Offline capability

Yes, absolutely. SurveyJS is designed to work fully offline and can run entirely on the user's device without a backend. In offline mode, survey responses are stored locally in the browser (using localStorage). When internet access is restored, the saved data is synced back to your server.

To enable offline support in your application, you'll need to:

• Detect when the user is offline.

• Save survey results locally while there's no connection.

• Listen for reconnect events and sync the stored data once the connection returns.

This makes SurveyJS a reliable choice for applications used in areas with patchy or no internet access. Please refer to this dedicated article on surveyJS offline capabilities to learn more.
