosted service; you pay for your own CI compute.
BrowsersChromium onlyChromium, Firefox and WebKit, headless or headed, on Linux, macOS and Windows
Deterministic rerunsA run re-plans each time, so the same prompt can take different paths. Its exported Playwright test replays the same steps every time, with no model.Yes. The same script runs the same way.
SpeedAbout a minute for a typical flowMilliseconds to seconds per test, once it is written
MaintenanceNo stored selectors. The prompt is the artefact.Selector and script maintenance is the main long-run cost. The Healer agent repairs failing tests automatically.
AssertionsNamed checks the model derives from your prompt. No assertions on databases, email inboxes or API payloads.Anything expressible in code: API calls, database access, fixtures, custom matchers.
Findings you did not ask forConsole errors, uncaught page errors, failed or 4xx/5xx requests and passive security checks (headers, cookies, mixed content, leaked secrets) on every run, each with a severityExactly the assertions you wrote. Traces, video and screenshots are configurable.
Debugging artefactPer-step screenshots and a live browser view. Session video on Pro and Team, when turned on.The trace viewer, which is the best debugging artefact in the category
CIA run on each pull request with a preview URL, through the GitHub App, reported as a comment for each commit. No CLI.First-class. Running in CI is the normal way to use it.
Scheduling and alertingPro and Team: schedules hourly, daily, on weekdays or weekly, with email when a run fails. Free has none.Not built in either — you use your CI scheduler, or a monitoring tool
Works against localhostYes: one command connects your computer, and tests run in your Chrome against localhost, VPN-only staging and your logins.Yes, anywhere your machine or runner can reach
AI featuresThe product is the model. An MCP server lets Claude Code or Cursor read findings, start tests and check its own fixes.Three agents: Planner ('explores the app and produces a Markdown test plan'), Generator ('transforms the Markdown plan into the Playwright Test files') and Healer ('executes the test suite and automatically repairs failing tests'). Plus an official MCP server.

When to pick Playwright instead

These are real recommendations. If one of them describes you, Playwright is the better tool and you should use it.

  • You need Safari or Firefox coverage. This is the clearest case and it is not close.
  • You need a test that gates merges. ZeusQA runs on pull requests through its GitHub App, but the model re-plans every run, so its verdict is not a repeatable gate.
  • You need a deterministic pass or fail you can trust to mean the same thing twice.
  • You need to assert on something the UI does not show: a database row, an email that was sent, the shape of an API response.
  • You are running hundreds of tests a day. At that volume a free library beats any per-run price.
  • You already have a suite that works. Nothing here is a reason to throw it away.

When ZeusQA is the better fit

  • The test does not exist yet, and writing it will take longer than running it.
  • You want a look at a flow nobody owns, on staging, right now.
  • You care about what was on the screen and in the console, not only the assertions you thought to write.
  • Nobody on the team writes Playwright, and you would rather they did not have to.
  • You want the same flow checked at three device sizes without maintaining three projects.

Using both

For most teams the answer is both: Playwright for the regression suite that gates merges, ZeusQA for exploratory passes and post-deploy checks on flows nobody has scripted. A ZeusQA run is also a cheap way to write the script: export it as a Playwright test and add it to the suite — the same job Playwright's Planner and Generator agents do from the other direction.

Questions

Is ZeusQA built on Playwright?

Yes. Runs drive a real Chromium through Playwright, and the model writes short Playwright scripts for each step.

Can ZeusQA export a Playwright test?

Yes. Every run is also a plain @playwright/test file, one test.step per browser step. View, copy or download it from the run page, replay it there with no model, or run it in your CI. See /features/playwright-export.

Is Playwright's Healer the same thing as ZeusQA?

No. Healer repairs a test you already wrote. A ZeusQA run re-derives the steps each time; the Playwright test it exports is a snapshot of one run, which you maintain like any other test.
