LeadCMS
Open source headless CMS and CRM written in .NET, for publishing website content and tracking customer journeys.
LeadCMS is an open source headless CMS and CRM written in .NET. It stores its data in PostgreSQL, exposes a RESTful API with OpenAPI documentation, and includes an admin UI. Functions can be added through a plugin system with an IPlugin interface.
The installation guide starts the core and its PostgreSQL database with Docker Compose from the leadcms.deploy repository, and the ops guide describes that compose file as a sample for evaluation or a starting point for a production setup.
Worth knowing
