Show HN: Compare Two Samples

Author here: I created a simple tool to compare two samples inside the browser.

The tool was created with Angular 4 and uses Universal. Currently I am thinking about creating a service that allows developers to compare software metrics of different versions of their software to detect performance regressions. But I am not sure yet how to package that as a SaaS service.

I'd be grateful for any feedback about the site (especially about how to make the whole page load faster).
