Hive — Multi-Agent Infrastructure
Self-hosted multi-agent infrastructure with 6-layer security, Docker sandboxing, and $10-29/month operating cost.

System Architecture
The Problem
Cloud AI agent services are expensive, opaque, and vendor-locked. Building multi-agent infrastructure on commodity hardware requires solving security, cost governance, and reliability challenges from scratch.
Approach
OpenClaw-native architecture on a Beelink SER5 mini PC with 6-layer defense-in-depth security, modular domain teams with depth-2 agent nesting, and Docker sandboxing with dropped capabilities.
Architecture
OpenClaw Gateway manages agent lifecycle with depth-2 nesting (orchestrator → team leads → workers). LiteLLM proxy provides multi-provider routing with hard budget caps. QMD hybrid search (BM25 + vector + MMR) provides local semantic memory. Tailscale mesh provides zero-public-port network security. 1Password CLI injects secrets at runtime via tmpfs.
Results
- 22 Architecture Decision Records
- 130+ tasks across 8 completed phases
- 6-layer security model from network to supply chain
- 5+ agents running with zero public ports
- $10–29/month operating cost on commodity hardware
Lessons Learned
Defense-in-depth security on commodity hardware can match cloud-hosted alternatives when each layer (network, secrets, access control, sandboxing, encryption, supply chain) is implemented independently.
