Admingen is a Headless CMS generator. Define entities, fields, relationships and access in one model. The generator produces a backend, API contract, admin and migrations. The generated application runs independently: the generator does not serve its requests.

From model to application

Saving the model changes the manifest. Generate writes project files. Applying migrations separately changes PostgreSQL. A public website is a separate API client.
