Yancy is a simple content management system (CMS) for administering content in a database. Yancy accepts a configuration file that describes the data in the database and builds a website that lists all of the available data and allows a user to edit data, delete data, and add new data.

Yancy uses JSON Schema to define the data in the database. The schema is added to an OpenAPI specification which creates a REST API for your data.

Yancy can be run in a standalone mode (which can be placed behind a proxy), or can be embedded as a plugin into any application that uses the Mojolicious web framework.

Yancy can manage data in multiple databases using different backends (Yancy::Backend modules). Backends exist for Postgres via Mojo::Pg, MySQL via Mojo::mysql, SQLite via Mojo::SQLite, and DBIx::Class, a Perl ORM

Mojolicious Plugin

Yancy is primarily a Mojolicious plugin to ease development and management of Mojolicious applications. Yancy provides:

For information on how to use Yancy as a Mojolicious plugin, see Mojolicious::Plugin::Yancy.

Example Applications

The Yancy Git repository on Github includes some example applications you can use to help build your own websites. View the example application directory.

Yancy Plugins

Yancy comes with plugins to enhance your website.

  • The Auth::Basic plugin provides a simple, password-based authentication system for the Yancy editor and your website.

  • The Form plugin can generate forms for the configured collections, or for individual fields. There are included form generators for Bootstrap 4.

More development will be happening here soon!

Standalone App

Yancy can also be run as a standalone app in the event one wants to develop applications solely using Mojolicious templates. For information on how to run Yancy as a standalone application, see Yancy::Help::Standalone.


This application creates a REST API using the standard OpenAPI API specification. The API spec document is located at /yancy/api.


See Yancy::Help::Config for how to configure Yancy in both plugin and standalone mode.
