Cursion's answer:
Cursion's answer:
Scanerr began like so many other software tools, the founder solving their own problems.
The first iteration of Scanerr was a simple Python script used to ensure the founder's websites didn't break after updates.
Not long after, a few companies reached out and wanted to use the technology for their own processes - and Scanerr was born!
Cursion's answer:
We're fortunate to serve companies of all sizes. From the enterprise to the startup, Scanerr is constantly helping developers and teams uncover bugs, bottlenecks, and breaking changes to their web apps.
Most of our customers are from the web development, hosting, and digital marketing industries.
Cursion's answer:
Scanerr provides a comprehensive assessment of your website by collecting and analyzing the Page Source, Console Errors/Warnings, Screenshots, and over 70 Performance Metrics. Scanerr also uses an Advanced, Proprietary Algorithm for detecting visual changes on a website in real-time.
Cursion's answer:
Unlike its competitors, Scanerr performs Regression Testing by comparing more than just screenshots. By combining our Advanced, Proprietary Visual Regression Algorithm, and over 70 Performance Metrics with Browser data - Scanerr provides a holistic assessment of your site's health and stability.
