Kubo is the pioneering implementation of the Interplanetary File System (IPFS), a key Web3 protocol, coded in Go. As the most prevalent IPFS implementation, Kubo facilitates content-addressing and interoperability with HTTP, leveraging IPLD data models and libp2p networking. Kubo supports operations as an IPFS node within both LAN and WAN environments, features HTTP Gateway for content retrieval, and offers an HTTP RPC API for daemon control. Its comprehensive CLI and WebUI simplify node management, while content blocking features aid public node operators. Kubo’s modular architecture and extensive features make it indispensable for developers and operators engaged in decentralized web endeavors.
