If you are looking for options to test your web app hosted on your own machine (e.g., laptop) remotely with someone, I recommend using a service called ngrok. https://ngrok.com/ It has many usages, but in the context of testing an app hosted on your own machine, the most important part is giving you a public URL that will redirect all the requests to your local webserver (e.g., Apache, Nginx, or whatever server you are running). You can give this URL to a testing participant without the need to host the app on a remote server. For instance, if you are testing your app using a sever on your machine, typically you can access your app in a URL like: http://localhost:3000/?study=11 Using ngrok, you will have a dynamically generated URL like the following: https://3ebe3c019867.ngrok.io/ The service will redirect requests to https://3ebe3c019867.ngrok.io to http://localhost:3000 You can then share the following link with your testing participant for the participant to use your app. https://
