A bit of history...

The Appeal

• Easy to setup (yarn add cypress --save-dev)
• DOM Time Traveling
• Great documentation
• Tests written in JS
• Executed in the same run loop as the application
• Easy to run tests (headed or headless)
• Easy to debug
• No Selenium/PhantomJS/Casper shenanigans
• Works with SPA written with frontend frameworks (React/Redux)
• Full Dashboard for test results (paid version only)
• Can test APIs as an alternative to postman
• Compatible with CI servers
• Runs on Docker
• Them screenshots and videos 

Caveats

• Not a unit testing tool. E2E only
• Dashboard is paid version only (optional web-based companion to the Test Runner which is free and open source)
• No multi-tab support
