Yes, for IPFS applications in Go, **Kubo** (previously known as go-IPFS) is indeed the best choice. Written in Golang, Kubo is the most widely used IPFS client and serves as the primary reference implementation. It is highly optimized for performance, scalability, and stability, which makes it ideal for larger, production-oriented applications and server-based environments.

Kubo's design benefits from Golang's efficiency in handling concurrency and networking, which is particularly useful for IPFS nodes that need to manage multiple connections and large datasets. This implementation also has the most extensive support for IPFS features, community tools, and network updates, ensuring it is frequently maintained and compatible with the broader IPFS ecosystem.

If your project is heavily backend-focused or requires consistent uptime and reliability, Kubo would be the preferred choice due to these performance and compatibility advantages. For Golang developers, it is a natural fit and continues to be the most robust option within the IPFS client landscape.
