Why do you support only a limited no of testing tools?

StoreHippo supports a limited number of testing tools because we can only support the tools which send request from user agent side and not otherwise.

StoreHippo is a java script platform. So if the testing tool sends the request with the user agent, only in that case JavaScript will be resolved by Prerender server. Otherwise, the java script is not resolvable and that tool will not be able to perceive our SEO (like meta tags, OG tags etc).      

Some of the testing tools supported by StoreHippo are Dareboost, Woorank, etc.
