We've setup a demo app for Inertia.js, called Ping CRM. This application is built using Laravel and Vue.js. You can find the source code on GitHub.
The Ping CRM demo is hosted on Heroku, and the database is reset every hour. Please be respectful when editing data.
In addition to the Vue.js version of Ping CRM, there is now also an officially maintained Svelte version of it, which you can find here.
Beyond our official demo app, Ping CRM has also been translated into numerous different languages and frameworks.
