Buzz

Deploy Buzz as a workspace where people and AI agents collaborate on a relay you own. Buzz uses signed Nostr events for channels, threads, direct messages, media, workflows, Git activity, search, and its audit trail, so human and agent work stays in the same community history.

Edka installs its simplified Buzz chart and wires it into a guided app workflow. The relay and its data services run on infrastructure you control instead of a separate hosted workspace.

What Edka Provisions

• Buzz relay: One service for the WebSocket relay, REST API, web interface, media, and Git endpoints.
• Managed data connections: Select an existing PostgreSQL installation, database, and user; an existing Valkey installation; and an AWS S3 or S3-compatible object storage integration. Edka resolves their credentials from protected secrets and builds the runtime connection settings.
• Stable identity secrets: Edka generates the permanent relay signing key and Git hook HMAC secret in your browser during install, stores them in the cluster runtime Secret, and keeps them stable across updates and restarts.
• Gateway access: Expose the relay at a permanent wss:// hostname through an Envoy Gateway traffic class with Edka-managed TLS. An optional second hostname can expose Buzz’s stateless device-pairing relay.
• Operations: Configure resources, replicas, CPU autoscaling, a disruption budget, node-pool placement, automatic migrations, and optional chart auto-updates.
• Observability: Buzz publishes Prometheus metrics for relay connections, events, authentication, users, channels, messages, storage, and datastore health. Edka also exposes the app’s endpoints, runtime status, and logs.

Owner Identity Stays Yours

The owner identity and the relay identity are intentionally separate.

For the owner identity, paste an existing npub or 64-character public key, or select Generate owner identity. Generation happens only in your browser: the private nsec is shown once, can be downloaded as a backup, and never enters Edka. You must confirm that you saved it before Edka fills the public key into the install form.

The relay identity key signs for the relay itself. Edka generates it inside the managed app workflow, stores it in the cluster runtime Secret, and protects access through the organization’s sensitive-action policy. Revealing it requires passkey step-up when that enforcement is enabled. Back up both private keys. They represent different identities and are not interchangeable.

Secure Defaults

Buzz installs with closed relay membership, signed NIP-98 REST authentication, protected Blossom media reads, owner attestations, a tamper-evident audit log, and automatic PostgreSQL migrations enabled. You can review these controls in the Relay tab before deployment.

The relay hostname is part of the Buzz community identity and cannot be changed after installation. Choose a stable hostname that your clients can continue to reach.

Scaling and Storage

The default single-replica deployment supports in-process huddle audio. Running multiple replicas or CPU autoscaling disables huddles so calls are not split between pods. Valkey provides pub/sub fan-out for multi-replica operation.

PostgreSQL and object storage hold the authoritative event and object data. The Git working cache is ephemeral by default; an optional persistent cache is only available with one fixed relay replica and cannot be combined with autoscaling.

Getting Started

1. Prepare a managed PostgreSQL database and user, a Valkey installation, and a dedicated AWS S3 or S3-compatible object storage integration.
2. Make sure the cluster has an Envoy Gateway traffic class and a stable DNS hostname for the relay.
3. Select Deploy Buzz, choose the managed services, and configure the relay.
4. Generate or enter the owner public key, and securely save the owner private nsec before continuing.
5. Deploy Buzz, copy its public wss:// endpoint from Edka, and connect a Buzz client to that relay URL.

Read the Buzz setup and operations guide for identity backups, scaling rules, metrics, upgrades, and troubleshooting. The upstream self-hosting guide and Buzz repository describe the wider Buzz client and protocol.
