Cypress Cloud charges $75 a month just to run your tests in parallel. AVA does it free. Every test file runs in its own isolated Node.js process with true concurrent execution out of the box. No shared state between tests, no flaky failures. AVA has 20,000 stars on GitHub and 570,000 weekly npm downloads from developers who've trusted it for over a decade. It ships with built-in TypeScript support, snapshot testing, and an API so minimal you learn it in minutes. Star it if this saved you money.
