Spot visual bugs before your users do

Percy helps teams automate visual testing. It captures screenshots, compares them against the baseline, and highlights visual changes. With increased visual coverage, teams can deploy code changes with confidence with every commit.



Percy adds visual testing to your existing workflow by integrating with test automation frameworks or directly with your application.


Percy captures snapshots, makes pixel-by-pixel comparisons against baselines, and detects visual bugs in your UI with every commit.


Percy groups visual changes and ignores noisy elements for faster reviews. Comments and notifications ensure that teams stay updated.

Luis H. Ball Jr. @luishbjr1 @browserstack Local appreciation tweet 🥰 Browser’s refusal to ship meaninful JS feature flags makes it necessary to be able to test on older versions.Local makes that a breeze ⛵.
Fatih Battal @fatihtweeting @browserstack I love you😘 Nothing more. That's it.
Kevin Basset @kvnbsst Big fan of @browserstack for cross-browser testing. If you're building a #PWA, it's an absolute must-have. #nocode #iphone #safari #web #browser
Rajendra Kadam @rajendra_ak Use @browserstack to automate tests on many more devices than those in your farm.
Code With Caen @CodeWithCaen Trying out @browserstack and am completely blown away. Currently playing around with visual testing using Percy. Super excited I got a sponsored #opensource plan too!
