Testing Library vs Cypress

Free and open source

From $75 per month (Cloud, entry team plan)

Free and open source. You pay in engineering time and CI minutes.

You only pay for Cypress Cloud. Costs scale with recorded test results, so a large suite on every PR is the expensive shape.

Everything, self-hosted

The test runner is free forever. Cypress Cloud free tier covers a limited number of recorded test results per month.

• Tests survive refactors because they assert on user-visible output, not internals.
• Accessible-role queries push teams towards accessible markup as a side effect.
• One idiom across every major front-end framework.

• The interactive runner is the best onboarding experience in E2E testing; a new developer writes a passing test in minutes.
• Excellent documentation and one of the largest plugin ecosystems.
• Component testing and E2E in one tool with one config.

• Deliberately makes implementation-detail testing hard, which frustrates teams used to shallow rendering.
• Async utilities and act() warnings are a common source of confusion.
• Needs a runner and a DOM environment alongside it.

• Runs in the same event loop as your app, which historically meant no multi-tab, multi-origin or iframe-heavy testing without workarounds. Support has improved but the model still constrains you.
• JavaScript and TypeScript only.
• Meaningful parallelisation effectively requires paying for Cypress Cloud.

Any front-end team writing component tests, regardless of framework.

Front-end teams who value developer experience and live in a single-origin JavaScript app.
