Hello, i would like to know if it is possible to use the selfhosted react App from the Github in combination with another frontend app with a different framework? I'm currently using VueJS for Frontend and have not worked with react before. Could I host the Loginpage as an react app seperately and direct to it from my vueJs frontend? If yes, what do I have to return to my frontend after the authentication? Is the session stored in cookies or something like that?

This is possible. Your webserver would serve the react app for the /auth/* route, and for other routes, it would server the vue app. The react app would use supertokens-auth-react SDK. The Vue app would use supertokens-website SDK (which is also used inside supertokens-auth-react). Upon login, the session tokens will be stored in the cookies and attached to the API domain + the website domain. So you don't need to do anything special to communicate between the react and vue app.

Oh that's great! Thank you for your quick response 😃
