A: Hi! We don't have a demo page of this type but it's a good idea, we'll try to create one. About speed and crawlers.. Reboo generates two files, a Css and a JS, that are usually small. The size depends on how many apps you use and on the number of changes. If i.e. you use only the Restyler app the JS file is empty, no javascript is used. So it depends on the usage. The generated files are saved on a CDN. You can test performances of a file example: https://cdn.reboo.io/embed/dc03f44467f8438b6/reboo.min.css
