What is sunshine?

Sunshine, written as San Shuai in Chinese, describes itself as an open source, decentralized lifestyle community aimed at young men. The README explains that the project started after a Chinese term the community uses for itself was blocked on major social platforms, and the creators decided that rather than depend on a platform that can silence a word at will, they would build their own space where no single company controls what can be said. The repository is currently just a starting point rather than working software. It lays out the project's core principles: the code will be fully open on GitHub under the MIT License so anyone can view, modify, or use it commercially, the platform is meant to be decentralized so content belongs to creators rather than any one company, and it aims to support a federated setup where separate people can each run their own connected instance with no central authority able to silence anyone. The planned technical direction includes a Flutter app so the same code covers both iOS and Android, the ActivityPub protocol used by federated platforms like Mastodon, a self hostable lightweight backend that can be deployed with Docker, and distributed storage such as IPFS so content cannot easily be deleted. The README closes by inviting developers in any language, designers, and anyone interested to get involved through GitHub, and frames the project as wanting mutual respect between different online communities rather than conflict with any particular platform.
