What the Service Runs On
Tupshar is a Rust service running on Kubernetes, backed by SurrealDB for document storage. During the research preview it runs as a single replica with no uptime guarantee and no SLA. We may take it down for maintenance without notice.
Self-Hosting
Self-hosting is not available today. It may be offered in a future release once the service design has stabilised. If self-hosting matters to you, let us know — feedback shapes the roadmap.
