SHM
SHM (Self-Hosted Metrics) is privacy-first, agnostic telemetry for self-hosted software—collect usage stats, verify active instances, and understand adoption without spying on users. Instances sign payloads with Ed25519; PostgreSQL stores JSON metrics behind a single Go binary with an embedded dashboard (port 8080). AGPL-3.0; upstream lives under the kOlapsis GitHub organization.
