Summary
Creator Magic walks through deploying a self-hosted Buzz AI relay on Railway in under five minutes, motivated by Jack Dorsey’s public post about self-hosting Buzz that drew 400,000 views. Buzz, the open-source Apache 2.0 messaging and AI agent platform from Block, separates the desktop client from the relay server — and by default users run on Block-hosted infrastructure. This tutorial shows how to move your relay onto your own server so you control where messages, files, and AI agent outputs are stored.
The process requires pasting a single public key into Railway’s deploy interface — no terminal, no SSH, no Linux. Railway provisions the full stack automatically: the Buzz app itself, a database, Redis, and S3-compatible storage. The video covers pricing honestly: Railway’s hobby plan starts at $5/month with $5 of usage included, and actual costs scale with relay activity. Optional steps include adding a custom domain via Cloudflare DNS records and locking the relay to members-only access via a single Railway environment variable.
The creator explains his own three-relay strategy — a public community relay on Block’s servers, a private business relay for client work, and a members-only relay for his Skool community — as a practical framework for deciding what to self-host versus delegate. The video is especially relevant for teams using Buzz AI agents to route tasks, since self-hosting determines where agent-generated content and conversation transcripts actually live.
