About Castopod

Castopod is a free and open-source podcast hosting solution for podcasters who want to engage and interact with their audience. It lets you publish and manage a podcast on your own server instead of a third-party hosting service. The project's topics point to analytics, self-hosting and the Podcasting 2.0 initiative, and it is built on the CodeIgniter 4 PHP framework.

Castopod comes pre-packaged with all the static assets and dependencies it needs, so you download it and follow the getting-started page to install it. Translations are managed through Crowdin, and the repository has contribution guidelines. The GitHub repository is a synchronized read-only mirror, and the maintainers state that contributions made on any repository other than the original at code.castopod.org will not be accepted.

Security issues should be reported by email to the address in the README. The software is licensed under AGPL-3.0, which applies if you run a modified version as a public service.
