All three testing libraries are free and open source. The cost question is entirely about Cypress Cloud — the paid SaaS that Cypress needs for parallel test runs, recordings and analytics.
| Library cost | Parallelization | Dashboard/analytics | |
|---|---|---|---|
| Playwright | free | built in, free | none official (use your CI) |
| Cypress | free | in Cypress Cloud (paid) | Cypress Cloud (paid) |
| Puppeteer | free | roll your own | none |
Playwright (Microsoft) has become the default for new projects, and pricing is a big reason: parallel execution is built into the free framework, so you don't pay a SaaS to run your tests concurrently. It's cross-browser (Chromium, Firefox, WebKit), the API is clean, and it minimizes CI-minute consumption, which keeps your infrastructure bill lower than Cypress's historically single-threaded runs.
Cypress has the friendlier developer experience — the interactive test runner, time-travel debugging, the way it feels to write tests — but its parallel orchestration, video recordings and flake analytics live in Cypress Cloud. After Cypress.io was acquired in 2025, the free Cloud tier tightened (3 users, 30-day retention, an annual results cap). The Starter plan is $75/month; Team is $250+/month; for a mid-size engineering org, Cypress Cloud realistically runs $15,000–40,000/year.
Puppeteer (Google) is lower-level — Chrome/Chromium automation, no test-runner opinions. Reach for it for scraping, PDF generation, screenshots and automation scripts rather than a full E2E test suite.
New E2E suite where CI cost matters: Playwright — the free parallelization alone justifies it. Already invested in Cypress and its DX, with budget for Cloud: Cypress is fine. Automation and scraping rather than testing: Puppeteer.
