Summary
Keith AI demonstrates moving a Buzz team workspace off Block’s hosted infrastructure and onto a fully self-hosted relay, integrated with local AI models via LM Studio for a setup that operates entirely without an internet connection. Buzz is an open-source communication platform built on the Nostr protocol, which grants users cryptographic identity ownership through public/private key pairs — meaning account identity and message data are not tied to any company’s servers and survive even if the platform shuts down.
The video covers three relay deployment paths in practical detail: a home server running on a Blink Home Box mini PC, a VPS option with a 10% discount code, and a one-click Railway deployment that provisions Buzz alongside Redis, Postgres, and an object storage bucket automatically. Keith walks through connecting a custom domain via Namecheap DNS records, configuring Mesh LLM for shared compute across a Buzz community, and integrating LM Studio models including Hermes and OpenCloNa. A live demonstration proves offline capability by disabling Wi-Fi entirely while the Buzz AI agent continues responding — validating the fully air-gapped architecture.
The tutorial is particularly relevant for teams experiencing reliability issues with Block’s shared relay during peak usage, or for organizations where data custody requirements make third-party hosting non-viable. The 34-minute runtime covers six discrete topics systematically, from Nostr identity concepts through relay hosting options to local model execution.
