Which one should you pick?
Pick Cypress if…
You want the most polished developer experience: an in-browser test runner, time-travel debugging, automatic retries and first-class component testing, and your targets are Chrome, Edge and Firefox.
Pick Playwright if…
You need WebKit (Safari engine) coverage, more than one language (TypeScript, Python, Java, C#), multi-tab or multi-origin flows, or free built-in parallel execution without a paid dashboard.
You have an existing Cypress suite you like and want Playwright for new cross-browser or multi-tab scenarios. TestingBot runs both on the same grid, in parallel, in one dashboard.
What are Cypress and Playwright?
Two modern JavaScript testing frameworks with different architectures. The same goal: drive a browser to automate end-to-end testing.
Cypress
Released 2017 · Cypress.io · MIT
Cypress is a JavaScript end-to-end testing framework that runs your tests inside the browser, in the same run loop as your application. That architecture gives it direct DOM access, automatic retries and time-travel snapshots out of the box.
Cypress is known for its developer experience: a built-in test runner, real-time reloads, a visual debugger and strong component testing. The in-browser model also limits it to JavaScript and TypeScript, a fixed set of Chromium-based browsers plus Firefox, and single-tab flows.
- JavaScript and TypeScript only
- Auto-retries, time-travel debugging, component testing
- Chrome, Edge, Firefox, Electron · no WebKit/Safari
Playwright
Released 2020 · Microsoft · Apache 2.0
Playwright is an end-to-end testing framework built by Microsoft that controls Chromium, Firefox and WebKit through a single API. It drives the browser out-of-process over the DevTools protocol (and its own bridges for Firefox and WebKit).
Playwright was designed for scale: bindings in five languages, native multi-tab and multi-origin support through browser contexts, built-in parallel workers, network interception and a rich Trace Viewer, all included.
- TypeScript, JavaScript, Python, Java, C#
- Auto-wait, browser contexts, Trace Viewer, free parallel
- Chromium, Firefox, WebKit · no IE / legacy Safari

Feature notes reflect Cypress 13.x and Playwright 1.x as of 2026. Both frameworks run on TestingBot's cloud, Cypress through the testingbot-cypress-cli and Playwright through the wsEndpoint connection.
Logging in, asserting the result
A login flow with built-in retries (Cypress) and auto-wait (Playwright). Both run on the same TestingBot grid.
Cypress + TypeScript
login.cy.ts
// run via: testingbot-cypress run describe('login', () => { it('redirects to the dashboard', () => { cy.visit('https://app.example.com/login'); // auto-retries until actionable cy.get('#username').type('jane@example.com'); cy.get('#password').type('••••••••'); cy.contains('button', 'Sign in').click(); cy.url().should('include', '/dashboard'); cy.contains('h1', /welcome, jane/i).should('be.visible'); }); });
Playwright + TypeScript
login.spec.ts
// playwright.config.ts → set TestingBot wsEndpoint import { test, expect } from '@playwright/test'; test('login redirects to dashboard', async ({ page }) => { await page.goto('https://app.example.com/login'); // auto-wait, no explicit wait needed await page.getByLabel('Username').fill('jane@example.com'); await page.getByLabel('Password').fill('••••••••'); await page.getByRole('button', { name: 'Sign in' }).click(); await expect(page).toHaveURL(/\/dashboard/); });
The Cypress spec runs through the testingbot-cypress-cli; the Playwright test connects to the wsEndpoint. Both appear in the same TestingBot dashboard.
When to choose which
Choose Cypress when
- You want the best in-class developer experience: in-browser runner, time-travel snapshots and readable failures.
- You do component testing alongside end-to-end tests and want one tool for both.
- Your targets are Chrome, Edge and Firefox, with no WebKit or Safari-engine requirement.
- Your team is fully JavaScript or TypeScript and values a gentle learning curve.
- Your flows stay within a single tab and mostly a single origin (cy.origin helps, within limits).
Choose Playwright when
- You need WebKit coverage to approximate Safari, which Cypress cannot drive.
- Your team writes Python, Java or C# as well as JavaScript and wants one framework across all of them.
- Your tests open multiple tabs, windows or origins, which Playwright handles natively through browser contexts.
- You want free, built-in parallel execution without a paid dashboard subscription.
- You want the fastest CI runs and trace-based debugging with the Playwright Trace Viewer.
Stop choosing, run both on the same grid
Run Cypress through the testingbot-cypress-cli and connect Playwright through its wsEndpoint. Your tests share the same 6100+ browsers and devices, the same dashboard, the same parallel slots and the same EU data residency, with no Cypress Cloud subscription required.
- Cypress parallelisation without a Cypress Cloud plan
- Side-by-side test history for both frameworks
- Free for open source, both frameworks
Frequently Asked Questions
The questions teams ask before picking, or migrating between, these frameworks.
Is Playwright better than Cypress?
Neither is universally better; they fit different teams. Playwright is more flexible: it drives Chromium, Firefox and WebKit, supports five languages, handles multiple tabs and origins natively, and parallelises for free. Cypress is loved for its developer experience: an in-browser runner, time-travel debugging and first-class component testing. Pick Playwright for breadth and scale; pick Cypress for ergonomics within its constraints.
Should I migrate from Cypress to Playwright?
Only if you are hitting Cypress's limits. If you need WebKit (Safari) coverage, more than one language, multi-tab or multi-origin flows, or free parallel execution, Playwright removes those constraints. If your Cypress suite is stable, JavaScript-only and within a single tab, the migration is rarely worth the effort. Many teams keep their Cypress suite and add Playwright for new cross-browser work.
Does Cypress or Playwright support more browsers?
Playwright supports more rendering engines. It drives Chromium (Chrome, Edge), Firefox and WebKit, which approximates Safari. Cypress runs on Chromium-based browsers (Chrome, Edge, Electron) and Firefox, with experimental WebKit support. Neither drives the real Safari binary or Internet Explorer; for those you need Selenium. TestingBot runs both frameworks across its browser grid.
Which is faster, Cypress or Playwright?
Playwright is usually faster for full suites, mainly because it parallelises across workers for free out of the box and drives the browser out-of-process. Cypress runs each spec in a single browser instance and needs Cypress Cloud or a cloud grid to parallelise. On a single spec the difference is small; across a large suite, parallelisation is the deciding factor. Running either on TestingBot's grid parallelises across browsers regardless.
Can Cypress or Playwright test mobile apps?
Neither tests native mobile apps. Both offer mobile viewport emulation in Chromium, but cannot drive native iOS or Android apps. For real mobile testing you need Appium, XCUITest, Espresso or Maestro. TestingBot runs all of these on real iOS and Android devices.
Do I need Cypress Cloud, or can I parallelise for free?
Playwright parallelises for free with its built-in worker pool. Cypress's own parallelisation and recording run through Cypress Cloud, a paid subscription. TestingBot is an alternative for Cypress: the testingbot-cypress-cli runs your specs in parallel across Chrome, Edge and Firefox on the cloud grid, with live logs and video, and no Cypress Cloud plan. You set the parallel count in testingbot.json.
Can I run Cypress and Playwright on TestingBot?
Yes, both run on the same TestingBot cloud. Cypress runs through the testingbot-cypress-cli npm package, configured with a testingbot.json file and started with testingbot-cypress run. Playwright connects via its wsEndpoint to wss://cloud.testingbot.com/playwright. Tests from both show up in the same dashboard, share parallel slots, and benefit from the same EU data residency, video recording and CI/CD integrations. Both are free for open source projects.
