To help evaluate a continuous integration server like Bitrise, demo apps are ready-to-build mobile apps that can be used to explore the product's features and get started with setup, integration, and configuration. Demo apps are already integrated into the platform and don't require connecting a GitHub or GitLab account. Users can create a free Bitrise account and run a demo app by selecting the project type, which currently has four options: iOS, Android, Flutter, and React Native. Once the build has started, users can view the build log, download it, and view the YAML file. The demo apps are not connected to repositories and certain features are unavailable, but users can check their credit usage on the account overview page. Users can delete the demo app from their account by clicking the "Delete app" button on the App settings page.
