5.7Swarm vs Orchestrator Comparison
| Dimension | Orchestrator | Swarm |
|---|---|---|
| Coordination | Centralized (one coordinator) | Decentralized (reconciler at the end) |
| Speed | Sequential delegation | Fully parallel |
| Coverage breadth | Directed (orchestrator plans) | Exploratory (each agent explores) |
| Duplication risk | Low (orchestrator prevents overlap) | High (agents are independent) |
| Single point of failure | Orchestrator | Reconciler |
| Best for | Structured testing | Exploratory coverage |
| Complexity | Medium | High (reconciliation is hard) |
