I can check if the page is running angular or angular.js by checking window.ng and window.angullar.
Is there any such way to check if the page is using vue from the console, without using vue-devtools
Caution! This will work only if the site you're checking has Vue as global.
Open Console of your Browser and Write Vue, and after that you will see output like this. Remember that in Vue, v is in upper case

Vue as a globalVue is exposed as a global ... it don't look like that at all - but then, I don't put developer version of Vue in productionThere are a couple of ways that you can try to check if the website uses Vue.js without vue-devtools
Check the page's source code
vue keyword.Inspect the DOM
v-, data-v-.Check the browser console
