As an "information connector" in the Web3 space, RSS3's compatibility covers multiple scenarios in Web2, Web3, and even AI fields, which is one of its core advantages over traditional RSS and single-platform tools. In the Web3 domain, it connects mainstream social protocols like Lens, Farcaster, and Nostr, building bridges between different applications and users; in the Web2 domain, it achieves content interoperability with platforms like Douyin and Weibo through technical adaptation, allowing users to synchronize content to the open network without giving up their existing usage habits; at the same time, it is also compatible with multimedia content like Spotify audio and podcasts, meeting the needs for diverse information aggregation. This cross-platform capability not only allows users to access all the content they care about from one entry point but also enables creators' content to break through platform throttling and bans, truly realizing the free flow of content.
