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.
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.
| ZeusQA | Playwright | |
|---|---|---|
| What it is | Hosted 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 owner | Proprietary SaaS | Apache-2.0, maintained by Microsoft |
| How a test is written | A paragraph of English | Code — TypeScript/JavaScript, Python, .NET or Java. codegen records your actions and writes it for you. |
| Setup | None. Sign up, paste a URL. | npm init playwright@latest, browsers download, and you own a suite from then on. |
| Price | Free for 5 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. |
| Browsers | Chromium only | Chromium, Firefox and WebKit, headless or headed, on Linux, macOS and Windows |
| Deterministic reruns | No — the model re-plans each run, so the same prompt can take different paths | Yes. The same script runs the same way. |
| Speed | About a minute for a typical flow | Milliseconds to seconds per test, once it is written |
| Maintenance | No stored selectors. The prompt is the artefact. | Selector and script maintenance is the main long-run cost. The Healer agent repairs failing tests automatically. |
| Assertions | Named 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 for | Console errors, uncaught page errors and failed or 4xx/5xx requests on every run, each with a severity | Exactly the assertions you wrote. Traces, video and screenshots are configurable. |
| Debugging artefact | Per-step screenshots, a session video and a live browser view | The trace viewer, which is the best debugging artefact in the category |
| CI | First-class. Running in CI is the normal way to use it. | |
| Scheduling and alerting | Not built in either — you use your CI scheduler, or a monitoring tool | |
| Works against localhost | Yes, anywhere your machine or runner can reach | |
| AI features | The product is the model | 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 the test to gate a pull request. Playwright is built for CI; ZeusQA has no CI story today.
- 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.
- Your app runs on localhost or behind a VPN.
- 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 find out what is worth scripting — the same job Playwright's Planner agent does 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?
- Not today. The step scripts are visible in the report, but there is no export.
- Is Playwright's Healer the same thing as ZeusQA?
- No. Healer repairs a test you already wrote. ZeusQA has no stored test to repair — it re-derives the steps each run.
