About Mixcore

Mixcore is an open-source web CMS built on ASP.NET Core that can be used headless or decoupled. It is meant for teams building multi-purpose web apps, mobile apps and application services who want customizable APIs on a .NET back end. The README describes a back-office portal built on Bootstrap 5, with new portals in Angular and Svelte planned, and the project's topics also mention e-commerce and backend-as-a-service use.

Listed features include support for MySQL, SQL Server, PostgreSQL and SQLite, member roles and permissions, data encryption, multilingual content, media management, SEO features without extra plugins, a Google Analytics dashboard, an in-browser code editor based on Visual Studio Code, a dynamic modular architecture with attribute sets, API-first extensibility and one-step export for backups. The architecture uses ASP.NET Core, SignalR and front-end options such as Angular, React, Vue and Svelte.

The master branch carries the 1.0 long-term-support line, while development continues on a 2.0 alpha branch. Mixcore is licensed under MIT and runs on any platform that supports .NET, so you host it yourself.
