Covers downloading the Buzz desktop app, generating a public/private key identity, converting the public key to hex format for the relay owner configuration, deploying the Buzz template on a KVM 2 VPS plan, and connecting the desktop client to the self-hosted relay. Also discusses the relay's component services (MinIO for file storage, PostgreSQL for chat history), agent security settings (controlling who can invoke agents), and current limitations around private community enforcement via environment variables. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What services does the Buzz relay consist of when self-hosted? The Buzz relay runs as multiple Docker containers including a MinIO service for storing uploaded images and files, a PostgreSQL database for storing and searching chat conversations, and the relay service itself. These components must all be running for the relay to function properly, and Hostinger's VPS template provisions all of them automatically. _Developers running their own Buzz relay can track infrastructure updates and community tips on daily.dev._ ### How do I get the hex public key needed for the Buzz relay owner pubkey field during VPS setup? Copy your public ID (npub format) from the Buzz desktop app by clicking 'join a community' — it appears at the bottom of that screen. Then open the Nostr key conversion tool, select 'load a pubkey from npub hex', paste your public key, click load, and copy the hex value (the bottom result). That hex string is what goes into the relay owner pubkey field during VPS provisioning. _Developers setting up Nostr-based tools find protocol-specific setup details like this faster on daily.dev._ --- Tags: [#ai-agents](https://daily.dev/tags/ai-agents), [#docker](https://daily.dev/tags/docker), [#self-hosting](https://daily.dev/tags/self-hosting) [View this post on daily.dev](https://daily.dev/posts/setup-buzz-on-hostinger-vps-easy-self-hosting--qyugoqwhr) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Setup Buzz on Hostinger VPS (EASY Self-Hosting!)","url":"https://daily.dev/posts/setup-buzz-on-hostinger-vps-easy-self-hosting--qyugoqwhr","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/setup-buzz-on-hostinger-vps-easy-self-hosting--qyugoqwhr"},"datePublished":"2026-08-11T09:23:21.990Z","dateModified":"2026-08-11T09:42:49.832Z","description":"A walkthrough of self-hosting the Buzz relay (an AI agent collaboration platform built on the Nostr protocol) on a Hostinger VPS.
