fedify

Fedify is an open-source TypeScript framework for building ActivityPub-compliant servers, enabling developers to create federated social applications that interoperate with platforms like Mastodon. It is designed for TypeScript developers who want to leverage modern web standards and type safety to implement decentralized, server-side ActivityPub logic without reinventing protocol handling. Its interesting because it simplifies the complex ActivityPub specification into a developer-friendly API, making federated server development more accessible and efficient.
