The web has evolved.
Finally, testing has too.
Finally, testing has too.
Fast, easy and reliable testing for anything that runs in a browser.
Install Cypress for Mac, Linux, or Windows, then get started.
A complete end-to-end testing experience.
Install the Cypress Test Runner and write tests locally.
Set up tests
Installing Cypress is simple. No dependencies, extra downloads, or changes to your code required.
Write tests
Write tests easily and quickly, and watch them execute in real time as you build your web application.
Build up a suite of CI tests, record them and gain powerful insights
Run tests
Debugging your tests in CI is as easy as running tests locally. With built in parallelization and load balancing.
Record tests
Record CI test data, screenshots and video - and view aggregated, next-level insights in your Dashboard.
Test your code, not your patience.
Cypress is the new standard in front-end testing that every developer and QA engineer needs.
Developer-friendly
Cypress has been made specifically for developers and QA engineers, to help them get more done.
Open source
Cypress benefits from our amazing open source community - and our tools are evolving better and faster than if we worked on them alone.
Built from the ground up
Cypress is based on a completely new architecture. No more Selenium. Lots more power.
What sets Cypress apart?
Time travel
Cypress takes snapshots as your tests run. Simply hover over commands in the Command Log to see exactly what happened at each step.
Debuggability
Stop guessing why your tests are failing. Debug directly from familiar tools like Chrome DevTools. Our readable errors and stack traces make debugging lightning fast.
Real time reloads
Cypress automatically reloads whenever you make changes to your tests. See commands execute in real time in your app.
Automatic waiting
Never add waits or sleeps to your tests. Cypress automatically waits for commands and assertions before moving on. No more async hell.
Do you Cypress? Say it!

really impressed with @Cypress_io. it's a great tool in itself, but the documentation is ✨stellar✨i'm sold.

Thanks to @Cypress_io, I no longer hate development testing!

Don't think I've experienced joy using a testing framework until I came across @Cypress_io so easy, simple, intuitive and troubleshooting is a breeze. I've tried selenium and puppeteer but this is hands down what devs need especially when working alone, every min saved is gold!

I spent today experimenting with @Cypress_io and navigating the docs and was thoroughly impressed with the tool! I’m a fan in just a few hours.

What's NOT to love about @Cypress_io? 🤷♂️
— DevCast (@devcastcode) October 24, 2019
Excellent documentation and tutorials that make you productive in under 30 minutes. A better way to integrate #dev and QA teams. Time travel with snapshots.
🔥 #Testing is now something to look forward to (seriously)! 🔥

Replaced Protractor, Karma and Jasmine in Angular all for @Cypress_io. Been loving the testing experience and am not planning on looking back. Thanks for making testing great again! ™️

— Manish (@thatonedroid) May 30, 2019
But it sure saves your ass after a major refactor. Having the confidence everything works as before is 🔥.

I just tried out @Cypress_io for the first time and found myself productve within about 10mins. My pseudocode suggestions for how it would work were also exactly how it worked! eg. cy.get('button').contains('complete').click();

Been looking for a testing solution for our QA process and found @Cypress_io. This thing is brilliant🤯

I just felt in love with @Cypress_io The first time I test a real application and in just a few minutes I could test an entire functionality 🥰 I also love how easy is to read the code. Cmon, to be honest, even a non-programmer could read it!
— Karen Cubero 🤘🏻 (@kcubero27) September 20, 2019

@Cypress_io is the first end-to-end test tool that didn't test my patience. Time from install to first "real" test running was three hours (including a coffee break).
