The short version
- Each has a real cost: Playwright requires programming language knowledge; not suitable for non-technical QA staff; pytest there is no corporate owner or dedicated support organisation, so response time on bugs or security issues depends on volunteer maintainer availability unless a Tidelift subscription is purchased separately.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Playwright
- Requires programming language knowledge; not suitable for non-technical QA staff
- WebKit implementation less mature than Chromium; occasional webkit-specific issues
- Mobile browser testing relies on emulation, not real devices
- No managed cloud infrastructure; users must host CI/CD runners or pay for third-party services
pytest
- There is no corporate owner or dedicated support organisation, so response time on bugs or security issues depends on volunteer maintainer availability unless a Tidelift subscription is purchased separately.
- The plugin ecosystem's quality and maintenance level varies widely between plugins, and a team building a workflow around several plugins takes on the risk of any one of them going unmaintained.
- Its assert-rewriting magic, while convenient, can behave unexpectedly in edge cases involving custom assert helpers, which occasionally confuses developers used to explicit assertion methods.
- Large test suites with many fixtures can develop hard-to-trace fixture dependency chains, since fixtures can depend on other fixtures in ways that are not always obvious from a single test file.
- Being free and volunteer-maintained, roadmap direction is set by contributor consensus rather than a company with commercial incentive to prioritise enterprise-requested features quickly.

Questions people ask
- Is Playwright or pytest better?
- Neither clearly leads. Playwright starts at Free and pytest at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
