Crabbox.sh introduces Pond, a lightweight grouping system for managing related runtime leases across multiple cloud providers and transport planes.

Pond groups related leases by a reserved pond=<name> provider label, allowing discovery and collective release across providers without requiring a central cluster object; a pond exists as long as at least one active lease carries the label.

Three transport planes enable connectivity: Tailscale provides true peer-to-peer mesh with <slug>.cbx DNS names (Hetzner, Azure, GCP); URL Bridge surfaces provider-native HTTP(S) endpoints (Islo, E2B, Modal, Cloudflare, Tensorlake); SSH-mesh offers operator-side ssh -L tunnels (Hetzner, Azure, GCP, AWS, Proxmox, static ssh, RunPod, exe-dev, Daytona, Sprites, Namespace, Semaphore, local-container, Parallels).

Pond is in preview for v0.x; the reserved pond= label key is intended to stay, but metadata shape and command flags may evolve before v1.0.
