Open-source Spreaker alternatives

microfeed is a lightweight content management system that runs on Cloudflare, aimed at technical individuals who want their own CMS without operating servers. You can publish audio, video, photos, documents, blog posts and external links to a feed that is available as a web page, RSS and JSON, so it also works as a podcast host.

Content can be managed in the built-in admin dashboard or by an AI agent through the official @microfeed/cli, which is why it describes itself as an agentic CMS. It is built on Cloudflare services including Workers, D1, R2, Queues and Zero Trust, according to the repository topics, and also functions as a headless CMS with an API. The code is TypeScript.

microfeed is licensed under AGPL-3.0 and deployed to your own Cloudflare account, so there is no separate vendor-hosted version. It suits creators, podcasters and developers who want a serverless, low-maintenance place to publish content.

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.
